  2. 목차 • 맞춤형 방송 서비스? • 맞춤형 방송관련 표준 동향 • 맞춤형 방송 서비스 예 • 국내외 관련 기술 동향

  3. What’s Metadata ?

  4. 맞춤형 방송 서비스 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 “Watch what you want, when you want”

  5. Metadata? Content is King, Metadata is Queen!!! Data about Contents Contents Description Information MPEG-7, TV Anytime Forum, CableLabs

  6. Metadata Content Description Metadata Description Audio/Video Information Program Information Group Information Media Review DS Instance Description Metadata Program Location Service Information Segmentation Metadata Segment Information Segment Group Information Consumer Metadata User Preference Usage History

  7. Metadata Process

  8. Selection Mechanism using Metadata metadata search Choose product from catalogue select Pay, and get a piece of paper Location resolution Take piece of paper to someone else acquire Get product (from the TV Anytime Forum material)

  9. 맞춤형 방송 관련 표준 현황

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

  11. 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

  12. 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

  13. 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

  14. CRID – definition Format of authority: CRID:// <authority> / <data> DNS name

  15. 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

  16. 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

  17. 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

  18. DVB 2.0 Tool Box MHP (Interactivity) Mobility, Storage, Networking Content Protection Metadata Audio/Video Service Descriptors Storage DVB-TS and/or DVB-IP Protocols DVB S/C/T etc + Anything supporting IP
