3. Philips Digital Systems Labs, Ronald Tol, 20 September 20043 Philips Research activities related to TVA 1995 SMASH –basic HD recording 1998 STORit –getting the right programmes –TV Anytime concept, standardization in DAVIC 2000 myTV –interoperable TVA solution for DVB –standardization: TVAF, DVB, IETF, W3C, MPEG 2001 Share it! –personal content sharing in home-to-home networks

5. Philips Digital Systems Labs, Ronald Tol, 20 September 20045 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. Philips Digital Systems Labs, Ronald Tol, 20 September 20046 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. Philips Digital Systems Labs, Ronald Tol, 20 September 20047 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. Philips Digital Systems Labs, Ronald Tol, 20 September 20048 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

9. Philips Digital Systems Labs, Ronald Tol, 20 September 20049 CRID – definition Format of authority: CRID:// / DNS name

12. Philips Digital Systems Labs, Ronald Tol, 20 September 200412 CRID – Hierarchy Example Star Trek Location 1 Original Series 1966-1969 Voyager 1995-present Deep Space Nine 1993-1999 The Next Generation 1987-1994 Season 1: 1966-1967 Episode 1: The Man Trap … …… Episode 29: Operation: Annihilate! ……… Season 2: 1967-1968Season 3: 1968-1969 … Location 2Location
