Introducing TV Anytime Phase 1 Ronald Tol Technology Manager, Philips Digital System Laboratories Convenor TVAF STC Working Group
Overview • Background • TVA Metadata • TVA Content referencing • TVA example applications • Industry adoption
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 acquireTV content on local storage • click on EPG, trailer, website • groups > programmes > segments • series, related material • news items, parts of programmes • Personalisation and automatic recording
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
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
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
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
CRID – definition Format of authority: CRID:// <authority> / <data> DNS name
CRID – Grouping example Group information Program information <GroupInformation GroupId="crid://hbc.com/foxes/all" GroupType="show" Ordered="true" NumberOfItems="2"> <BasicDescription> <Title type="main">All episodes of Foxes ever</Title> <Synopsis Length="short">More Foxes than you can handle</Synopsis> </BasicDescription> <MemberOf>crid://hbc.com/comedy/all</MemberOf> </GroupInformation> <ProgramInformation ProgramId="crid://hbc.com/foxes/episode1"> <BasicDescription> <Title type="main"> The one where Fox jumps in the Potomac </Title> <Synopsis Length="short"> Fox goes to Washington and jumps in the Potomac </Synopsis> </BasicDescription> <MemberOf>crid://hbc.com/foxes/all</MemberOf> </ProgramInformation> <ProgramInformation ProgramId="crid://hbc.com/foxes/episode2"> <BasicDescription> <Title type="main"> The one where Fox drowns in the Lake of Geneva </Title> <Synopsis Length="short"> Fox goes to Geneva and tries to climb the fountain </Synopsis> </BasicDescription> <MemberOf>crid://hbc.com/foxes/all</MemberOf> </ProgramInformation> CRID CRID CRID
CRID – Resolution CRIDTOP CRIDs resolve to lists (of CRIDs or locators) A CRID can resolve to other CRIDs CRIDA CRIDB CRIDC CRIDB1 CRIDB2 locator locator locator locator locator At some point, CRIDs must resolve to locations
CRID – Hierarchy Example Star Trek Original Series 1966-1969 The Next Generation 1987-1994 Deep Space Nine 1993-1999 Voyager 1995-present … … … Season 1: 1966-1967 Season 2: 1967-1968 Season 3: 1968-1969 … … … … Episode 1: “The Man Trap” Episode 29: “Operation: Annihilate!” Location 1 Location 2 Location
TV Anytime typical flow of data • Content providers will publish information (metadata) about their content, which can be used in a search and select process • Selected content can be located and acquired for viewing • A finishing phase is foreseen e.g. to deal with PPV scenarios
Example applications • Recording from a trailer • Linkage from Web to broadcast • Electronic Programme Guide • Searching for interesting programmes • Segmentation
Electronic Programme Guide Using TV Anytime data, you can create an EPG with data from many sources.
Searching for interesting programs Using TV Anytime data, a consumer can search for interesting content without knowing where or when it will be broadcast
Searching for interesting programmes using a bi-directional link Two step process: • Find out from the server what can be queried • Make a query using supported fields. “What search fields do you support?” service description actor=“John Wayne” and genre=“film” Programme metadata that matches query
Industry Adoption • Transport mechanisms for TVAF data have been incorporated into DVB-GBS specifications and are being verified in UK DTG testbed (Europe) • ARIB have adopted TVAF (Japan) • ATSC have selected TVAF metadata (US) • IPTC have produced a ProgramGuideML, and have adopted TVAF metadata • EBU P/Meta is TVA compatible, using many common elements (Europe) • Companies in US, Europe, and Asia are developing TVA-compatible products
