Philips Digital Systems Labs, Ronald Tol, 28 January Overview Background TVA Metadata TVA Content referencing TVA example applications Industry adoption

Philips Digital Systems Labs, Ronald Tol, 20 September 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

TV-Anytime functionality Watch what you want, when you want Simpler ways for the consumer to acquire TV content on local storage –click on EPG, trailer, website groups > programmes > segments –series, related material –news items, parts of programmes Personalisation and automatic recording

Philips Digital Systems Labs, Ronald Tol, 20 September 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

Philips Digital Systems Labs, Ronald Tol, 20 September 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

Philips Digital Systems Labs, Ronald Tol, 20 September 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

Philips Digital Systems Labs, Ronald Tol, 20 September 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

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

Philips Digital Systems Labs, Ronald Tol, 20 September All episodes of Foxes ever More Foxes than you can handle crid://hbc.com/comedy/all The one where Fox jumps in the Potomac Fox goes to Washington and jumps in the Potomac crid://hbc.com/foxes/all The one where Fox drowns in the Lake of Geneva Fox goes to Geneva and tries to climb the fountain crid://hbc.com/foxes/all CRID Group information Program information CRID – Grouping example

Philips Digital Systems Labs, Ronald Tol, 20 September CRID – Resolution CRID TOP locator CRID A CRID B CRID C CRID B1 CRID B2 locator A CRID can resolve to other CRIDs At some point, CRIDs must resolve to locations CRIDs resolve to lists (of CRIDs or locators)

Philips Digital Systems Labs, Ronald Tol, 20 September CRID – Hierarchy Example Star Trek Location 1 Original Series Voyager 1995-present Deep Space Nine The Next Generation Season 1: Episode 1: The Man Trap … …… Episode 29: Operation: Annihilate! ……… Season 2: Season 3: … Location 2Location
