2016 has been a busy year for the Society but it is with sadness that we say goodbye to a valued member, Ray Seacombe, whose obituary is below.
We wish you all the very best for 2017 and will catch up with you again in the New Year.
Welcome to the November 2016 issue of Broadband Journal!
Our friend and colleague, Ray Seacombe, sadly passed away on 19 October 2016 at the age of 82.
Ray had a long and successful career in the cable television industry. After leaving South East Essex Technical College, Ray worked in the surface coating industry before spending three years in the RAF as an air radar fitter. Ray became involved in cable when he joined Teleng Ltd in 1958 as a planning engineer and where he eventually rose to chief systems engineer. In 1968, he joined Rediffusion Engineering as a liaison engineer and then British Relay (subsequently Visionhire) in 1974, rising to become chief engineer. Ray spent some time with BT in the Broadband Services Division before joining City Centre Cable and CUC Cablevision in the early 1990s.
Ray first joined the SCTE in 1961 and was elected onto
the SCTE Executive Committee in 1966, remaining on the Committee until 1995. This represented some 30
years of valuable service to the Society, including two terms as President in 1971 and 1987.
For most of his time with the SCTE, Ray served on the international standards committees and chaired the British Standards Committee for Cable Networks. Ray also regularly lectured and wrote excellent technical articles for the SCTE during his time on the Committee and also designed the original SCTE ‘bowtie’ logo.
In 2004, Ray was awarded the SCTE Tom Hall Award for his outstanding
contribution to the cable industry. In all, Ray made a considerable contribution to the
Society and his legacy is the continuing high standards which he helped the Society to achieve.

Book now for SCTE Benelux Gala Dinner
Don’t miss this year’s sumptuous Benelux Gala Dinner on
2 February 2017 at Montfoort Castle (Kasteel Montfoort) in the
Netherlands. The black tie dinner will be preceded by a drinks
reception, followed by a four-course banquet.
Montfoort (or Montfurt) Castle is in the Dutch city of Utrecht.
It was built in 1163 by Bishop Godfrey to protect the diocese
from attack. The name comes from 'Mont Fortis’ or "strong
mountain”. The castle was destroyed in 1672 during an invasion
of French troops under the leadership of Louis XIV – however,
the old gatehouse and an octagonal tower remain standing.
The Montfurt family was the principal owner of the castle after
the bishop up until 1648, when it sold the building to the city
authorities. Since the beginning of the 19th century, the castle
has been a hostel, then a school for girls and, since 1989, a
restaurant that also hosts corporate meetings.

The Path to Digitisation By Rahul Nehra, Honorary National Secretary, SCTE India
SCTE India sums up digital and cable developments in India over 2016.
As the year ends, the digital
world of India has unfolded at a
pace which has surprised many.
2016 is set to be remembered
as a year when the world of
multimedia, multiscreen and
quadruple play embraced users
from the cities to the villages.
This shift has a few key contributors such as Reliance Jio;
APSFL; Amazon; Zee; Hotstar; Airtel; Google; Facebook;
Vodafone; MIB and MOC.
Launches and mergersLet's start with the biggest and boldest shift, the Reliance Jio
wake up! This big announcement is bound to have ramifications
for the entire telecoms sector - Reliance Jio has kicked off a
digital revolution. Chairman, Mukesh Ambani, commercially
launched the group's telecoms venture, Jio, on 1 September
2016 offering voice free of charge for life, even while roaming,
besides offering data at around a fifth of industry rates. As per
the company's welcome offer, the data will be free of charge for
all subscribers until the end of this year.
Hailing mobile internet as the future, Ambani said there are no
doubts that it is a life-changing, world-changing technology
for this century. He also added that technology is a huge
opportunity and those who took risks would reap rewards. So,
"Jio is not really a telecom company. It is a tech company," he
told The Times of India.
Confident of a bright future, Ambani said that Jio would
enable India to be among the top 10 countries in broadband
and internet access within the next few years and is aiming to
acquire 100 million customers in the shortest possible time.
Meanwhile, a merger changed the global numbers' game in the
DTH world with the merger of Dish TV and Videocon D2H as
a single DTH company. Ending months of speculation, India's
largest Direct-To-Home (DTH) player Dish TV and NASDAQ-
listed Videocon d2h (Vd2h) decided to merge operations to form

one of the largest Pay TV operators in the world with 27.6 million
net subscribers. The Board of Directors of the two companies
approved a scheme for amalgamation. Dish TV shareholders will
own 55.4%, while the remaining 44.6% shares will be owned by
Vd2h shareholders in the new entity, Dish TV Videocon Limited.
Current Dish TV CMD, Jawahar Goel, will head the new
company as chairman and managing director, while Vd2h will
nominate two directors - one of whom will be vice chairman
and the other a deputy managing director of the company.

OTT in focusOTT mania seems to be taking over India as mobile proliferation
and bandwidth on three airwaves headed north. With 400-
million plus smartphones and a national seventy per cent
coverage projection of the country by 2017/18, OTT is set to
grow to a hundred players at 45-50 per cent annual growth.
A couple of recent reports on the media and entertainment
industry highlight OTT’s bright future in the country. According to
Deloitte Technology, Media and Telecommunications Predictions
2016 report, “Over-The-Top is likely to bring new dynamics in
digital media”. A few reasons why OTT will gain market share
in coming years are the three Cs—convenience, content and
control. “4G will bring the complete transformation of the current
television viewing experience and mark a shift in control from the
broadcaster to the consumer,” said the Deloitte report.
The use of smaller screens on personal devices will fuel ‘personal
escapism’ or watching content individually, with 45% of all
content consumed expected to be on the small screen by 2020,
as claimed by another report from consultants, EY. So in five
years, we may see a different world of media and entertainment
with OTT proving to be the technology of the future.
All the major operators, content houses and broadcasters have
thrown their hats into the OTT ring. Star; Zee; Viacom; Sun;
Balaji; Airtel; Vodafone; ETV and Eros have all set in motion a
definite OTT strategy for a piece of the pie.
India’s digitisation programmeThe Indian government and the court seem to have finally put
markers down on the ever-shifting deadlines of Digitisation Phase
III. The deadline for implementing Digital Addressable System
(DAS) in the phase III cities expired on 31 December 2015,
which was challenged on the grounds on non-availability of
set-top boxes and others by multiple local cable operators in
different state high courts.
In the recent order, as reported on 7 November 2016, Justice
Sanjeev Sachdeva of the Delhi High Court’s single bench has
over-ruled orders passed by various other High Courts re
the stay granted for extension of digitisation. The court also
directed the petitioners to run a scroll on their networks about
digitisation and switch off analogue signals within three weeks
i.e. by 24 November 2016.
“It’s a welcome move that the law is taking its own course and
this would be in favour of broadcasters as well as viewers.
Broadcasters would be able to increase revenues, while viewers
will get the power of choice,” said Kaushik Moitra, partner at the
boutique telecom and media law firm, TMT Law Practice.
VD Wadhwa, CEO of SITI Networks, said, “This is a very
important judgement as the Delhi High Court has dismissed the
nine cases, thus paving the way for digitisation. Not just in DAS
Phase III areas, this order will also clear the passage for timely
implementation of DAS Phase IV of digitisation.”
The Andhra Pradesh government has successfully set a global
standard of delivering triple play to the villages across Andhra
Pradesh in record time, paving the way for rural India to savour
the fruits of the emerging digital divide and also bridge the
digital divide.
Another interesting development was the view of all
stakeholders that digital growth would also mean that the
industry would need to protect itself against digital video
piracy and we saw global specialists, such as Friends MTS,
engaging across the eco-system and building best practises
for harnessing the revenues that the fragile digital world would
generate.
All this illustrates that India’s growth story is on track, in motion
and irreversible.

SCTE India is rising to the need for technician training to install, maintain and support quality cable networks in the country.
By Lt. Col. VC Khare, Founder Member, SCTE India
Mandatory
Cable Television in India is believed to have started some time
in 1977 with the extension of VCR displays in hotels. It then
graduated from wired extensions of satellite streams to viewer
homes, coupled with cable streaming of feature films as video
channels by cable operators.
The activity remained totally private, as it was sourced from
private funds. The screening of Gulf War and Satellite streams
of STAR TV in the early nineties was popular in India and led
to the proliferation of TV broadcasting as well as the popularity
of the wireline-delivered service.
At present, over 150 million cable homes in India are stated
to be contributing to these services, delivering over 300
programmes (not channels, as they are loosely referred to,
since several programmes in digital services are compressed
into one 7- or 8MHz RF channel in the 47-862MHz RF
spectrum).
The announcement of India’s Cable TV Networks Regulation
Act 1995 legalised the service, resulting in the emergence of
MSO (Multi-Service Operators), although in India they provide
only uni-directional television re-broadcast over HFC (Hybrid
Fibre Coaxial Cable) over wireline networks. The estimated
number of MSOs at present in India is about 6000.
The MSOs run headends feeding the service over optical
fibre to an interconnection near the cable operator. The O2E
(Optical to Electrical) converter (not strictly a node, since
the services are uni-directional i.e. without any return path
requirement) is the property and responsibility of the cable
operator (registered as the network operator and essentially

prohibited from performing any technical functions of a
headend). Coaxial cable is extended through amplifiers and
passives to subscriber premises and accessed through an
addressable Set-Top Box (STB).
MSOs, (totalling approximately 6000 headends), were
mandated to encode and encrypt all content transported from
their headend (strictly prohibiting any analogue transmission)
in encrypted, digitally addressable format. Addressability, in
simple terms, refers to enabling or disabling viewing through
the STB remotely and selectively from the headend through a
compatible SMS (Subscriber Management System).
At the subscriber end, it involved installing an STB,
conforming to Indian standards, for the subscriber to select
and view programmes of their choice only (authorised in the
addressable STB), be billed for the same and remit charges
for the service when billed. Over 150 million subscribers
are served through an estimated 60,000 cable operators,
employing over 240,000 technicians.
Training perspective of mandatory DAS India is a country with a very large population and lean
degrees of understanding of wireline/CATV technology and
the intricacies of legislation and compliance issues. Hence,
subscribers are not aware of DAS provisions. They are reliant
on technicians who, in turn, have not received any recognized/
structured training on the subject.
In the absence of any enforced easement rights, technician
philosophy is based upon a vaguely connected approach
without valid RoW (Right of Way). Most of them have little
understanding of Indian standards on EoL (End of Line)
specifications for connectivity, digital transmission parameters
for assured QoS (Quality of Service) and resultant QoE
(Quality of Experience). Paradoxically, these technicians were
expected to appraise the subscribers on the user perspective
on DAS when installing addressable STBs but could not do so
in the absence of any formal training.
The outcome, after four years of the mandate, is that
subscribers still do not understand DAS except for their
compulsion to install an STB, not always conforming to Indian
standards, and continue to pay a fixed monthly subscription
for watching more content with improved noise reduction on
their TV screens, thanks to digital transmission mandates.
India’s Prime Minister has conceived a ‘Digital India’ with 150
million cable homes (at present, uni-directional) to proliferate
broadband into homes and dilute the digital divide.
Potential for SCTE training in IndiaIn the absence of any organised training facilities for mandatory
DAS, the SCTE philosophy is very conducive to the Indian
environment. SCTE training modules already exist for:-
(a) Installers to follow recommended practices for installing
CPE (Customer Premises Equipment) i.e. STB, fixed line
telephones and broadband modems. This training is
deemed to confine itself to the in-house environment with
full training on subscriber relations and awareness as the
‘nearest and always available’ point of service restoration.
(b) Network engineers, proficient in the route from the
DEMARC point (telco terminology) all the way up to the
Headend/Central Office.
(c) Headend/Central Office engineers who understand
the lay-out of a designed Headend/Central office and

its ancillaries, Headend/Central Office management
system, the network management system, the subscriber
management system and affiliated customer care operating
procedures. Essentially, this covers daily checks on quality
and 99.99% reliability for all aspects of Headend/Central
Office operation.
Indian CATV networking is nearly 30 years old now and serves
over 150 million homes which are mandated to comply with
DAS provisions. The implementation remains confined to
estimating implementation from statistics on the number
of STBs sent out (and hence deemed installed) from MSO
warehouses. Therefore, there is a need to focus on training
needs, to upskill the workforce using SCTE training courses
and for quality indicators.
Increasing awareness and the resulting improvement in
service through the customisation of delivery platforms suits
the environment in India, where no academic qualification is
necessary for the personnel who deliver wireline content to
over 150 million subscribers.
Driving further membership to SCTE India is also essential
to impact the QoT (Quality of Training), inherent in the SCTE
philosophy, and to upskill those individuals expected to
maintain and install services at subscriber premises. Such a
skilled work force can quickly become an international asset.

As data demands continue to grow, scientists predict that
it’s only a matter of time before today’s telecommunications
networks reach capacity unless new technologies are
developed for transporting data. A new technique could help
avert this bandwidth crunch by allowing light-based optical
networks to carry more than one hundred times more data
than is possible with current technologies.
Laser light comes in many different shapes, or spatial modes.
However, today’s optical networks use just one spatial mode
to carry information, limiting the amount of data that can be
transmitted at one time. Researchers led by Andrew Forbes,
a professor at the University of Witwatersrand, South Africa,
have developed a technique known as spatial multiplexing
that re-shapes a laser beam into many spatial modes that can
each carry information.
In a paper presented at the OSA Laser Congress in Boston
on 3 November 2016, the researchers demonstrated
optical communication with more than 100 spatial modes
by combining their new spatial multiplexing approach with
Wavelength Division Multiplexing (WDM), which uses different
wavelengths of light to carry information.
“We created 35 spatial modes encoded in three different
wavelengths, producing 105 total modes,” said Carmelo
Rosales-Guzmán, research fellow and first author of the
paper. “Our new method might serve as the basis for future
communication technologies.”
The researchers demonstrated that their technique can
transmit data with 98 per cent efficiency in a laboratory free-
space optical network, which uses light to transmit information
over the air. The scientists say the approach should also work
in optical fibres, the basis for fibre-optic communications.
The new technique makes use of light with an orbital angular
momentum, which gives it a twisted, or helical, shape.
Different spatial modes can be created by varying the number
of twists, known as the azimuthal degrees of freedom. While
other scientists have been exploring the use of azimuthal
degrees of freedom for increasing bandwidth, recent research
showed that even though, in theory, the set of modes with
orbital angular momentum is infinite, in practice there aren’t
enough modes available to make significant improvements.
Forbes’ team solved this problem by using the azimuthal
degrees of freedom plus another variable, known as a radial
degree of freedom. Each azimuthal degree of freedom can
have, in theory, an infinite amount of radial degrees of freedom,
but there are practical limitations that restrict this number.
Because all the modes are orthogonal to each other, the
signals don’t get mixed up as they travel and can be separated
upon arrival at their destination. The researchers say that this
is the first time that two spatial degrees of freedom have been
used to optically encode information.
Key to this new approach is an optical device known as a
spatial light modulator. The researchers used one spatial light
modulator to shape the laser light into the various modes and
another to reverse the process on the receiving end.
“One of the advantages of our approach is that we only need a
single detector to demultiplex all the spatial modes to recover
all the information,” said Rosales-Guzmán. “This is faster than
other approaches for increasing bandwidth that need multiple
detectors.”
As a next step, the researchers are partnering with experts
in free-space communication to adapt their technique for
practical applications.
“We are working with a company in South Africa that already
makes a device that has the ability to use different spatial
modes for free space communication,” said Rosales-Guzmán.
“We are interested in trying to increase the bandwidth of their
device to four times what it is capable of now.”

A new Ovum report, jointly commissioned by nbn and BT, has
predicted that new ultra-fast copper technology, G.fast, will
be serving nearly 30 million subscriber homes and businesses
around the world by 2021. This is just four years after the first
commercial G.fast services are due to launch in 2017.
“In 2021, Ovum expects G.fast to be supporting nearly
29 million subscribers, representing 3% of the global fixed
broadband market,” said the Gigabit Networks' report. “As
an emerging technology, the growth in new G.fast subscribers
is expected to accelerate in each year, rising from 330,000 in
2017 to nearly 11.5 million in 2021.”
Nbn held its first G.fast trial in October 2015 and has been
conducting additional lab trials of XG.FAST in recent weeks.
It recently announced its intention to deploy Fibre-To-The-
Curb (FTTC) technology to approximately 700,000 premises
– a platform for potentially deploying both future G.fast and
XG.FAST services.
Ovum is forecasting particularly strong take-up of G.fast in
Europe, with operators including BT, Swisscom, Deutsche
Telekom, Telekom Austria and Proximus (Belgium) all planning
to deploy G.fast technology to deliver affordable ultrafast
connectivity quickly and cost-effectively.
“About 11% of broadband services in Western Europe may be
delivered via G.fast within five years, with a number of major
markets already including the technology in their upgrade
plans,” added the Gigabit Networks' report.
Openreach, BT’s local network division, is expected to be one
of the first operators in the world to launch commercial G.fast
services, with a launch expected during 2017. It is aiming to
make ultra-fast speeds available to 12 million premises in the
UK by the end of 2020 – using a mix of G.fast and Fibre-To-
The-Premises (FTTP) technologies.
Openreach is already working to conduct the largest G.fast
field trials in the world, delivering speeds of up to 330Mbps.
The company recently announced an extension to its pilot
which will see around 140,000 homes and businesses across
the country given access to G.fast by March 2017.
“Developed by Nokia Bell Labs, XG-FAST is targeting
throughput of up to 10Gbps over very short bonded copper
lines,” explained the report. ““This effectively positions XG-
FAST as a fibre extension solution that avoids the cost, and
often logistical challenges, of accessing the premises.”
Dennis Steiger, nbn's chief technology officer, said: “This
report shows the potential that G.fast has for delivering
ultra-fast broadband services in the global market. It is very
challenging to deliver fibre into every home. Having the option
to use G.fast in a Fibre-to-the-Building or Fibre-to-the-Curb
setting is a great option for any operator.”
Clive Selley, CEO of Openreach, added: “Our aim is to
make ultra-fast broadband available to 12 million homes
and businesses in the UK by the end of 2020, and we’re
embracing a mix of technologies with G.fast and FTTP to
achieve that. We have pioneered G.fast in our labs, driven
the global standards and have been working closely with our
communications provider customers on the trials, so we’re
very excited that it’s time to start rolling this technology out
nationwide. The great thing about G.fast is that allows us to
deliver affordable ultra-fast speeds to customers quickly and
at scale.”

FutureSource Consulting analyst, Michael Boreham, told
attendees at VRAR World in London recently that "we have
finally entered an age where VR can become a commercial
reality as the hardware and, more importantly, cost had
reached a tipping point".
However, Boreham told the audience in his session on’ Virtual
Reality – Niche or Reality’ that “content is a bit further away,
we are still in experimental mode”.
He said that, thanks to the recent launches in gaming
VR, “games are a bit closer than TV. But there is a lot of
experimentation in broadcast”.
Boreham explained that one of the major challenges to the true
uptake of VR was monetisation. “It is not cheap to produce this
content. Often content is quite short, so getting consumers
to pay is difficult. From a consumer point of view, it is more
accessible. The PS4 and others have helped here. There is a
lot to be done to raise awareness. But is there an appetite?
There is a challenge there in terms of raising appetite.”
Another factor, he told the audience, was awareness.
FutureSource research found that only 7% of UK consumers
had tried VR, compared with 5% and 4% respectively in
Germany and France. In the US, the figure stood at 8%.
“Many people, while aware of VR, haven’t experienced a truly
great VR experience yet,” he said. However, Boreham pointed
out that the number of 19 to 35-year-olds that had tried VR
was double the average.
“Retail channel is key here, to raise awareness,” he added,
especially with the number of consumer releases in gaming.
“The console space is beginning to get really interesting,” he
said.
FutureSource believes that, by 2020, total content revenue will
be in excess of US$ 6bn worldwide. This will be split 24% to
video and 76% to games. The gaming VR market, however,
at US$ 4.8bn is still only 2.5% of the overall gaming market.
Boreham believes that, in the shorter term, Pay-Per-View will
be the preferred way to monetise VR in sports, echoing the
early days of satellite TV. “In the short-term, it will be PPV
around key boxing matches or other sporting events that we
tap into on that basis”.
He also suggested that major TV or movie franchises might
also tap into VR. “This could include big studios or a tie-in to
gaming, as we’ve seen with Fantastic Beasts,” he explained.
“It might be bundled, so it might be a VR companion piece to
our BluRay of a film.”
The watershed for TV will be 2018, according to FutureSource,
when the technology and take-up will be large enough.

Scotland’s largest city is on the cusp of a ‘tech
boom’ that could directly result in a £107.5 million
per annum boost to its economy, according
to one of the country’s leading network and
communications firms.
Commencing construction this year, the 40km
multi-million-pound pure fibre investment will
make Glasgow Scotland’s third Gigabit City, with
connections expected to go live in early 2017.
Ricky Nicol, Chief Executive of Commsworld,
who has had an office in Glasgow for more
than 20 years, said: “Glasgow has had a hugely
positive resurgence of late that has included a
Glasgow set for tech boom with pure fibre infrastructure
China Mobile Shanghai Branch and Huawei have jointly
deployed what they dub ‘the world's first wideband 3D
Multiple-Input Multiple-Output (MIMO) site’. This is another
key milestone, after the first 3D MIMO solution was launched
in Shanghai in September 2015.
“This achievement marks a great leap forward for large-scale
commercial 3D MIMO technology and is the beginning of a
planned series of events outlined in the timetable for large-
bandwidth 5G evolution. This solution has significantly
improved single site capability in the 4G era indicated by a
5-fold increase, achieving 5-6 Gigabit capability of a single
site,” said Huawei.
The 3D MIMO solution is the primary wireless innovation
project that China Mobile has predominantly focused upon in
2016. This solution can greatly improve 4G network spectral
efficiency and can help to effectively handle any capacity
challenges encountered during rapid mobile development.
The solution is designed for the enhancement of coverage
and interference mitigation capabilities to meet specialised
coverage requirements (such as coverage of high-rise
buildings).
A single module supports activation of three carriers on
2.6GHz. A distributed network supports smooth evolution
to CloudRAN architecture and ensures that hardware is
sufficiently prepared and ready for 5G evolution. The average
spectral efficiency of cells can be improved three-fold. Along
with the rapid development of video services, the spectral
efficiency can be increased more than five-fold. Huawei’s in-
house-developed chips, new materials and new techniques
are used to provide compact and lighter site equipment.
“The efficient and rapid delivery of this solution is guaranteed
as only one optical fibre and one power cable are required to
ensure smooth deployment from an engineering perspective.
The adoption of the latest chips helps to provide processing
capabilities that are four-fold higher than that of the industry
standard, clearly demonstrating the performance advantages
inherent to 3D MIMO,” said Huawei.

The 150th anniversary of the first communication cables to
be laid across the Atlantic Ocean, connecting Europe with
the US, is being celebrated between now and 22 January
2017 in a free exhibition entitled ‘Victorians Decoded: Art and
Telegraphy’ at the City of London Corporation’s Guildhall Art
Gallery. Special curator talks on the exhibition will take place
on 15 December 2016 and 19 January 2017.
This exciting collaboration between Guildhall Art Gallery,
King’s College London, The Courtauld Institute of Art and
the Institute of Making at University College London explores
how the first telegraph cables connecting the continents
transformed communications with rare artefacts relating to
their use and manufacture.
This exhibition features four themed rooms (Distance,
Resistance, Transmission and Coding) featuring samples
of Victorian transatlantic cables, one-of-a-kind prototype
transmitters and devices developed by Victorian telegraphy
pioneer, Charles Wheatstone. ‘The Great Grammatizor’, a
special messaging machine to encourage the public to take
part in the exhibition, and paintings by prominent Victorian
artists will also be on display. The exhibition showcases
samples of cables used in early British and French transatlantic
telegraphs. These worked by sending electric signals down a
copper core formed of seven wires
It took nine years, four attempts and three cables until the
Victorians successfully installed two transatlantic telegraphs
from Valentia Island in Ireland to Newfoundland in Canada on
27 July 1866 and 7 September 1866.
The ability to send messages across continents in minutes
(approximately one minute for every eight words) for the first
time was a ‘moon landing moment’ for communications
and telegraphic engineering, and (similar to the internet in
recent decades) it sparked opportunities for businesses,
governments, military forces and the public that were
previously unimaginable.
“The cores of early submarine cables were too thin and
produced electrical effects that interfered with the sending
of signals. Charles Wheatstone and other scientists therefore
developed devices that amplified weak signals and improved
our understanding of how electricity behaves. On display at
the Guildhall Art Gallery is Wheatstone's own prototype of
the famous Wheatstone Bridge, a device used to discover an
unknown resistance from known ones, and a Resistance Box
that allowed engineers to create 'dummy' circuits of any length
and resistance for experimenting with and testing equipment,”
said the City of London Corporation.

Over the next five years, competition will intensify and new
strategic partnerships and business models will emerge, finds
Frost & Sullivan’s Digital Media team. The nascent Over-The-
Top (OTT) video market in India is growing as smartphone
penetration and 3G and 4G subscribers continue to increase
rapidly. The recent launch of Reliance Jio's affordable data
services and initiatives, such as Bharat Net, will continue to
drive down data service prices, boosting video consumption
over fixed and mobile broadband.
“It will be critical for market participants to gauge viewership
trends, price sensitivity and technical requirements while
offering their video services,” said Frost & Sullivan digital media
director, Vidya S Nath. “Pricing, data analytics, personalisation
and video quality will be crucial in defining the market leader in
the next five years.”
The ‘Over the Top (OTT) Video Market Update, India, 2016’
analysis is part of Frost & Sullivan’s Digital Media Growth
Partnership Service programme. India has over 300 million
Internet users and about a billion smartphone users. Millennials
and Gen Y comprise about a third of the population and are
driving viewership trends towards personalised content.
The country’s fragmented demography offers more than 20
types of audiences by major languages, creating tremendous
opportunity for content creators and producers.
The market is already crowded with about 25 market participants
that include telecom operators, Direct-to-Home (DTH) TV
providers, broadcasters and individual OTT providers. The
number of participants will grow further over the next two years.
“Even though the return on investment for OTT services providers is
slow and does not justify the business proposition in the short-
run, competition will spur all broadcasters to consider the OTT
business,” noted Research Analyst Aafia Bathool. “Exclusive
content at a competitive price with a sophisticated, user-friendly
interface is the way forward. To achieve this, the market will see
increasing strategic alliances among ecosystem players.”

As consumer need intensifies for access to faster Wi-Fi, an article
published in the Institution of Engineering and Technology’s
(IET) Electronics Letters journal reports how researchers from
Japan have increased the speed of Wi-Fi data transmission by
10 times the current rate, achieving a record 34Gbit/second at
a 500GHz range. This falls within the terahertz range, which is
approximately between 300GHz and 3THz.
Improving speed of wireless data transmission

The authors, from the Tokyo Institute of Technology, originally
published research exploring the direct intensity modulation
and wireless data transmission characteristics of terahertz-
oscillating resonant tunnelling (RTD) in 2012. The authors found
that while data transmission speeds were considerably faster
than the current Wi-Fi standard, the low cut-off frequency of the
modulation at just 1.5GHz meant that speed was limited to a
maximum 3Gbit/s.
Through continued research, the team has now reported that
speeds of up to 34Gbit/s can be achieved by reducing the
parasitic components of the RTD device which enabled a much
higher cut-off frequency of 15GHz. The team also improved
performance at room temperature and reduced the device's
size, meaning that using THz frequencies in small or mobile
devices is now a realistic option.
Commenting on the research, Naoto Oshimo, one of the authors
of the paper, said: “Using the improved device, an error-free
transmission up to a data rate of 22Gbit/s, and a transmission
with a bit error rate less than the forward error correction limit up
to 34Gbit/s, was achieved. The device performance is almost
sufficient for short-distance wireless communication such as
KIOSK downloads, which might be its first application.” Final
ranges will be up to 10 metres, allowing for use in home Wi-Fi.
The application of the terahertz range for wireless
communications has long been explored due to its potential
to provide significant bandwidth for very high data transfer.
Resonant-Tunnelling-Diodes (RTDs) are good candidates
for achieving these frequencies as they have the unusual
characteristic that the voltage across them can sometimes go
down as current is increased.
In a final comment, Oshima said: “Owing to the increase in data
traffic, the frequency used has been expanded for obtaining a
wider bandwidth. This, we hope, will lead to a proliferation in
THz wireless communication technology over the next decade.”

There is obvious current interest in how the UK will exit
the EU and the effect that this will have on the future
of the UK’s involvement in European and International
standards. The British Standards Institute (BSI) has
issued a statement for guidance and the following is a
précis of their views.
National level
BSI will continue to develop and publish British Standards.
No changes are anticipated to UK Committee activity in
this area.
European level
BSI maintains the UK membership of the three European
standardisation organisations: CEN, CENELEC and ETSI.
Membership of these organisations should continue
as normal; it will hopefully be ‘business as usual’ in all
aspects of BSI standards-making and publishing activity.
It is BSI’s ambition, on behalf of UK stakeholders, for the
UK to continue to participate in the European standards
system as a full member of CEN and CENELEC post-
‘Brexit’
31Vol. 38 No. 4 - November 2016 Issue
from the industry
It will hopefully be ‘business as usual’ in all aspects of BSI standards-making and publishing activity.
International level
UK membership of the two international standardisation
organisations, ISO and IEC, will be unaffected by an exit from
the EU. BSI is committed to representing the UK’s interests in
the creation of international standards that support innovation
and provide solutions to global challenges.
UK membership of CEN, CENELEC and ETSIMembership of CEN, CENELEC and ETSI has been essential
to the UK’s participation in international trade as a member of
the WTO and essential in fulfilling its obligations as a member
of the European Single Market.
UK membership and participation in ETSI should not change
significantly since ETSI membership is not limited to European
companies and organisations. However, on the UK leaving the
EU, there would be consequences for the UK’s eligibility to
participate in CEN and CENELEC. This impact will depend
on the political decisions made over future trade agreements.
A range of four options is considered below to illustrate the
impact:
1. The UK applies for membership of the European Free
Trade Association (EFTA) and then seeks to sign the
European Economic Area (EEA) agreement (like Norway
and Iceland)
or
2. The UK applies for membership of EFTA but remains
outside the EEA, negotiating bilateral trade agreements
with the EU (like Switzerland).
or
3. The UK relies on the World Trade Organisation Technical
Barriers to Trade (WTO TBT) Agreement to protect the UK
in international trade.
or
4. The UK negotiates bilateral trade agreements with the EU,
without being an EFTA member.
In the case of the first two options (1 and 2), it is anticipated that
BSI would retain membership of CEN and CENELEC without
challenge. BSI would meet both the membership requirements
of the CEN and CENELEC statutes and the criteria for
membership (ways of working). In these circumstances, the
impact would be minimal in terms of the UK’s membership
rights within CEN and CENELEC. However, there would be
impact in terms of relationships with partner countries and on
the ability of the UK’s NSB to influence regulatory policy at
European level
For options 3 and 4, BSI would need to argue for the
continuation of UK membership of CEN and CENELEC.
Continuing membership in these circumstances would
depend upon other CEN and CENELEC members agreeing
to change the statutes to create a category of membership
fitting the UK situation.
Arguments could include historical membership, economic
significance, commitment to and involvement in the system
and the difficulty of EU countries exporting to the UK having to
deal with a different standards regime in the UK. Acceptance
of these arguments would probably depend upon whether
the UK continued to commit to the adoption of all European
standards (on a voluntary basis as a non-member of the EU).
Summaryn BSI will continue to develop and publish British Standards.
n BSI’s membership of ETSI will not be affected as its rules
of membership are different from other EU standards
bodies.
n EU exit will not affect the UK’s membership of the two
main international standardisation organisations, ISO and
IEC.
n UK involvement in CEN and CENELEC may have to
change but it is BSI’s intention to maintain full participation
in European standards' development.

Cable operators have a growing opportunity to turn their strengths and advantages into new revenue streams.
Convert Speed,
The DOCSIS 3.1 era is in its early days, but the results so far
indicate that the new platform for hybrid fibre coax networks
is delivering on its promises, particularly when it comes
to producing Gigabit-class speeds alongside improved
bandwidth efficiency. This evolution to Gigabit-level broadband
speeds will eventually morph into new service options for
consumers and businesses.
Wireless operators are already investing heavily in 5G
networks, and this technology also presents an interesting
opportunity for the cable industry at both ends of the delivery
chain – either as a fronthaul to deliver service or as backhaul
that leverages the existing infrastructure. Cable operators will
have to decide how to proceed to find success.

Virtualization and Efficiency into RevenueBy Paul Hughes, Director of Strategy, Netcracker Technology
33Vol. 38 No. 4 - November 2016 Issue
from the industry
Monetising new business servicesCable operators have a growing opportunity to turn speed
into new revenue streams. The growth of 4K video and
High Dynamic Range (HDR) represent what’s next in video
quality and enable service options that should have higher
monetisable value, regardless of whether they are delivered
as part of a traditional cable bundle or as an Over-The-Top
service. MSOs believe that 4K and HDR support will be their
market advantages over competitors in attracting new higher-
end customers, so being able to deliver and monetise those
services should be a top priority.
The shift towards virtualization will bring new operational
efficiency advantages to MSOs, initially with the adoption of
virtual Customer Premises Equipment (vCPE) devices such
as set-top boxes that provide greater efficiency and cost
savings by shifting functionality from the box to the cloud. By
rendering the set-top box as more of an access point than
an intelligent device, MSOs can dramatically reduce the cost
of equipment in the home, in some cases by as much as 70-
per cent or more. Virtualization also shifts device management
to the cloud, allowing the MSO to manage devices remotely,
including troubleshooting, testing and remotely managing
problems, pushing software upgrades where necessary and
ultimately eliminating the need for costly truck rolls.
Virtual CPE (vCPE) benefits extend to the growing business
services market, especially for small and mid-sized
organisations. SMB-related business services, in particular,
represent a growing opportunity for most cable MSOs looking
to expand their customer base beyond the consumer market.
Comcast recently said that its business services unit was a
significant growth driver in 2015, with revenues increasing by
20 per cent compared to the previous year and an annual
revenue run rate of US$ 5 billion. The operator has also created
a new enterprise unit to focus on Fortune 1000 companies
and drive growth in this segment using targeted programmes
and offerings specific to these customers.
The operational benefits of vCPE are transformative, and
will greatly improve the way that MSOs manage both the
technology and the user. Virtualization will help to reduce
and simplify any customer interactions, reduce innovation
cycles for developing new services and reduce time to market
for new features and applications. Service interruptions or
problems can be addressed and corrected more proactively,
and cable customers will realize the benefits of new services
that are activated without the need for truck rolls or CPE
replacements. Simplifying these processes becomes almost a
guarantee for an improved customer experience
An evolutionary shift for cable MSOsVirtualization may be revolutionary to cable operators, but the
shift will be evolutionary. MSOs should build a business case
that highlights the operational cost and performance benefits
and amortizes the costs of shifting from the physical to virtual
infrastructure. They should see a rapid return on investment in
the elimination of truck rolls, reduction in home tech visits and
longer usage cycles of on-premises, upgradeable hardware
in the home or office. These changes to the operating model
for residential service delivery are the first step in laying the
foundation for a new kind of business.
Cable MSOs must also look for ways to improve the
customer experience through driving greater process
efficiencies. The elimination of unnecessary service costs
is of paramount importance to any MSO. Truck rolls for
cable service-related installs and repairs rank as one of the
most costly components of the cable service, and the timely
performance of a service appointment is intrinsically linked
to customer satisfaction. Appointment delays become a
source of frustration for customers, and sometimes simple
corrections or resets of customer premises equipment
become unnecessary high-cost components over the
lifetime of the customer relationship.
In an ideal scenario, technical support services would be
limited to initial installations, customer premises equipment
(i.e. set top box) failures or disconnects, and every other
Paul Hughes, Director of Strategy, Netcracker Technology
34 Vol. 38 No. 4 - November 2016 Issue
from the industry
interaction with the customer would be simple, seamless and
efficient.
As delivery technologies evolve, so must the MSOs’ order-
to-cash strategies. The industry has to navigate between the
legacy environment, in which it has poured billions of dollars,
and prepare itself for newer greenfield services.
As the majority of MSOs in the US outsource much of their
back-office processes to third-party technology suppliers,
now is the time to align expectations for new service revenues
with the needs and requirements in the back office. With the
increased adoption of virtualization at the CPE level, the core
service delivery functions of compute, storage, encryption
and packaging move to the cloud, giving significant flexibility
around service innovation and device lifecycle. MSOs must
map this flexibility to the abilities of back office systems to
manage:
n Provisioning and billing of traditional “legacy” video service
bundles and higher value 4K and HDR services when
available, on-demand video streaming and multi-device
business support models.
n Revenue settlement between MSO and OTT providers,
whereby the MSO provides instant access to the customer
and the OTT provider complements existing offerings with
unique and highly monetisable content or related services.
n Next-generation, non-traditional but data-intensive service
offerings that can generate new revenue streams such
as IoT, smart homes and automation, and B2B services.
A huge new revenue-generation opportunity exists for
the cable industry, but requires substantial upgrades of
existing back office systems and processes, including
identification, authentication, device onboarding and
management, data aggregation and normalization.
The cable advantageAs the industry adopts virtualization and looks to the future,
cable operators can take comfort in their huge advantage
with their local infrastructure. Virtualization and back-office
transformation are two significant technology shifts that
can help MSOs to capitalise on the growth in business
services. By embracing virtualization, cable operators have
more opportunities to deliver a variety of enterprise-specific
offerings, including cloud-based SMB apps stores, security
and data centre services.
However, telco service providers, with their deep pockets,
deep fibre and 5G, will be competitive too. First and foremost,
MSOs should ready themselves for more flexible monetisation,
but the initial focus should be on monetisation flexibility of
today’s available speeds. The evolution towards Gigabit levels
of bandwidth can only benefit an MSO if back-office processes
are first aligned around current services. So now is the time
to prepare and ensure that the technology roadmap is ready.

We review this year’s IBC conference and exhibition in Amsterdam and chronicle the reactions of SCTE’s IBC bursary winners.
An Eye on IBCBy Sara Waddington, Managing Editor, SCTE
from the industry
From a record attendance to the first standing ovation for an
award winner, IBC2016 in Amsterdam this September was
a great success. The headline attendance (not registration)
figure for IBC2016 was 55,796 people from over 160 countries
across the six days of the conference and exhibition.
IBC is a key annual event for professionals engaged in the
creation, management and delivery of entertainment and
news content worldwide. It combines a highly respected and
peer-reviewed conference with an exhibition that provides
more than 1,800 leading suppliers of the latest electronic
media technology with strong networking opportunities.
The exhibition featured over 1,800 exhibitors, including 249
companies at their first IBC. One important addition to the
feature areas in the exhibition was the IBC IP Interoperability
Zone, an initiative to push forward open standards in new
connectivity. Supported by AIMS and the IABM and working
with AES, AMWA, the EBU, SMPTE and VSF, IBC created
a dedicated exhibit which demonstrated verified technical

from the industry
progress in IP interoperability and featured the award-
winning VRT-EBU LiveIP studio, which was used for IBCTV’s
production at this year’s show.
The conference in focusReflecting the state of the industry, the conference took
transformation as its theme. That was also reflected in the
IBC Leaders’ Summit, the behind-closed-doors programme
for 150 C-level Executives. The conference programme
was reorganised this year to provide a clearer, more readily
navigated structure and a focus on the content value chain.
Across the five days, 435 speakers took part in more than
100 sessions.
The IBC Best Conference Paper Award is presented to the
authors of the paper which presents important new research
in a clear and engaging way. This year, it went to Erik Stare
of Teracom in Stockholm, Dr. Jordi Giménez of Universitat
Politècnica de València in Spain and Dr. Peter Klenner of
Panasonic Europe, based in Frankfurt, for their paper ‘WIB – a
new system concept for digital terrestrial television’.
“Our choice this year was for a paper which tackles a subject
some may have thought close to end of life, but actually
revitalises the whole subject of terrestrial broadcasting,” said
Dr. Nick Lodge, Chair, IBC Technical Papers' Committee.
“What these researchers propose is a way to achieve higher
digital bandwidth, an incredibly efficient use of spectrum and
a huge reduction in power consumption. This is genuinely
ground-breaking work, turning conventional wisdom on its
head – a very exciting paper indeed.”
One of the most popular conference sessions featured Ang
Lee discussing, and demonstrating, how he has employed
remarkable technology to create a strong sense of engagement
in his new movie, 'Billy Lynn’s Long Halftime Walk'. Specially
created for IBC, the clip from the forthcoming movie was
projected at 120 frames per second in 4K 3D, using Christie’s
6P laser projection and Dolby Atmos.
IBC awardsAng Lee was also the recipient this year of IBC’s highest
award, the International Honour for Excellence. The audience
also saw the most unusual acceptance speech yet at an IBC
Awards Ceremony. NASA received the Judges’ Prize, and
IBC was thanked in a special message from astronaut Kate
Rubins in the International Space Station.
The LiveIP Studio project took the award for content creation,
with trophies presented both to the EBU and the host of the
project, Flemish broadcaster VRT. The judges admired the
way the project had taken a practical approach to using IP
for live production, involving a large number of vendors and
solving the interoperability issues.
The exhibition featured over 1,800 exhibitors, including 249 companies at their first IBC.
Across the five days, 435 speakers took part in more than 100 sessions.

from the industry
Two of the entries in content management were around reality
television. Endemol Shine Germany took the trophy for its
production management on Wild Island, which split the post
between the location – two islands off the coast of central
America – and the company’s base in Cologne.
The trophy for content delivery was awarded to BT Sport. It
launched an Ultra HD channel last year, and the audience at
the IBC Awards ceremony was treated to some stunning 4k
sports footage on its screen.
The Auditorium was once again converted into the IBC Big
Screen and, as well as the awards and Ang Lee’s keynote
presentation, it was also the venue for two hugely popular
movie screenings, both using Dolby Vision HDR and Dolby
Atmos. These were The Jungle Book in 3D courtesy of the
Walt Disney Company and the harrowing 19th century saga,
The Revenant, provided by 20th Century Fox.
“The continuing success of IBC is down to the hard work of a
lot of people, staging an event that is relevant and engaging
across the whole of our transforming industry,” concluded
Michael Crimp, IBC CEO. “We continue to evolve, and I am
confident that next year’s IBC – our 50th anniversary edition
– will be even better. I look forward to welcoming you back to
Amsterdam from 14 to 19 September 2017.”

of IBC below and, if any SCTE members have not yet applied for
an SCTE bursary in 2017, then their thoughts and comments
may encourage other members to apply next year.
Sean GodfreyPrincipal Engineer, Access Engineering, Virgin Media, UK.
Reading last year’s bursary winner reports
in November’s issue of Broadband
Journal, I felt compelled to submit an
application to the SCTE for this year’s
IBC exhibition in Amsterdam. Thankfully,
I was one of the four lucky winners. Firstly, a big thanks to the
SCTE team for giving me the opportunity to attend the 5-day
event, arranging silver passes, lovely nearby accommodation
and for making us all most welcome throughout the event.
I’d last attended the event way back in the mid ‘90s and knew
a bit of pre-planning was in order. Once registered on the
IBC website, you can add exhibitors to your personal profile,
arrange meetings in advance and plan the presentations to
attend, rather than leaving everything until you turn up and
being somewhat overwhelmed. The personalised floor plan
download proved most useful.
An early Friday morning flight from Birmingham and a two-
stop train journey from Schiphol airport to the RAI Exhibition
centre were straightforward, as somehow I’d missed the
availability of the dedicated shuttle buses. After a few redirects

Left: SCTE Executive Committee members on the Partners Village booth at IBC

to the many busy Registration desks, I presented my QR
code and received a handy IBC bag and welcome pack,
plus an invitation to the IBC party on the first evening and a
complimentary Travelcard for buses and trams to use around
Amsterdam during my stay.
Now covering fourteen halls, plus further outdoor areas with
“the beach” and its busy bar alongside the canal and the
latest OB trucks out front, and with around 55,500 visitors
descending on the city, it was the sheer scale of the event that
struck me most. Bringing together the players in TV, Telcos, IT
and beyond, the event dictated that sturdy shoes and plenty
of walking were in order.
After meeting the SCTE team at the Partners Village booth,
I picked up a floorplan for when my Ipad battery ran out (tip:
don’t forget your travel adaptor). Day one was spent visiting
stands on my favourites’ list to get my bearings.
Halls are helpfully laid out by theme: Creation, Management
and Delivery. IBC is a great showcase for everything
‘broadcast’ and having previously worked in TV production
before my cable days, I found plenty to see and bring me
up to speed on, with the mass move to IP now for content/
production as well as distribution. Virtual Reality/AR was
evidently gaining momentum now with lots of companies,
and it was very interesting from a personal viewpoint to sit
in on a couple of demos by Adobe to understand a bit more
about how VR/360 videos are shot and edited by stitching
multiviews together, before being published for headset use
or on social media/YouTube etc.
It was quite an eye-opener visiting existing suppliers to our own
company to realise how much wider their range of products
and services span beyond those that we may just know as
engineers. There were other random stands where exhibitors
explained previous dealings or trials with our company that,
again, we’d never normally know about, and gave me some
new insights into my own company. By the time of the IBC
Olympics-themed party at 6:30pm, I was ready for a few
drinks and some welcome food with the SCTE team. A short
tram ride (remember: clock in and out) took us down to the
hotel for a much needed recharge of batteries.
On day two, I joined another VM colleague and bursary
winner, Steve. Saturday included a look around the latest
camera, lighting vision switching and data storage products
with tape long consigned to Sony’s museum-type displays.
Bridge Technologies demonstrated its latest add-ons for
VBC/probes, its impressive Remote Data Wall and SDI to IP
products, and kindly invited us to one of its evening canal tours
on the Sunday evening. Liberty Global’s stand was a chance
to see some of our partner companies’ customer offerings.
To break up the walking, there were some thought-provoking
talks in the Content Everywhere and Technology in Action
sections. One discussed the move of distribution and now
production to an IP base, speeding up the delivery of new
content and the need for traditional expertise to adapt to the
new skills now required. Issues over the aligning of standards
to deliver the envisaged interoperability are still being
addressed. Another talk on OTT niche sports for delivery gave
examples of obstacles encountered and changing business
models, depending upon target markets, and showed that
the ‘one size fits all’ approach no longer applies. Any talks
that were missed were able to be viewed on screens around
the halls or on the IBC website. The entire event was linked
with an on-site IP-based production centre, using separate IP
studio, control rooms etc. spread over the site, to show and
capture everything going on, on “IBCTV”.
An evening in the City hopping on the no.4 tram to experience
the sights, sounds and aromas of Amsterdam had to be
included as part of the overall IBC experience.

A later start on Sunday took us to Cisco’s impressive stand for
a Proactive Network Maintenance demo, and Tivo showed us
the next version of Hydra stb UI which got a big “thumbs up”.
The “Hackfest” competition was interesting to keep up with
over the weekend, with several teams having just 36 hours to
devise innovative ways of improving the future for either living
room entertainment, the education/classroom experience or
viewers engagement in sports, with the final big prize winners
using facial recognition to feedback to tutors in real-time
whether students are coping or struggling with topics being
taught.
On day four, I took in demos by Agama technologies on its
end-to-end monitoring and assurance solutions which was
the first opportunity I’d had to actually see it in action.
The SCTE Benelux lecture meeting in the Forum Lounge
Theatre covered interesting topics around The IP Invasion,
including Globtel discussing how it can extend access
networks wirelessly to rural areas. Axon’s CTO opined
on making the best moves from SDI to Ethernet from a
broadcaster’s requirements and evolving standards, and
LGI's Director of DOCSIS Engineering gave an insight into the
access network evolution strategy to 2020. The evening saw
the SCTE team and its bursary winners enjoy a fantastic meal
at The Oceania restaurant, close to the RAI.
Day five was a noticeably quieter last day and much easier to
get around to talk to people, taking the opportunity to discuss
PNM with Skyline and check out the latest in Dataminer’s
orchestration, dashboards and DOCSIS 3.1 capabilities. I took
a final look around the OB trucks outside with stunning 4K/
HDR rigs, and some very impressive slide-out workspaces,
before returning to SCTE base for lunch, thanks and goodbyes
to Bev and the team.
All in all, a great opportunity for me to attend IBC and I
would certainly recommend applying for an SCTE bursary, in
particular for anyone who normally wouldn’t get the chance
to go.

The SCTE Benelux lecture meeting, with its theme of ‘The
IP Invasion Taking Over Our Distribution Networks?", was
really rich in terms of the content and subjects which were
discussed. It was interesting to uncover trends in next-
generation telecommunications platforms as well as Ethernet
taking over the future backbone on live broadcast industry
and ways to adapt to it.
In general, it was a great professional and social experience!
I would like to thank the SCTE for its bursary opportunity and
for hosting me at the bursary winner dinner in Amsterdam.
Dhurata PrapashticaTelecoms Engineer, IPKO Telecommunications, Kosovo
First of all, I would like to thank the SCTE
for choosing me as a bursary winner.
I really enjoyed IBC - it was a great
experience for me! It was also the first
time that I had ever attended an exhibition
and conference outside my country. I really appreciated the
chance to visit IBC 2016 and see the technology that I have
read about in action for the first time.
The 5-day exhibition was enough time for me to visit all the
halls and watch some of the conference sessions. There was
so much to see and to learn, getting in touch with vendors
and industry professionals as well as seeing the products
displayed. I found the Feature Areas, which tied into the IBC
conference running alongside the exhibition, very interesting.
The Future Zone was very popular when I explored the show
- exhibitors were displaying cutting-edge prototypes and
projects, 8KTV, fun VR headsets and holographic displays
which were stunning. I really enjoyed the time I spent at IBC.
It was a great experience for me - all moments for me were
“wow” moments. I would especially like to thank Beverley for
being so kind to us and taking care of us during the show.
Stephen HardingSenior Engineer, Virgin Media, UK
I work for Keith Holland in Virgin Media,
assisting him to type approve new test
equipment, maintain our existing test
equipment and keep in contact with
our suppliers. This year, I applied to the
SCTE for a bursary to enable me to
attend the IBC exhibition in Amsterdam. This covers all travel,
accommodation and entrance to the IBC exhibition/conference.
I spent some time planning before setting off on my trip as
there were over 1700 companies attending from around the
world across the various halls of the show. The IBC app was
an essential tool to help with keeping a log of who you wished
to visit and where you had already been. The map on the app
was also pretty handy for navigation.
I was interested to see the latest technology involved in
the creation and delivery of entertainment as well as the
technologies involved in monitoring the quality of streams.
Safe to say that I was not disappointed with the scale and
effort that the manufacturers who attend the IBC exhibition
put into their booths. You could try your hand at being a
cameraman with the latest 4k cameras - once everything was
recorded, you could visit the Adobe booth and see the many
techniques for video manipulation and some incredible effects
as well as seeing how the IKEA “Come Home to Play” advert
was created.
I attended many guest speaker sessions which were held on
various booths as you walked around. One of the hot topics
was the discussion around the transfer over to IP for the entire
broadcast path from video camera to customer premises
equipment. There were many demonstrations of the latest
technologies. When I visited the ARRIS booth, the E6000
CMTS was on show with a download speed via a cable
modem of 1500 Megabits/second and an upload of 314-
Megabits/second. The outdoor broadcasting HGVs, outdoor
broadcasting vans and an electric helicopter fitted with a 4K
camera were also on display.
Skyline Communications and Cisco spent time taking me
through Proactive Network Maintenance (PNM) solutions.
These enable targeted fault resolution before any cable
customers see a degradation of services. Several booths
were targeting an improved WiFi experience inside the home

as this is a common complaint from customers. Intel had an
interesting feature on its latest WiFi chip, WAV500, which
promises extended reach inside customer properties for an
improved customer experience.
The SCTE Benelux Lecture featured speakers discussing “The
IP invasion Taking Over Distribution Networks”. It looks like
an interesting few years in the cable industry as we make the
transition to a purely IP delivery of content.
IBC really was an amazing exhibition where I gained vast
amounts of knowledge on image recording, manipulation and
broadcasting. It certainly opened my eyes to the vast amount
of work and technology that goes on behind the scenes.
Thank you to the entire SCTE team for making me so welcome
and I would encourage everyone to apply for one of the many
bursaries available. They really are valuable experiences.

An Update on the Human Visual System
According to the latest industry research1, online video will
be responsible for four-fifths of global internet traffic by 2019.
Faced with delivering an ever-increasing number of video
streams, Over the Top (OTT) content providers and Pay-TV
operators are finding it challenging to provide consistent, high-
quality video experiences on every device while keeping capital
and operational costs low. This is partly because traditional
approaches to assessing video quality in an objective manner
are limited.
Measuring the video quality of encoded content is a subject
that has been discussed by experts for decades without an
agreement being reached on the subject. Traditional methods
were based on mathematical calculation of the image
distortion. These methods were proved to be inaccurate.
Objective video quality measurement is complicated. Its
primary goal is to calculate video quality as it is seen by the
Human Visual System (HVS). However, everyone perceives

technical
video quality differently. The visual system is not the same for
each person, and our sensitivity level to different aspects of
the video is not identical. Moreover, the understanding of how
human beings perceive visual information is not complete.
This situation is further complicated by the multi-dimensional
complexity that is involved in video scenes.
This article provides a comprehensive overview of the history
of objective video quality measurement, touching on the
current methods used as well as new research into the HVS
that enables operators to deliver more consistent, superior
video quality.
Common methods of video quality measurementFor many years, Picture Signal-to-Noise Ratio (PSNR) has
been the most common method to measure video quality,
despite the fact that many other new and improved methods
are available. PSNR is a method that mathematically calculates
the distortion of each pixel in the image. This method
completely ignores the impact of the surrounding pixels, the
complete image and the video scene information. We will
discuss, later in this article, the impact of the surrounding
pixels on the measured distortion as it appears to the HVS.
Since PSNR does not take into account any masking effects
imposed by the surrounding pixels, distortion is miscalculated
in different scenes. For example, PSNR overestimates
distortion when the surrounding area is spatially active and
underestimates distortion when the surrounding area has low
spatial activity. (See Figure 1 below.)
In Figure 1, images (a) and (b) have the same PSNR score.2
However, PSNR underestimates distortion in low spatial
activity areas; it calculates low distortion for the dotted area in
the sky, which is actually a very visible distortion.
In 2004, Structural Similarity (SSIM) was introduced, offering a
better video quality measurement than PSNR. A key element
of the HVS is to identify shapes and structures in the image.
The HVS is less sensitive to the details of image pixels and
more sensitive to the shapes of the objects and details of the
image.
Leveraging its higher sensitivity to structure, which in turn
relates to shapes, SSIM is able to achieve a more accurate
video quality measurement compared with PSNR. SSIM
independently measures structural and non-structural
distortion. While differently weighting the structural and non-
structural distortion, the correct balance can be achieved.
SSIM takes into account three elements of distortion: average
luminance, average contrast and structure/texture similarity.
Mathematically, the latter two components combined are

technical
equal to the PSNR measurement, normalised by the amount
of activity in the picture or measured area. This normalisation
is what helps SSIM to be more accurate than PSNR, as higher
spatial activity increases the masking of the distortion.3
While SSIM is an improved video quality measurement
compared with PSNR, it still has many limitations, an example
of which is shown in Figure 2 above.
Next-generation video quality assessmentUltimately, none of the existing traditional techniques for video
quality assessment measure distortion accurately, limiting the
capabilities of modern day compression systems. In the past,
there have been trials to build a video encoder that utilises
the feedback of video quality measurement to improve the
encoding decisions. Those attempts have been relatively
unsuccessful. Effectively assessing video quality requires
going beyond distortion measurement and taking into account
the HVS.
While SSIM made progress on measuring video quality, it is still
merely a distortion measurement that utilises spatial activity,
masking what actually characterises the HVS. The advantage
of SSIM is its simplicity and low computation requirements,
but it falls short of achieving optimal compression.
Some of the properties of the HVS that are important for
creating an accurate video quality measurement model
include:
n Contrast Distortion: The HVS is more sensitive to changes
in contrast as opposed to luminance level. When measuring
distortion, this needs to be taken into consideration. The
light information entering the lens in our eyes is received by
an array of rods and cones that are laid along the retina. The
rods and cones measure light intensity in different visible
wavelength and transmit this measurement using neurons
to one or more ganglion cells.
In Figure 3, a model of a ganglion cell that creates
a Receptive Field (RF) is shown. The RF is fed by light
receptive information that is generated by a group of rods
and cones. The first type of RF, shown in Figure 3A, is
called “off centre”. Its highest response is when the
centre is not exposed to light and the surrounding area is
exposed to light. The other type of RF is called “on centre”
and is shown in Figure 3B. Its highest response is when
the centre is exposed to light and the surrounding area is
not exposed to light.
The mechanism that responds well to transitions between
lighted and non-lit areas is the main reason that our visual
system is sensitive to contrast and less sensitive to pure light.
Note: video compression standards are compressing the
light level (luminance) information and not the contrast level.
n Spatial Frequency: The HVS model uses spatial
frequencies to measure visual information. The receptive
fields shown in Figure 3 exist in a different physical

technical
dimension. Each physical dimension corresponds to a
specific spatial frequency. The plurality of receptive fields of a
certain dimension results in higher contrast sensitivity to the
related spatial frequency. There are many existing models
that explain the response of the HVS to the light spatial
frequencies. Figure 4 below shows the Barten model.
Figure 4 shows that HVS responds differently to each spatial
frequency. The highest sensitivity is to contrast information
at ~ 4 cpd. The diagram also depicts that sensitivity goes
down to zero very quickly for high frequency. Sensitivity
decreases for lower frequencies, but does not completely
disappear.
n Pixel Information: All of the pixel information in an image
creates different types of masking on each of the pixels
where distortion is measured. The plurality of certain
information in an image reduces the sensitivity to each
occurrence of the same information. Pixel information
is characterised by its contrast, orientation and spatial
frequency. Furthermore, the plurality of the total information
in an image reduces the ability to detect the distortion in
an image. It is a common practice of video encoders to
increase the level of compression in images that contain
more information.
n Sequence Change: Video is a sequence of images.
When the video is changing across the images that
compose the video scene, the sensitivity to the distortion
might increase or decrease depending upon the type
and amount of changes. Taking into account the spatio-
temporal Contrast Sensitivity Function (CSF), we can more
accurately present the sensitivity to each pixel distortion
by considering the amount of their changes over time.
By weighing the importance of these sensitivities against less
relevant elements in a video frame, it’s possible to measure
which distortion is visible to the visual system and which is not.
Correct measurement of visible distortion allows the encoder
to determine the highest level of compression of each pixel,
image and video scene to achieve the desired video quality.
This balance between video quality and bandwidth is beyond
the capabilities of competing encoding techniques, such as
CBR or CVBR encoding.
Harmonic has spent extensive R&D resources on this area
and reached the conclusion that taking into account the HVS
is not enough to achieve true constant quality. While science
has made great progress in understanding the HVS, there are
still some pieces that are not known. The challenge is building
a video quality optimisation model that is complete and
consistent enough to drive reliable video encoder decisions.
To use video quality measurement as a built-in feedback to
the encoding decisions, there cannot be any room for error.
After years of continuous testing with a group of ‘golden eyes’, we
have identified the places where the video quality measurement
model does not behave accurately during subjective testing.
Whenever the model is found to be inaccurate enough to
calculate the video quality of a specific scene, it is refined until
the accurate measurement is reached. The result of this long
and intensive effort is a highly intelligent and accurate algorithm
that understands how to measure video quality independent of
the scene type and the video details.
Applying accurate video quality measurement to compressionClearly, accuracy is key when it comes to objectively measuring
video quality. When the algorithm described here is applied to
video compression, content providers and Pay-TV operators
can deliver consistent, high-quality video experiences at low
bitrates. The workflow is described below:
n Step 1: The video encoder looks to achieve best
compression and maximise video quality based upon the
available bandwidth.
Figure 4. Barten model for contrast sensitivity as a function of spatial frequency
Clearly, accuracy is key when it comes to objectively measuring video quality
48 Vol. 38 No. 4 - November 2016 Issue
technical
n Step 2: The amount of the video compression is
determined by the rate controller based upon a model
that predicts the number of bits that the compression will
create, given the measured video characteristics.
n Step 3: How much video compression is applied is a
good predictor of the compressed video quality. However,
this prediction is inaccurate.
n Step 4: Adding a measurement for video quality accuracy
brings huge value to the equation. The video encoder is
tuned to avoid video quality problems. Without accurate
feedback, it must rely on safety margins to avoid generating
bad video quality. These margins are relatively large.
ConclusionIn recent years, video encoders have transitioned from hardware
to software due to the availability of high-performance CPUs
that enable more flexibility in algorithm development at a cost
of ownership which is lower than hardware-based solutions,
accelerating the rate of video compression improvement. The
use of advancements in HVS research described in this article
are a result of such a technology shift. It is now possible to
implement much more demanding video quality measurement
methods than SSIM with a fraction of the CPU power available.
At Harmonic, we’ve identified a new way to determine the
target video rates for the different video profiles in an ABR
deployment. Our video quality measurement approach can
also be applied to broadcast services. Extensive testing
shows that providing operators with a scalable real-time video
compression optimisation solution that leverages the HVS is
proved to boost compression efficiency by 50 per cent, while
preserving video quality targets.
When this video optimisation solution is used in the real world,
viewers can watch pristine video on their device of choice —
even over constrained OTT/ABR networks. As video quality
goes up, subscribers are happier and spend more time
watching, improving monetisation opportunities for content
providers and operators.

US Lessons Learned:By leveraging the network and user behaviour knowledge with cost-effective, cloud-based tools and solutions, European providers are in a unique position to not only provide an optimal user experience but actually monetise the market expansion.
By OpenVaultOTT, Data Usage Growth and Monetisation Results
technical
IntroductionIn the United States, demand for Over The Top (OTT) video is at
an all-time high with no signs of slowing down. In a culture that
values and expects the delivery of massive amounts of content
at anytime, anywhere and on any device, the demand for OTT
content will continue to expand for the foreseeable future. In
fact, industry experts predict that OTT video will and ultimately
become a mainstream method for viewing video content. The
“TV Anywhere” dynamic is a current expectation, regardless of
age or geography.
For example, in a recent study conducted by MTM, an
independent London-based research and strategy group,
domestic (US) premium OTT revenues are expected to grow
from US$ 4bn in 2014 to between US$ 8-12bn in 2018.
Niche services, complementing more generalist Pay-TV or
OTT offerings, are also expected to proliferate with up to 15-
20 new specialist OTT providers acquiring 100,000 or more
paying subscribers by 2018, with even more attracting smaller
numbers of subscribers.
Over the Top meets 4KAs OTT video consumption ramps up, consumer behaviour
and technology will continue to expand and evolve accordingly.
To keep pace with and, more importantly, optimise the ever-
expanding OTT universe, the industry must anticipate market
changes, overcome technical challenges and create flexible
business models that monetise new opportunities that assure
both a quality experience for the subscriber and profitability
for the operator.
As expected, the emergence of OTT in Europe is following
a similar path to the US experience and, despite regulatory
issues and technology challenges, the European OTT market
is also expected to grow exponentially and present great
business opportunities over the course of the next few years
in particular.
51Vol. 38 No. 4 - November 2016 Issue
technical
However, for Europe to experience the same success as
the US OTT market, it is critical to understand subscribers’
high-speed data usage behaviours. As evidenced in the US,
a granular understanding will allow providers to make optimal
business decisions about their future broadband offerings.
The US experienceAccording to the MTM study, the US premium OTT market
has seen strong growth over the past years, largely driven
by Netflix, You Tube, Amazon and Hulu. In 2014, the market
was worth US$ 4bn, having grown at a CAGR of 36%
between 2011 and 2014. By the close of 2014, 40.3% of
US TV households were subscribing to at least one premium
OTT service. However, SVOD revenues, around US$ 4bn,
comprised only a relatively small share of the wider TV and
video market, estimated at approximately US$ 185bn in 2014.
The rapid growth of premium OTT services in the US market has
been due to a number of factors, including wide availability of
broadband infrastructure; consumer demand and willingness
to pay for content; scale and wealth of the US market; the fact
that the US is a leader in media, entertainment and technology
and Netflix’s domestic success, which stimulates overall
interest and investment in the OTT market.
Successful operators, programmers, service providers
and broadcasters in the United States who recognise the
revenue potential of these market changes and OTT growth
have adjusted their business models accordingly. However,
to monetise these new opportunities, several factors must
first be addressed to ensure this transformative success.
Firstly, consumers' new viewing habits and high-speed
data demands present not only technical issues, such as
network congestion, but also pricing/budget challenges
and customer satisfaction concerns. Therefore, many
independent broadband providers have begun offering cost-
effective solutions that respond to consumers’ evolving
streaming behaviours, offer friendly data usage plans and

technical
flexible pricing models and yet do not require large capital
investment into the network infrastructure.
A US case study The challenge
In a recent industry study of the effect of live sports
streaming on High-Speed Data (HSD) networks, broadband
management company OpenVault reported that there was an
average increase of nearly 20% in data consumption across
its global customer base during a live stream of a Sunday NFL
game, compared to normal Sunday usage.
This finding supports the idea that as more events are
streamed live onto more household devices, subscribers will
need to upgrade their service/increase their speeds to support
the additional bandwidth requirements. For operators, this
data growth means a necessary evolution across the board,
including technical infrastructure to innovative product and
programming delivery.
To be successful during this industry revolution, operators
must make informed decisions and, to do so, they must first
understand subscriber HSD usage behaviours to develop
new product offerings.
In addition, operators must effectively communicate with
subscribers with targeted messaging to enhance their user
experience. Lastly, operators must consider aligning this
growing demand for data with growing revenues through
usage-based billing and/or a well-defined upgrade strategy.
To improve visibility into their networks and to automate
management functions to proactively handle congestion,
forecast network requirements and communicate with
subscribers, a US-based Tier Two provider deployed the multi-
purpose, cloud-based OpenVault platform that is designed to
bring network, data usage and marketing data together in a
way that has never been done before.
In this way, OpenVault collects data from multiple sources
and provides both dashboards and specific solutions, which
allows operators to easily see where improvements can be
made, and the impact of those decisions across multiple
disciplines. This powerful information, combined with deep
analytics and real solutions, helps the provider to not only
monetise the high-speed data usage on their networks but,
equally importantly, to better serve and enhance the user
experience through cost-effective integration of subscriber
communications, active policy-based network management,
billing systems and in-browser messaging systems.
Results
Through proper data collection, deep analytics and accurate
reporting, implementing monetisation levers and a subscriber
education and communication strategy, the provider
experienced a more than US$ 10 ARPU (Average Revenue
Per User) increase within
six months of deployment.
This positive result was
experienced with negligible
subscriber churn impacts.
This approach enables
operators to align the
growing demand for data
with growing, rather than
stagnant, revenues.
The European waveNot surprisingly, Europe is currently experiencing a similar
OTT explosion that appears to be a mirror image of the
growth experienced in the US market a few years ago. And
despite the Western challenges surrounding the mass market
with film and TV content, a recent industry study indicates
that, in addition to the subscription business model, there
are significant opportunities for European content providers
53Vol. 38 No. 4 - November 2016 Issue
technical
to increase monetisation of video content, in the form of
transactional services, ad-supported offerings and hybrid
bundles. In addition, the research revealed that despite a
number of barriers to entry, industry participants expect
to see steady growth of premium OTT service in all major
European regions. In fact, most markets throughout Europe
are expected to conservatively double or triple their premium
OTT growth by 2017.
As broadband penetration levels rise, IoT devices proliferate
and favourable regulations are introduced, the OTT
environment will continue to expand throughout Europe.
In addition, as leading players, such as Netflix, continue to
emerge, as well as the competition and investment in premium
OTT business models, experts believe that the landscape will
mimic the US OTT experience with innovation and demand
evolving simultaneously. Therefore, it is critical for European
providers to understand the factors that have contributed to
OTT success in the US market and get ahead of the market
with optimisation opportunities.
US lessons learnedIn conclusion, European providers are currently at a great
advantage in that they can get ahead of, rather than simply
keep pace with, the OTT growth explosion by observing the
US evolution and incorporating strategies that have proved
successful.
Understanding subscribers’ high-speed data usage behaviours
at a granular level will allow providers to not only make optimal
business decisions, but also provide their subscribers with the
most innovative broadband experience possible. By leveraging
the network and user behaviour knowledge with cost-effective,
cloud-based tools and solutions, European providers are in a
unique position to not only provide an optimal user experience
but actually monetise the market expansion.

A Design Procedure The design of a physically small, equal phase and equal power 1-to-4 ultra-wideband Wilkinson power divider is presented. Initially, a 1-to-2 divider was designed and optimised for the 3.1GHz-to-10.6GHz range. The 1-to-4 divider was then built using three 1-to-2 dividers and further optimised for full-band insertion loss, return loss and isolation. The circuits were constructed using a 0.75mm thick Rogers RO3035 substrate, and experimentally validated.

technical
IntroductionPower dividers are important for impedance matching in many
microwave and RF systems. In 1960, E.J. Wilkinson added an
isolation resistor to a T-junction power divider, making a quarter-
wave impedance transformer to enhance the return loss and
isolation between outputs [1]. This design has the disadvantage
of narrow operational frequency bandwidth.
Several methods have been adopted to increase the
bandwidth such as the introduction of additional sections
[2] or stabs to a section [3], combining these two previous
methods [4] or using a slotted ground technique [5]. Since
the commercial use of Ultra-Wideband (UWB) technology
started in 2002 [6], a large number of papers have been
published by researchers and industry especially for the
3.1-10.6GHz spectrum band. The UWB power divider must
satisfy bandwidth requirement, constant insertion loss and a
high degree of isolation between ports [7].
UWB power divider designThis article concerns the design and validation of a 1-to-
4 power divider. The first step is to design a 1-to-2 power
divider, afterwards combining three of them to make a two-
stage 1-to-4 divider.
Generally, a single section Wilkinson power divider consists of
two branches of 70.7Ω quarter-wave transformers terminated
with a 100Ω resistive load. However, such power dividers have
narrow bandwidths [8]. To increase this, additional sections of
quarter wave transformers could be added and also terminated
with resistive loads to increase output port isolation [9].
Examples of quarter-wave transformers and their resistive loads
can be found in several tables and charts [9-11].
Initial section impedances and load values for the single-stage
UWB power divider used in this work are shown in Table 1 -
the equations on page 58 allow the width and length of each
section to be calculated [12]:

The circuit was fabricated on a 0.75mm thick RO3035
substrate with permittivity (εr ) of 3.5. This substrate is chosen
in consideration of equation (2), showing that the line width is
directly related to the substrate thickness and inversely related
to the substrate permittivity. The resulting line width must
be thick enough to comply with fabrication tolerance [14].
Additionally, this substrate has a low tangent loss of 0.0015,
thus reducing insertion loss.
Simulation and optimisationThe simulation of the UWB power divider was performed using
CST microwave studio 2015. Initially, the return loss was below
12.5dB, the isolation was less than 14dB and the insertion loss
was between 3.2 and 3.8dB over the band. After optimising
widths, resistor values and ports and section lengths, a better
return loss and isolation were achieved (see the optimised
S-parameter values in Fig. 1 below).

The final layout for the 1-to-2 UWB power divider is shown in
Fig. 2, with overall size of 12.52mm x 19.56mm. The proposed
power divider is one of the smallest size power dividers in
comparison with UWB power dividers from previous work, and
with very good performance as shown in Table 2 [3, 4, 15-17].
After optimisation, the return loss improved by 7.5dB, with a
1.5dB minimum improvement for isolation over the band. The
insertion loss did not change, as it is depends on the substrate
tangent loss and metal surface roughness [18] which were not
changed by the optimisation.
To construct the 1-to-4 power divider, three 1-to-2 power
dividers were used. The final structure has been optimised for
the best S-parameter values: optimised isolation, insertion and
return loss are shown in Fig. 3 below.
The output ports of the first stage, with impedance 50Ω, have
been stretched to connect to the second stage. The impedance
value was unchanged, as it depends upon the microstrip width
and substrate thickness as in Equation 2. There was a slight
effect on reducing the return loss, subsequently corrected by
optimisation.
Fig. 3 below shows that the achieved return loss is below 20dB
over the band for this small 1-to-4 power divider structure
(60.16mm x 19.94mm). The insertion loss is between 6.2 to
7.2dB, and the isolation between output ports is below 16dB
over the UWB band.

fabricated as above on RO3035 substrate dielectric, of 0.75mm
thickness, relative permittivity 3.5 and tangent loss of 0.0015.

sections and 432Ω for the third section. The resistors were

0402 imperial size (1mm x 0.5mm) to ensure a 0.5mm gap
between the two branches of the power divider. The fabricated
power divider is shown in Fig. 4 above.
An Agilent N5242A network analyser was used to measure
S-parameters for the 1-to-4 power divider, shown in Fig. 5. The
return loss is below 13dB over the band, with isolation below
14dB, while the insertion loss is between 6dB and 8dB.
The experimental and simulated results largely agree. Small
differences could be due to several reasons, such as resistor
positioning and soldering. Experiments do show that the return
loss changes when the resistors are shifted, and also that the
amount of solder used with the connector affects the results.
On top of that, fabrication tolerance also has its impact on
results.
ConclusionThis article has presented a small size UWB 1-to-4 power
divider. A multiple section method has been used to achieve
UWB operation (3.1GHz-10.6GHz).
The small size designs for both 1-to-2 and 1-to-4 dividers make
them suitable for applications where size and performance are
critical, such as in antenna array applications. The simulation
and experimental results largely agree, which validates the
design approach.

After 70 years of existence, the Society has accumulated a
tremendous amount of information and data, not only about
the Society itself but also about the industry in general. Of
course, until the ‘90s most of this information was in paper
form with the earliest material somewhat yellowing with age.
Over the last 12 years I have scanned, OCR'd and edited all
our CTE and Broadband Journals and made them available as
downloadable PDF files.
The result is a complete archive of the Society’s Journal from
1946 to date, all available to members as a download from the
website at http://www.thescte.eu/downloads. Over the last
few years, we have also provided an interactive page-turning
version of each issue which is also available online. We intend
to progressively make the complete archive available as page-
turning versions.
On the website, you will also find some fascinating documents
from 1945 showing how the Society was first set up together
with copies of every Annual General Meeting up to the current
day. We also have copies of ‘Crosstalk’ which was aimed at
technicians and produced from 1998 to 2002.
Also available online is an interesting archive of CableVision
News. This was originally published by the Cable Television
Association (CTA) starting in 1973 and provides an interesting
insight into cable at a business level before the introduction of
the new cable franchises in 1983/4.
With such a valuable and fascinating collection of information
from the past, we would encourage all our members to take a
peek into the archives.
To give you a taste of what’s on offer, we have decided to
re-publish a selection of papers from the past. On the next
page, you can read 'Passive Components for Cable Television
Systems - Part 2' by Chris Swires and edited by Ray Seacombe,
published in Vol.11 No.7 of CTE. We have tried to keep the
original format and apologise that the resolution of some of the
figures are not to our usual standard.
This provides an interesting 'compare and contrast' to the
preceding article on the design of a modern Ultra-Wideband
power divider.

3. Spur or Splitter UnitsThe spur or splitter is used to divide the signal into a number of
paths or lines.
The splitter is either an equal split, dividing power equally between two or more lines, or a non-symmetrical split used to tap off a small portion of the power on a through line.
The theoretical minimum loss when dividing signal two ways is 3dB in a matched system. The simplest form of splitter uses a resistive star network to divide power into two output lines. (Fig.13).
Looking into the input, the impedance is that of R2 + RL in parallel with R3 + RL plus the resistance of R1.
where R1 = R2 = R3 this can be simplified to:
It can be seen therefore that any variation in R1, will seriously affect the impedance of both ports of the splitter.
It can also be shown that the power absorbed by the resistors in the splitter is the same as that delivered to the load. This means that the total loss to each port is 6dB as opposed to a theoretical minimum loss of 3dB. This loss means that although the resistive splitter is low in cost and can be made to operate over a very wide bandwidth, half of the power entering the unit is lost.
The availability of modern low loss ferrites has made possible the design of transformer splitter units with very low inherent losses.
By carefully matching the impedances in these ferrite splitters, the signal losses to the output ports can approach the theoretical minimum. The equal splitter gives a loss of about 3.5dB to each of two lines and is almost universally configured, as shown in Fig. 14.
The input transformer is used to transfer the impedance from 75 ohm to 37.5 ohm. This is achieved by a √2:1 turns ratio. The output cables effectively appear in parallel at the centre of T2 (i.e. 2 x 75 ohm in parallel gives an impedance of 37.5 ohm) with the two output signals in phase.
The output transformer T2 is used to provide isolation between the two output ports. A signal applied at output 1 appears in antiphase at output 2 and no current flows in R.
In the event of any imbalance between the two outputs, a current flows in R and the unbalanced power is absorbed.
In an extreme case when one output line is short-circuited, output is still maintained on the other output port. Although some loss is incurred in R, this is only of the order of 1dB on a practical unit.
In Part 1 of this article, published in Vol. 11 No. 4 (February 1979) of Cable Television Engineering, the author dealt with the design considerations and system applications of attenuators and equalisers, with particular emphasis on the importance of good impedance matching.
In Part 2 he deals with the important parameters of the other passives for cable distribution systems. He discusses the design and operation of splitters, subscriber's taps, and system outlets.

The capacitor C, is used to compensate for the inductive reactance of the transformers at high frequencies. Other impedance correction capacitors may be added across the input and output ports.
Non-Symmetrical SplittersThis is the type of splitter with typical side losses of 6 to 15dB
and through losses of the order of 2 to 0.5dB respectively.
The non-symmetrical splitter is normally designed using the principle of directional coupling. The easiest form of coupler to understand simply uses the electromagnetic coupling between two cables as shown in Fig.15.
The signal flowing in the main cable induces a signal into the adjacent cable and the signal flows in the same direction as the main signal. A 75 ohm load is placed at the end of the secondary cable and this acts as a load. The load also absorbs any signal attempting to pass down the coupled cable in the reverse direction; this gives a simple directional tap-off unit. Unfortunately, the amount of coupling is dependent upon the signal frequency and the device cannot be designed for a flat frequency response over a wide bandwidth. Some ‘spur end’ tap-off units have been constructed using this principle and the lowest side loss is designed to be at the highest system frequency. The earlier types employed coils of special cable but later designs used printed circuit lines.
The use of ferrite transformer techniques to form directional couplers enables uniform coupling to be achieved over the full television bands.
A typical hybrid directional coupler is shown in Fig. 16.
The operation of this type of coupler is as follows:
When a signal enters the input it passes into T1, and in the secondary of T1, a signal is induced in antiphase. The signals are represented by the broad arrows (in Fig.16).
The signal entering from the input also induces a signal in the secondary of T1, in antiphase. These two signals add together at the tap to form the output signal.
If a signal attempts to enter from the output of the directional coupler the action is shown in Fig. 17.
Signal entering from the output cable again induces a secondary current in T2 as shown by the dotted arrow. The current induced in T1 is also shown in the diagram.
It will be noted that the current in T1 is in the same direction as before. However, the direction of current in T2 has reversed and cancellation occurs at the output tap.
The amount of power available at the tap is determined by the ratios of T1 and T2. These transformers are made such that voltages across the two secondaries are as near identical as possible to ensure good cancellation of the reverse signal and therefore good directional properties.
The 75 ohm resistor is used to provide back matching for the unit. If a signal enters from the tap the majority of this is absorbed across the 75 ohm load, the remainder being transferred to the input terminal.
The loss from tap to input is the same as that from input to tap. This makes the unit suitable as a signal combiner. A signal entering at either output of the device and flowing out of the input has the same loss as a signal entering the input and passing out via that output.
Both variations on the basic circuit are to be found but all operate on the same principles.
Better symmetry and impedance matching can be obtained from the circuit shown in Fig. 18. Practical considerations, however, make this circuit difficult to construct at UHF.
SummaryThe way in which a directional splitter is defined is as follows:
(a) Through loss - this is the loss on the main line between the input and output or output and input of the splitter.
(b) Side loss - this is the loss between the input terminal and the tap-off or vice versa.
(c) Reverse loss or directivity - this is the loss between the tap or spur output and the output terminal.

In addition to the components shown, most spur units contain extra components. These are the various capacitors used for RLR correction and balancing of the transformer reactances and also line power routing components. The line power components usually take the form of chokes from input to outputs combined with suitable blocking capacitors. These circuits form low pass filters which route the 50Hz line power to the appropriate point. It is not possible to pass high AC currents through the ferrite-cored components used in the RF splitters as saturation of the magnetic material can occur. This will result in amplitude modulation of the RF envelope at twice the supply frequency (hum modulation).
4. The Tap-Off or Tee unitThe tee unit has the same basic purpose as the splitter units.
However, the side losses are normally greater (between 12 and 40dB).
One of the most important requirements in a cable system is to provide adequate isolation between adjacent receivers. This isolation is required to prevent oscillator signals from one receiver passing to other receivers via the relay network.
For this reason, isolation is normally a regulated system parameter. A typical isolation figure for a relay network would be 33dB between any two outlets.
If non-directional tees are used, then the lowest loss tee which could be employed would be 33/2 dB i.e. 16.5dB.
This value may be reduced by the use of directional tee units based on the principle outlined earlier for spur units.
Using the directional technique, the lowest tap value which can be used is that recorded when the reverse loss of the first tee plus the forward loss of the following tee is 33dB (see Fig.19).
The design employed for higher value tee units can be made less complex than that required at low values.
The simplest technique is the use of a simple resistor tapped onto the centre conductor of the through cable (see Fig. 20).
The main disadvantage of this simple tap is that the unit does not present the correct impedance to the television receiver input. If all television receivers were well matched then no reflections would be set up. Most receivers are matched for best noise figures and not best impedance and their input return loss ratio is very poor.
The net result is that standing waves can be set up which may cause a severe ripple in the frequency response of the signal at the receiver input.
The resistive tee may be improved by adding a resistor as in Fig. 21.
The extra resistor provides good back matching and reduces the standing wave problem, but adding the resistor reduces the signal level by 6dB. This in turn means that the series resistor ‘R’ must be reduced to overcome the extra loss and the through loss of the tap is consequently increased. Even so, the resistive tee unit is widely used because of its low cost.
The transformer tap-off is used mainly for frequencies up to VHF.
A typical circuit is shown in Fig. 22.
This tap is an auto-transformer with the side loss determined by the tapping point on the transformer, together with the loss incurred in the series resistor “R”.
This resistor is included to maintain a good back match at the tap which otherwise would be of very low impedance.
This type of tee is suitable for all values from 18-40dB. The shunt resistance of the transformer has so far precluded the use of this type of transformer tap at UHF.
5. The Mechanical Aspects of Equalisers, Spurs and Tee Units
Robust, reliable housings must be provided for tee units. The choice of casing seems to narrow to either a die-cast case or sheet steel can be suitably plated and provided with a plastic weatherproof housing. The design requirements for the housing are made more difficult when it is understood that the unit must accommodate a large variety of cable sizes.
Indeed, the specification for a tee or spur unit which is presented to the design engineer usually takes the following form:
1) Size - must be small enough to fit into the smallest conduit box that the main contractor can get away with...
2) Weatherproofing and rust proofing - must withstand salt spray, acid, wind, rain, hosepipes and dogs.
3) Mounting - must be possible to mount in ten seconds by an engineer perched on a 100-foot ladder in a Force 9 gale.
65Vol. 38 No. 4 - November 2016 Issue
from the archive
4) Cables - must take every cable from a main trunk to a job lot of downlead cable (or even wet string).
5) Terminals - easily secured by an engineer with bananas for fingers.
6) Return loss - infinity.
7) Through loss - zero.
8) Price - about half that of the very best unit on the market!
Needless to say we haven’t yet reached the point where we can meet all these requirements simultaneously.
6. System OutletsTwo basic types of outlets are available for use on VHF/UHF.
These are for loop wiring, where the distribution cable passes through the outlet system and for tee wiring where a single cable comes into the outlet plate from the tee or tap-off unit. The loop wired outlet plate, incorporates the tap-off unit within the outlet plate.
Whilst there is no theoretical disadvantage in the loop wired type of outlet plate it suffers from a serious practical disadvantage. Because the distribution cable must pass into the subscribers home, any disturbance to the outlet can cause the failure of all outputs on that distribution line.
Access to the cable in a subscriber’s home is frequently difficult and if the subscriber is out, faults are difficult to rectify. It is not unknown for a subscriber on a distribution line to “improve” his own signal by removing the tee resistor thus raising his signal level by about 30dB! For this reason, the use of loop wired units is not recommended currently although in some situations the conduit layout leaves no alternative.
The normal outlet used for tee wired systems consists of a socket isolated from the input cable by two or more capacitors (Fig. 23). These capacitors provide safety isolation of the receiver from the cable system and thus other connected receivers. Current regulations for VHF/UHF systems dictate that the isolation components of the outlet plate must withstand a DC flash test of 3KV for one minute without breakdown.
In addition to this flash test, certain clearances must be maintained in the design of the outlet. From a mechanical standpoint, the plate must be robust and is normally made to match the electrical fittings in the dwelling. Where TV and FM outputs are required, a simple diplexing circuit is built into the outlet plate.
On low cost units, the diplexer may simply be an extra resistance in series with the FM output so that the greater power goes to the TV outlet.
Performance requirements for passive network accessories
The choice of good quality network accessories can considerably enhance the performance and reliability of a cable network. Unfortunately, as accessories are required in large quantities there is a temptation for system installers to choose on the basis of cost rather than performance.
If expensive failures are to be avoided, the life of low-cost housings must be studied in relation to the projected life of the network. The electrical performance of the accessories should be carefully examined. A higher-cost passive unit may have lower through loss and where a large number are cascaded, the cumulative reduction in loss can be very significant. It may even allow the use of fewer amplifiers or lower-cost amplifiers, thus more than paying for the higher cost of the passive accessories. As in all calculations of this nature, it is the cost-effectiveness of the components which must be studied. Some network accessories are easier to install than others and there can be considerable cost savings during installation. A five-hundred point system may well have over a thousand network accessories, but only fifteen amplifiers. It is not difficult to see that the right choice of passive accessory is of fundamental importance to the performance of the cable network.

MakingProducts that allow visibility into sophisticated network infrastructures can solve one of the biggest issues for those trying to diagnose and fix complex network issues in a timely fashion.
By Simen K. Frostad, Chairman, Bridge Technologiesthe Complex Simple
You probably saw the news in June: a federal court in the USA
ruled that high speed internet access should be defined as a
utility – affirming the US government’s view that broadband is
as essential to people’s lives as power, water, telephony and
so on.
That ruling will have many implications in terms of regulation –
but just as importantly for us at Bridge Technologies, it confirms
that ours is a vital business to be in. Our business is all about
empowering operators and assuring network reliability and
quality.
We provide the tools that enable network managers and
technicians to understand what’s going on. They fall – broadly
– into two categories. Tools for analysing the network and tools
for making sense of that analysis. Two of those tools recently
won prestigious awards. The first was from the IABM, where
the VB440-V virtual probe won in the “Test, Quality Control &

Solving one of the big issuesWhat was it about the VB440-V that caught the judges’
eyes? “This product allows visibility into sophisticated network
infrastructure, thereby solving one of the biggest issues for
those trying to diagnose and fix complex network issues in a
timely fashion,” they said.
And that, in a nutshell, is precisely what it does. The VB440-V
monitors high density data traffic in core networks, enabling
users to quickly rectify problems affecting quality. It is the first
product of its type to become available that addresses two
issues of significant concern to broadcasters. The first of these
is the transition to higher network speeds: it supports dual
40 Gigabit Ethernet interfaces. The second is that it supports
SDIoIP – a key feature for broadcasters who are making the
sometimes painful transition from SDI to IP. It is also the first
product to feature SMPTE2022.7 dual redundant stream
analysis.
It can be installed almost instantly on any standard high-
performance server blade to allow rapid scaling of capacity. But
the real revolution is the absolute precision with which the VB-
440V can monitor data flows.
It’s all very well being able to monitor a network and gather
huge amounts of data, as the VB440-V does. But for that data
to be useful, it needs to be turned, in real-time, into actionable
information.
At Bridge Technologies, we live by the philosophy that we’re
in the business of making complex things simple – and that’s
where our second award-winning product comes in. ‘Highly
commended’ in the ‘Best monitoring or network management
solution’ category of the CSI Awards at a presentation at IBC
this year, and winner of the Broadcast Beat ‘Innovation in
Content Delivery’ award, also at IBC, the Remote Data Wall
(RDW) allows those responsible for network monitoring and
management to quickly and easily create a visual representation
of network activity, enabling potential problems to be rapidly
identified and appropriate corrective action to be taken.
Our business is all about empowering operators and assuring network reliability and quality.

In common with many of the solutions we’ve developed in
the last few years, RDW acknowledges that, with the rapid
expansion in networks, not everyone who is responsible for
them has yet achieved the high level of experience and expertise
which characterised network operations management when it
was a much smaller industry. In industries such as broadcast, for
example, the transition to IP is a relatively recent phenomenon.
Making sense of dataRDW makes sense of the data. It does this in several ways.

products
Firstly, although RDW can comprise a number of screens in
a video wall-type configuration, it doesn’t need video wall
specialist hardware or skills to install and configure it.
Secondly, because it’s HTML5/browser-based, it can be viewed
from anywhere. The user doesn’t need to be in the data centre -
he/she could be looking from home or a hotel room.
And thirdly, it provides a graphical representation of whatever
data the user wants to see. A graphical representation is, of
course, far more intuitive than plain text, for example, and can
immediately highlight issues or potential problems, enabling
corrective action to be taken faster.
RDW allows the inclusion of data from a wide variety of sources -
from third-party systems, for example, and external information
sources such as weather stations, personnel management
systems and so on. Any relevant information that may impact
how the network is managed can be displayed.
It seems strange to think that, not so many years ago, a
28.8kbit/s dial-up connection was, for many, an unaffordable
luxury. Now, we take speeds of 10Mbit/s and upwards for
granted – just like we take it for granted that water will flow
from the tap, or electricity will come from the socket. At Bridge
Technologies, we believe that these award-winning products
are playing a key role in enabling the same reliability in our
networks that we expect from our water or power supplies.
For that data to be useful, it needs to be turned, in real-time, into actionable information.

Today’s broadband is a life-changing catalyst and compelling business
enabler – increasing prosperity, spurring growth and improving services
from education to healthcare. Our increasing consumption of media-
rich content, often through streaming and downloading video to multiple
devices in the home, effectively drives the demand for higher bandwidth
and super-fast fibre-based broadband access.
Just how widespread is the trend towards streamed content over the
internet? Take a look at Netflix: as of October 2016, the service boasted
86 million subscribers worldwide, including more than 47 million in the
United States.1 This figure is significantly higher than cable and satellite
television network giant HBO’s 32 million U.S. subscribers.2

Telecommunications service providers are responding to the
trend by acquiring streamable content to attract the growing
base of online viewers. We are also seeing increased mergers,
acquisitions and deals with media companies in an effort
to capture market share. BT and AT&T are two marquee
examples of companies shifting from connectivity provider to
digital entertainment provider.
In a record-breaking deal last year, BT bought the rights to
screen a portion of Premier League football games in the
United Kingdom.3 And more recently, one of the biggest
acquisitions of all time was just announced in the United
States with AT&T acquiring Time Warner – including all of its
well-known brands such as HBO, CNN and Warner Bros.4 In
France, SFR purchased NextRadioTV, which includes brands
such as BFMTV and RMC, to gain access to content and to
capture new customers through the established programmes.5
Many other companies across other countries have followed suit
by making moves into the media world.
Recipe for successWith all this competition in a new digital arena, an operator’s
success relies on its ability to attract new customers,
reduce customer churn and increase Average Revenue Per
User (ARPU). In an effort to differentiate themselves, many
operators are offering bundled services that include faster
upload capabilities and better-quality content.
With incumbent service providers delivering Fibre-To-The-
Home (FTTH) services complete with entertainment bundles,
Multiple Service Operators (MSOs) and cable operators need
to continuously provide customers with the most advanced
services and remain competitive. Multi-channel TV, broadband
and telecommunications services are already delivered to
customers over Hybrid Fibre Coax (HFC) networks.
Network upgrades are needed to meet customer demand
for the latest interactive cable television, advanced voice
services and super-fast broadband internet access. MSOs
need to provide new services as efficiently as possible with
the highest reliability and minimum disruption to customers.
Many therefore look to migrate their networks from HFC or
Data Over Cable Service Interface Specification (DOCSIS) to
FTTH and Gigabit passive optical networks.
What’s clear from a government policy perspective is that there’s
a push for service providers to build faster broadband networks
to replace older infrastructure. The latest strategy adopted by
the European Union sets an objective for an internet download
speed of at least 100 Megabits per second for all households by
2025 with a call for funding to build these faster networks.6 To
meet this target, governments across the European Union will
be working over the next decade to increase internet connection
speeds and to address under-served areas with low population
densities that have slow (or non-existent) internet access today.

FTTH for bandwidth demandsTo meet the unprecedented demand for high-performance
services and to ease the competitive pressure in today’s
market, a Fibre-To-The-Home (FTTH) deployment is the
solution for operators who want virtually unlimited bandwidth,
flexibility, scalability, ease of deployment and reliability in their
access network infrastructures.
Every component in an FTTH deployment is critical, but
none more so than the customer connection. The optical
fibre connector is what links a customer to the life-enhancing
benefits of fibre to the home, so access to the entire network
is dependent on the reliability of a single connection point.
Operators used to deploy FTTH with standard SC or LC
pigtails spliced in conventional closures at Network Access
Points (NAPs) and/or distribution points. These closures had
to be opened each time a new customer was connected,
but repeated re-entry into the closure introduced risk of
damage to the active fibre connections, causing failures and
rework. Re-opening closures also increased the potential
for contaminated grommets and silicone sealing, preventing
closures from protecting fibres from water and dust.
This risk of damage and contamination is heightened when
connections are performed by the customer connection team
lacking the same level of installation experience as the network
build staff. When a network is installed poorly, an accumulation
of faults naturally occurs over time. One operator reported that
he had to rework 12 per cent of the network’s active FTTH
connections each year, mostly due to issues caused by re-entry.
Innovative FTTH solution What the industry needed was a more reliable FTTH
connectivity – a new approach designed for the outside plant
to reduce complexity, increase the speed of deployment and
solve the reliability issues of closure re-entry.
A closure’s function is to provide protection against the
elements, including temperature extremes, moisture, humidity
and other harsh conditions. Any mechanism intended to
replace a closure in a FTTH deployment had to perform that
function, meaning the solution had to be rated IP68 for water
ingress and dust protection.
The solution is a hardened connector that itself is rated IP68,

Above: Multiport terminal and splice closure Above: Multiport terminal stubbed
79Vol. 38 No. 4 - November 2016 Issue
products
instead of relying on a closure around the connectivity point to
provide environmental protection. Drop cables in a variety of
lengths are pre-connectorised with the hardened connector,
and they plug into IP68-rated terminals at the distribution point
or NAP to enable easy incremental connection of subscribers.
Even inexperienced installers can complete an installation
without any risk of fibre damage or contamination in a fraction
of the time it used to take experienced technicians to enter
a closure, splice a fibre and re-seal the closure. The result is
increased operational efficiency and significant cost savings
as the customer uptake of FTTH service grows.
Let’s take a closer look at hardened connector technology. The
body features two keys to guide it into the terminal port and
protects the polished connector ferrule end face by protruding
beyond the ferrule. If a connector is banged against a hard
or dirty surface, the end face is protected from damage and
contamination.
These connectors interface with a wide range of terminals
designed for an array of NAP deployment scenarios, including
various sizes, optical splitter capabilities and the option to
cascade multiport terminals so they feed another along a
network route.
The innovation of the hardened connector for FTTH customer
drops has reduced activation times by 40 minutes or more
per subscriber through the elimination of time-consuming
tasks such as: cable set-up, cable access (opening closures),
splicing and easy routing in customer homes through the use
of an indoor/outdoor cable (outdoor cable with indoor 3mm
jacketing).
An innovative pre-connectorised cabling solution is a
cost-effective way to deploy optical fibre in outside plant
distribution networks up to five times faster than traditional
field installations. The pre-connectorised cables and NAPs are
factory tested and available to ship as a complete distribution
cable/terminal system.
The increased speed of network deployment, along with
the reliability of factory testing, offers reduced installation
complexity/need for rework and makes testing easier with
connector access points along the network.
Accelerated FTTH deployments for the futureThe modularity and simplicity of the hardened connector in a
pre-terminated fibre cabling distribution system can accelerate
customer coverage with minimal capital investment. Hardened
connector technology has decreased the need for costly,
high-demand skilled labour, and by installing a 100 per cent
factory-tested plug-and-play solution, has also reduced risk
during installation.
Specifically, it allows capital expenditure (CAPEX) deferment in
relation to service take-up so that operators can adopt a “pay-
as-you-grow” business model for service delivery.
In a competitive environment, in which access to market and
capturing customers is key, reliability and speed are critical.
With these industry developments, operators can respond to
tomorrow’s changing application and bandwidth requirements
more quickly and efficiently – enabling faster service roll-out,
shorter lead times for customer connection and faster time to
revenue.
An operator’s success relies on its ability to attract new customers, reduce customer churn and increase Average Revenue Per User (ARPU).
Every component in an FTTH deployment is critical, but none more so than the customer connection.

Fibre optic broadcast cable is often subject to harsh field
deployment conditions or high-efficiency broadcast installation
requirements. Sporting events are among broadcast's
toughest venues, requiring the rapid pulling of miles of field-
deployable fibre optic cable across fences, through water,
around rough-hewn rodeo arenas and along frozen ski slopes
or blazing racetracks. Remote broadcasts demand the brisk
deployment of dozens of strands of cable to
cameras that fly over football fields, hang from
cranes and are then re-gathered and thrown into
crates to be shipped to the next venue.
Remote broadcasting specialists, such as IMS
Productions, are involved with such rigorous field
environments throughout the year. The cable
that it uses for all the field events that it covers is
deployable broadcast-quality fibre manufactured
by Optical Cable Corporation (OCC). The
broadcast quality of this fibre cable is high enough
to meet the 4K ultra-high-definition broadcasting
standard that IMS Productions is currently field-
testing with Time Warner Cable Sports.
“Our installations range from extremely hot
to extremely cold temperatures,” IMS Productions told
Broadband Journal. “For example, this year we covered the
Alberta Alpine Ski event in Calgary, Canada. At that venue,
we trenched down into the snow with a chain saw to bury
the cable so that groomers could pack snow over the top to
help protect the cable. In total, we laid about 50,000 ft. of fibre
running all the way up the side of the mountain.”

Anritsu Company has introduced the Power Master
MA24507A, a portable, millimetre wave (mmWave) power
analyser that enables simple, numeric, frequency-based
measurement of RF power from 9KHz to 70GHz. Unlike
many other power measurement instruments, no reference
calibration is required. The power analyser can stay connected
to a test system constantly, eliminating the need to disconnect
and reconnect it between test procedures.
“The world’s first frequency selectable RF power analyser,
the Power Master MA24507A, leverages our patented
Shockline technology to address the growing number of
test requirements in mmWave applications, including test of
802.11ad, Wireless HD and E-band products, at every stage
of the product lifecycle,” Anritsu told Broadband Journal.
As signal frequency increases, attenuation due to the air
or cabling grows, which can make power measurements
particularly difficult at mmWave frequencies. The Power
Master MA24507A’s portable size overcomes this challenge
by enabling users to place it directly at the signal source,
including on-wafer measurements.
When system losses are unavoidable, the MA24507A can
make measurements as low as -90dBm at 70GHz, making
it more convenient than large benchtop instruments which
can be unwieldy in the field. USB-powered, the Power Master
MA24507A measures approximately 6×3×1 (inches) and
weighs less than 15oz. – slightly bigger than a smartphone. It
can, for example, be used to make measurements on antenna
towers or with an extension pole to measure small cell signals
from the ground.
“Because the Power Master MA24507A enables frequency-
selective power measurements, users can differentiate
intended signals from unintended signals for the first time. With
spans from 1KHz to full span over the entire frequency range,
it can zero in on a signal of interest in harsh environments,
including those with unintended signals that can impact power
readings. This enables measurements such as channel power
and adjacent channel power to be made, while avoiding spurs
and harmonics,” concluded Anritsu.

system supports resolutions of up to 1080p50/60. It also
performs AES-128 encryption between units.
The DVEO Atlas Media Server Family is designed as a cost-
efficient way for smaller telcos and cable operators to deliver
live and on-demand multi-bitrate IPTV and OTT services. The
multichannel systems ingest H.265 or H.264 live streams over
IP, then "groom" the streams by adding wrappers such as
MPEG-DASH, HLS or RTMP, plus subtitles for closed captions
or multiple languages. Atlas Media Servers are available in
three different configurations.
The Conf Box IP/DOZER is a tiny real-time video conferencing
appliance designed for cost-effective video communications
over poor or congested public or private internet connections.
Thanks to DOZER™ ARQ Automated Packet Recovery, this
encoder/decoder unit will work over unconditioned lines such
as the public internet.
The AD SPOTTER is DVEO's new multi-criteria advertising
platform that uses content and viewer information to make
decisions about the actual ads played out to all viewers,
to dynamically select ads to maximise revenue. The AD
SPOTTER generates SCTE-35 and cue tones with content
type information, interprets SCTE-35 information and the
viewer's receiver data, and then inserts user-targeted ads into
live or stored transport streams. The system can also trigger
"ad starts" via IP messaging, scheduled or manual triggering.
The AD SPOTTER can also insert ads inside, overlaid or
around the video content via slices, overlays, crawl messages,
alert bugs and video squeezes.
The Spark-E II is a portable, compact (5.9 inches) single
channel Linux®-based H.264 encoder, live streamer designed
for encoding 3G-SDI/HD-SDI, analogue or HDMI input from
cameras, or video content from analogue sources. It encodes
this content to one H.264 standard stream, records it and
outputs it to an IP network.
DVEO also demonstrated its latest ad insertion and broadcast
playout server solutions at Broadcast India in Mumbai this October.

Huawei demonstrated the OPEN-O Sun, which it dubbed the
‘world’s first Open Source SDN and NFV Orchestrator’, at the
Operations Transformation Forum 2016 in Wuzhen, China.
The forum brought together industry leaders from around
the world to discuss the transformation of digital operations
and share best practices. Helen Chen, leader of the OPEN-O
Integration Project, noted that the OPEN-O Orchestrator will
soon be commercially available.
OPEN-O enables operators’ end-to-end service orchestration
over Network Functions Virtualization (NFV) infrastructure, along
with Software Defined Networks (SDN) and legacy networks.
"The OPEN-O Sun is the first open source orchestration
platform to facilitate service delivery across NFV, SD and
legacy networks,” said Chen. “It supports both family and
enterprise environments. Involving seven projects, its main
code comes from six companies, including China Mobile and
Huawei."
The OPEN-O Sun adopts the mainstream TOSCA and YANG
models and an open architecture. In addition to OpenStack
and other open source components, it integrates components
in the OPEN-O integration lab from multiple vendors, including
Canonical, Raisecom, Red Hat and Huawei.
The OPEN-O community, supported by carriers, vendors and
the Linux Foundation, plans to continue developing open-
source technologies and ecosystems. OPEN-O, said Huawei,
allows carriers to integrate products from different vendors,
innovate quickly and operate with agility.

Wazee Digital has more than 10 million video assets under
secure management for major studios, governmental
departments, broadcasters, sports federations, news archives
and a range of other content owners and rights holders.
For many of those organisations, asset management is just
the beginning. They also use Wazee Digital for a variety of
related services that help to make those assets searchable,
accessible and, in many cases, monetisable.
“What makes it all possible is Wazee Digital Core, our cloud-
native media asset management system.
Core is at the heart of all Wazee Digital
services. It was built from the ground-up to
operate in the cloud, which brings all sorts of
advantages when it comes to finding, sharing
and monetising content. Core powers
access to transcripts and interviews and
includes advanced metadata-enrichment
capabilities, all of which help people to
quickly find specific moments within a show.
Core also drives the underlying search
experience, which enables online search
portals with granular layers of access.
Once people find what they want, Core can
transcode and package the content as needed for a given
request,” explained the company.
Core embodies Wazee Digital’s years of experience in
monetisation and rights management and allows content
owners to create content once and then use and re-use it
in countless ways, anywhere, in any format. Its media-
management tools underpin various business models for any
organisation that owns video.

It is now possible to perform 4K baseband SDI recording
using standard and affordable PC hardware. Village Island and
DekTec have jointly announced VF-REC v3, a new version of
the VF-REC application widely used for recording of transport
streams and SDI signals using DekTec’s range of video I/O
adapters. With this release, VF-REC receives a major GUI
overhaul and introduces the “J2K” option for JPEG 2000
compression.
"Recording/playout of an uncompressed 4K video stream
in a PC is extremely challenging because of its high bitrate
(12Gbps) and requires a special and expensive hard-disk sub-
system. Without considerable integration effort, it is practically
impossible to record or playout 4K signals with a standard PC
set-up. VF REC v3 overcomes this problem by incorporating
JPEG 2000 compression technology from Comprimato. It
applies real-time visually loss-less compression of 4K video,
reducing the data rate sufficiently to use a PC with a standard
hard-disk set-up. Comprimato’s JPEG 2000 compression
technology leverages the GPU resources from graphics
boards provided by companies such as NVIDIA and AMD,"
said DekTec.
VF-REC stores the JPEG 2000 compressed 4K signal as an
MXF-file (OP1a), which means the recorded files can be used
by any tool supporting the OP1a MXF-file format. Version 3 also
includes functionality for playing back the recorded 4K files.
“While 4K is gaining more and more momentum, broadcast
engineers need concrete and practical solutions to archive
4K while preserving excellent video quality,” said Bernie
Rietkerken, Director of Marketing and Sales, DekTec. “We
are glad that, with this software application from our long-

Kathrein Smart Monitoring is a new kind of monitoring system
for transmitters that creates transparency. The system,
the result of cooperation between Kathrein and the Swiss
company, DAC System SA, uses special sensors to record
important operating parameters in the transmitter components
in real-time and compares them with target values from regular
operation. All deviations are consistently logged to provide
early indication of a potential disturbance.
Transmitter operators can comfortably view the measurements
via network access. If there are any critical changes in status
or if threshold values are exceeded, an alarm is triggered and
signalled via app, SMS message or e-mail.
"This system considerably reduces the time and costs incurred
in monitoring transmitters, because transmitters normally
require regular routine controls," explained Jörg Lippert, head
of sales at Kathrein in the radio antenna division. The Kathrein
Smart Monitoring system can be employed with new antenna
system installations and can also be integrated into existing
systems.
Kathrein has also launched another new development in
broadcasting antennas in the form of the UHF Cavity Slot
series. These models combine uncomplicated connection
and commissioning (Plug & Play) with high broadband
flexibility. The antenna family consists of various types of low-,
medium- and high-power transmitters and displays a low level
of reflectance values.
"Broadcasters benefit from an efficient and cost-effective
broadband antenna solution for the transmission of digital
television channels in the UHF frequency range between
470 and 790MHz,” said Lippert. The first antennas of this
new model series will be delivered to customers in the fourth
quarter of this year.

time partner Village Island and high-performance video
compression technology from Comprimato, we can bring an
affordable solution to this problem.”
The recording and playout of UHD requires the usage of a
4K-capable DekTec adapter. DekTec’s current flagship 4K
product is the DTA-2174 (Quad 3G-SDI/ASI Input/Output
adapter), with multiple new 4K products on the roadmap. As
they appear, support for these cards will be added to VF-REC.

Yokogawa’s compact AQ1300 series 1G/10G Ethernet multi-
field tester unit now features ITU-T Y.1564-compliant test
functionality.
“This rugged handheld device provides
comprehensive test functionality in
the smallest and lightest format of any
10GbE test device on the market, and
the addition of ITU-T Y.1564 functionality
complements the existing RFC2544
compatible network performance tests,”
said the manufacturer.
ITU-T Y.1564 mandates that standard
tests such as throughput, frame loss,
latency and packet jitter are executed
simultaneously, with multiple services
running at the same time. This allows the
measurement of the influence between
services, which can affect the network’s ability to maintain
Service Level Agreement (SLA) conformance, as well as
reducing the time taken to test an Ethernet service.

All well-known multimode and single-mode QSFP applications,
such as SR4, PSM4, PLR4 and FCp, can be converted to
four duplex channels using the new FO-DCS speed converter
plug-in modules from Datwyler. The connectivity of these plug-
in modules splits each of the three incoming parallel optic links
into four duplex links.
40G and 100G applications are now a reality in the data
centre environment, and higher transmission rates will soon
follow. High-speed fibre optic links connect the switches to
each other as well as to today’s 10G servers and future server
generations (25G and 50G). To aggregate such links cost-
effectively at switch level, they have to be split into several
duplex links. This requirement can be met with Datwyler’s new
plug-in modules.
At the rear, the speed converter plug-in modules available
for OM3, OM4 and OS2 have two 12-fibre MTP couplers
and route these 24 fibres using integrated fanouts to 3 x
four duplex ports on the front panel. In combination with a
converter plug-in module at the other end of a 24-fibre link, for
example, three 100G transceivers can be connected simply
and securely to 3 x four 25G transceivers.
The speed converter plug-in modules are designed for use
in FO-DCS panels and sub-racks. Packing densities of up to
288 fibres can be achieved on 3U with this type of module.
They comprise a robust polycarbonate housing (PC) with
press-fit side panels and a 3U/7TE front panel in PC (black) or
aluminium. The PC version has two integrated labelling strips
for customer-specific printing.

Two different kinds of test are available to the AQ1300 series
testers with ITU-T Y.1564 functionality: a configuration test mode
for examining the speed and burst size per contracted service and
performance test mode for measuring guaranteed bandwidth of
multiple services.
In configuration test mode, the AQ1300 performs either
a ‘Ramp Test’, whereby the device outputs a gradually
increasing volume of signals (ramp) and measures the
guaranteed rate and the securing rate, or a ‘Burst size’ test
(in which the device outputs burst of frame signals at regular
intervals and measures the burst bandwidth guaranteed size
and the burst bandwidth securing size). The AQ1300 provides
PASS/FAIL judgement according to specified thresholds of the
Information Rate (IR), Frame Loss (FL), Frame Transfer Delay
(FTD) and Frame Delay Variation (FDV)
In performance test mode, the AQ1300 sends frames within
the Committed Information Rate (CIR) of selected services at
the same time to confirm whether all traffic is sent without
being discarded. The test can evaluate the traffic quality for
the same period for up to eight services.
