Metadata for non-tape-based camcorders for broadcast production

EBU Committee First Issued Revised Re-issued

PMC Nov. 2005

Keywords: Metadata, acquisition tapeless

1. IntroductionThe purpose of this document is to provide manufacturers and system designers with a definitiveview of the Metadata requirements for non-tape-based camcorders being used in a productionenvironment.

General Metadata requirements for non-tape-based camcorders are summarised in section 2.Section 5 provides guidelines on the use of Metadata attributes, whilst technical and programme-related Metadata items are listed in Annex A.

The Metadata requirements given in this document represent the expectations of users for a newgeneration of camcorder. The EBU is aware that the products available at the time this documentwas published may not satisfy all of these Metadata requirements. Broadcasters are neverthelessinvited to use the list of requirements for the evaluation of camcorders whilst bearing in mind theguidelines provided in Section 5. The EBU intends to collaborate with manufacturers over theadoption and implementation in new products of the Metadata presented in this document.

Further work will be conducted within the EBU on the definition of common processes and aconceptual common data model to support integration across future systems for production andbroadcast, which will lead to a revision of the present document in due time.

2. Basic requirements and provisionsThe following basic requirements and constraints apply to the Metadata items listed in Annex A:

2.1 Requirements• The Metadata items in Annex A are relevant for all non tape-based camcorders including

those for ENG (Electronic News Gathering);

• A camcorder shall process Metadata on a per-shot basis, where a shot can be one frame orany number of contiguous frames. However, it has to be taken into account that shotsrecorded on one storage medium may belong to different productions. Therefore, amechanism is provided to associate a shot with a particular production.

• All Metadata shall be accessible at shot granularity and shall be editable. It shall alsosupport enrichment by subsequent devices and systems.

• A mechanism must be available to prevent accidental over-writing of Metadata.

• Camcorders shall automatically generate (create) “Technical Metadata” for each shot.

• In addition, camcorders shall support addition (read and record) of “production relatedMetadata” that are provided via an interface such as a RAM (Random Access Memory) or an

optical network interface. This must be possible at the time of acquisition or later. It mustbe taken into account that all “Production Related Metadata” acquired over such aninterface must remain in its original form on the recording media, if so desired.

• Required Metadata must be arranged into logical groups. The arrangement detailed inAnnex B (B.4.1) meets foreseeable requirements;

• Handling of “Good Shot Flag” should be supported;

• Handling of “Instant Marker” should be supported. There may be multiple Instant Markers inthe same shot, For example during a sports event;

• Thumbnails / Images and Browsing / LowRes (low resolution) should be handled asMetadata.

2.2 Constraints• It is expected that the file format used for the import and export of Content shall be MXF.

Therefore, the Metadata and its structure should support integration into MXF and itsfunctionality.

• Fast and direct access to Metadata, separately from the Essence, must be supported throughthe provision of an independent interface, e.g. XML, in order to support typical productionenvironments where editorial staff may use Metadata only for certain tasks.

3. General usage of the Metadata list

3.1 Production Elements (PE)A PE object puts together all “Production Related Metadata” for a particular recording / shot.

A PE object must be generated by the camcorder for each recording/shot. “Production RelatedMetadata” provided via an interface will usually supplement it.

In such cases where no “Production Related Metadata” is provided, the camcorder must at leastcreate a PE object populated by a character-based sequence number generated automatically forevery new shot.

3.2 Physical Realisation and Storage (PRS)Basically, each recording / shot generated by the camcorder consists of Essence which is stored onthe media and described by “Technical Metadata”, which are put together under the correspondingPRS (Physical Realisation) object, as shown in Annex B.

Each PRS object always relates to a single PE (Production Element) object, as shown in Annex B.

In order to distinguish between shots of different productions, shots belonging to the sameproduction can be marked, e.g. using information elements of the “Production” group.

In order to handle the “good shot flag” as part of the PE Metadata, a group of information elementscalled “Cue / Keypoint” is being used. This group also supports the handling of “Instant Markers”.In this case several instances of the group can be generated in order to create a list of instantmarkers within a single shot.

The PRS group supports both the handling of “Key-frames / Thumbnails / Images” and “Browsing /LowRes” as part of the Metadata. If necessary the PRS group can be generated several times inorder to handle several physical representations (Essence) of the same shot. For example, aphysical representation can be a HighRes version, or a LowRes version, or Images.

Annex B provides additional information concerning the intended use of the Metadata specified inthis document for non-tape-based camcorders.

4. UMID – Unique Material IdentifierA camcorder shall automatically generate and record extended UMIDs.

When the extension is configurable such as the commutation of GPS data, it should reconfigure thedata in the extended UMID Source Pack for each recording process.

The relevant references are:

• SMPTE Standard 330M-2004 for Television — Unique Material Identifier (UMID)

• SMPTE RP 205-2000 — Recommended Practice on Application of Unique Material Identifiersin Production and Broadcast Environments

• EBU Technical Statement D92-2001 - System Requirements for the unique identification ofmaterial in broadcast production

• EBU Technical Recommendation R108-2001 - High-level rules for systems implementing theSMPTE UMID.

5. Metadata for non-tape-based camcordersThe EBU has defined a list of Metadata attributes to be used at acquisition on non-tape basedcamcorders. This list can be found in Annex A of the present document.

Based on this list, the EBU recommends that:

1. Production information, captured by and provided to the camcorder during acquisition, shallcomply with the present document, and more particularly,

2. Metadata is processed on a shot basis;

3. The following production related information (Descriptive Metadata) is supported:

a. All "Title" related information;

b. All "Identification" related information;

c. The mandatory fields of the "Production" related information;

d. All "Location" related information, noting that it is expected that GPS capable equipmentshall additionally provide GPS co-ordinates;

e. All "Cue / Keypoint" related information.

4. The Technical (structural) Metadata information is fully supported, noting that UMIDs(Unique Material Identifiers) are components of the technical Metadata and shall followSMPTE 330M, SMPTE RP205, EBU D92, and EBU R108.

Although not mandatory, other production related information (Descriptive Metadata informationsuch as "Participant", "Person", "Organisation" and "Address") is highly desirable.

Annex A: Metadata list for non-tape-based camcorders

A.1 IntroductionThe list represents a compilation of attributes required for camcorders in acquisition mode.

The definitions and writing style of the name, description, value attributes and value type areconsistent with those already defined in relevant Metadata standards, such as the SMPTE MetadataDictionary (SMPTE RP210) and P_META (EBU Tech 3295).

Some examples of relationships (focusing on the meaning of the attributes but not considering theirdata types) with the Attribute lists in EBU Tech 3295 and SMPTE RP210 are given in the followingtable in the columns labelled “T3295 Rel.” and “RP210 Rel.”, respectively.

The following table also gives a definition for each indicator used within the Metadata list.

Annex B: Usage of Metadata for non tape-based camcorders

B.1 IntroductionThe purpose of this annex is to provide an overview and explain the intended use of the acquisitionMetadata listed in Annex A of this document.

This Metadata collection addresses requirements identified using the results of a questionnairedistributed among EBU members. In addition to fundamental Metadata this document defines anumber of information attributes that shall be generated and processed by non tape-basedcamcorders.

The Metadata list has been subdivided into two sections: “Technical (structural) Metadata” and“Production Related (descriptive) Metadata”. Technical Metadata shall be automatically generatedby the camcorder and related production Metadata shall be provided to the camcorder through anexternal interface such as RAM or wireless LAN.

B.2 Scope of useThe list of Metadata given in this document has been developed in order to reflect therequirements of the EBU members for non tape-based camcorders in acquisition and it is not a listof Metadata that is sufficient for further production steps or the whole production process.

Knowing that the recording process of a camcorder in acquisition is just a small part of the entireproduction process, the attributes have been structured to be compatible with common practice inan operational production environment. All these attributes and groups have relationships and havealso a context in the real production environment.

Subsequent production steps, e.g. editing, will require additional attributes in order to support thedescription of these further processing. These attributes must have a structure corresponding tothose already generated by the camcorder in acquisition. It is acknowledged that comprehensivespecifications concerning Metadata for the whole production process may only be possible on thebasis of a widely agreed information model.

B.3 UtilisationThe following figures describe the contextual meaning of the groups and attributes, step by step.Explanatory comments have been added in order to provide an introduction concerning theintended usage and a basis towards implementation.

For integration into a comprehensive production environment several steps will be necessary.Although not absolutely necessary, the first step would preferably require a more detaileddescription, definition and final agreement on a basic information model.

B.4 General OverviewFigure 1 below provides an overview of the relationship between individual Metadata groups. Thenumber in each box refers to the corresponding group within the Metadata list.

A basic requirement is that subsequent systems must be able to distinguish between Metadata foracquisition and Metadata relevant for further production steps. Consequently, the group “PE(Production Element)” of the type “Shot” has been introduced, which gathers all Metadata of ashot at acquisition. For further production steps other PEs of, for example, type “Item” or“Programme” will be more relevant.

Production Related (descriptive) Metadata (above the dotted line) supports both the process stepof acquisition itself and the description of the Content of the shot.

Technical (structural) Metadata (below the dotted line) supports the Essence description of theshot. These groups can be used to describe the recorded Essence by means of individual tracks andrelated storage information. Each of the Essence related Metadata is represented by a “PRS(Physical Realisation and Storage” group including e.g. HighRes, LowRes (Browsing), and Image(Thumbnails).

Figure 1: Relationships of Metadata Groups

B.4.1 Production Related (descriptive) MetadataAll required programme related (descriptive) information have been organised into meaningfulgroups. Figure 2 below shows the relationship between a “PE (Production Element)” of the type“Shot” and descriptive Metadata groups:

• The Title group supports the designation of a shot either by a continuous number for shotsbelonging to the same sequence or/and textual information;

• The Identification group supports the usage and handling of identifiers. It also provides thepossibility to distinguish between different productions by marking shots belonging to thesame production;

• The Production group supports the description of organisational matters;

• The Cue / Keypoint group supports the handling of “good shot flags” and “instant markers”;

• The Location group supports the description of the kind, the name and the geographical co-ordinates of a location;

• The Participant group supports the description of the role type, responsibility, or taskundertaken by an organisation or an individual, e.g. a cameraman;

• The Person, Organisation and Address groups can be used to describe in more details thelocations or participants involved, where the following considerations have been taken intoaccount:

o A participant can be a person or an organisation;

o A person can be part of an organisation;

o A location, person and organisation can be further described using the Addressgroup;

Note: If required every individual group above can be generated several times in order to describevarious states that may be necessary for editorial reason, e.g. various participants, where each ofthem is designed by its function (job).

Figure 2: Production Related (descriptive) Metadata

B.4.2 Technical (structural) MetadataIt must be assured that different representations of the Essence, which may also be stored ondifferent carriers, can be described independently from each other.

The PRS (Physical Realisation and Storage) group is the bracket that gathers all informationconcerning the physical realisation and storage. Intentionally, several PRS groups can be used forthe description of different representations of the same Essence of a shot, e.g. HighRes or LowRes,independently from each other.

PRS10 PRS10

Figure 3: Basic step for the Essence description of the shot

The PRS group itself defines the time code borders of a shot to which a particular set of structuraland descriptive Metadata relates.

B.4.3 Basis structure for the Essence descriptionIn TV production, the physical realisation of the Essence is usually organised in tracks. Describingthe Essence by means of individual tracks is advantageous. Therefore, the Instance group can beused to describe tracks:

• An instance can represent any number of tracks;

• Because of individual properties of audio and video tracks the descriptions are separated foreach of them;

• The Video Instance group supports the description of the video track properties includingthe identification of the Essence.

• The Audio Instance group supports the description of the audio track properties includingthe identification of the Essence.

• The Instance Wrapper group supports the description of the kind and location of the storedEssence;

• If necessary the PRS group can be generated several times in order to handle severalphysical Essence representations of the same shot.

• A physical representation can be the HighRes version, the LowRes (Browsing) version orImages (Thumbnails) for example.

B.4.8 LowRes (Browsing) as part of the MetadataA separate PRS group can be used to handle a LowRes representation of the Essence (Browsing) aspart of the Metadata:

• For the description of the LowRes Essence the available groups can be used in the same kindand manner as for the HighRes Essence (see above);

• Usually, the description of the LowRes Essence can be carried out with much lessexpenditure (using just a few attributes) than the description of the HighRes Essence;

• Usually, the description of the image Essence can be carried out with much less expenditurethan the description of the HighRes Essence.

• Therefore, a separate Image Instance group supports the description of the images /thumbnail / key-frame Essence.

B.4.10 Several images (thumbnails) within one shotIn correspondence with the user requirement for instant markers (accompanied by a thumbnail),which may occur a multiple number of times during one shot, groups can be used as follows:

Figure 11: Several images (Thumbnails) within one shot

• The Image Instance group can be generated several times in order to handle severalthumbnails / images within the same shot.

• The Instance Wrapper group can be generated several times in order to support thedescription of thumbnails / images that are stored on different media.

• However, only one Instance Wrapper group (as indicated by dotted lines in Figure 11) isnecessary if all thumbnails are stored on the same media.

B.4.11 Description of the image EssenceThe Image Compression and Image System groups provide the limited but specific information thatis required for the description of an image instance, as illustrated in Figure 12.

Figure 12: The relationship of the Image Instance group with other groups

B.4.12 Overview exampleFigure 13 provides an overview example for the usage of the available groups if a certain shot isrepresented by three different physical representations: HighRes version, LowRes Version and aKey-frame version:

• It is to be emphasized, that each shot can be described by one set of production relatedMetadata only (see Figure 13, above the dotted line).

• However, several physical representations of the Essence can be handled simultaneously bycreating several PRS groups.

• For the description of a LowRes representation the same groups and attributes are usedthan for a HighRes representation but with much less expenditure and held together by aseparate PRS group.

• The information about the image representation is held together by a further PRS groupthat relates to this physical representation only.

B.4.13 Usage of the groups Media and DeviceBasic considerations for the intended usage of the Media and Device groups are:

• Each instance wrapper may be stored on an appropriate media.

• Instance wrappers belonging to the same shot may be stored on the same media.

• Instance wrappers belonging to the same shot may also be stored on different media.

• The properties of the storage media can be described using the Media group.

• The properties of the device used for the physical realisation of an instance can bedescribed using the Device group.

Figure 14 shows an example of HighRes, LowRes and Image stored on the same carrier using thesame device.

Figure 15 shows an example of HighRes and LowRes stored on one carrier while the Image is storedon another carrier.

B.5 Further steps towards implementationThis annex explains the intended usage of Metadata for non tape-based camcorders, which aregenerated on a shot-per-shot basis. However, within the framework of an entire productionprocess, a single shot almost always relates to the creation of an item or a programme, which itselfalso may have been planned in advance of the realisation of the shot. Therefore, an integratedview of Metadata for programme production must consider such relationships. Figure 16 shows auniversal representation of these relationships by means of a basic information model.

Figure 16: Core structure of the basic information model

This model shows the fundamental Content structure. A programme may consist of items, scenesand shots. An item may itself consist of scenes and shots. The suggested sequence represents adetailed Content-related description addressing different segmentation aspects of the programme,item, scene or shot.

This structure must be able to describe the utilisation of parts or full pieces of Content from alower level at a higher level within the hierarchy, e.g. the utilisation of shots within an item.Essence is not systematically required for such a description. This method also supports an editorialconcept where the construction of programs, items or scenes can already be planned in advance.

Another peculiarity of such a basic information model is that every level of the hierarchy can haveone or more representative versions of the Essence, e.g. an item may be available as both aHighRes version and a LowRes version.
