TVA Metadata

• Assists the consumer in selecting content
• Supports creation and use of user profiles
• TVA metadata includes
• Programme information, Segmentation information
• Related material information
• Purchase information
• User profiles, Usage history
• TVA metadata uses a CRID to refer to content

6
Why standardised metadata?

• Standardised metadata allows
• authoring once for many destinations
• metadata authoring tools that can be supplied to
  many different customers
• editing of metadata that has come from many
  sources
• economy of scale for broadcasters manufacturers

7
Content Referencing

• The CRID (Content Reference Identifier) allows
  for location independent referencing of content
• It is assigned by an authority which also has the
  ability to resolve the CRID to a location
• A CRID points to a single piece of content or a
  series of other CRIDs

8
Why do we need Content Referencing?

• The same metadata can be used for content
  regardless of where and when it is broadcast
• To reference groups of programmes such as an
  entire series
• References can be given before time channel has
  been decided
• References work even if there is a change to the
  scheduled transmission time

A CRID can resolve to other CRIDs

TV Anytime typical flow of data

• Content providers will publish information

  PPV scenarios

Example applications

• Recording from a trailer
• Linkage from Web to broadcast
• Electronic Programme Guide
• Searching for interesting programmes
• Segmentation
