TVAF - Business Models

• Model 1a and 1b - Basic ‘push’ model. “does not require communication from the end user to the service provider”

• Model 2 – User Response model“limited return channel provides the capability to inform the service provider of user selections, profiles and other requests”

• Model 3 - Full interactive model“continuous return channel, integration between multiple content providers, services providers, resource locators and the Internet”

TVAF - Content referencing

• To disconnect a piece of content from its location in time and space.

• Specification out for comments in July, now published at September meeting:– Content Reference ID (CRID)

CRID://<authority>;<data> – (transport dependent) Locator– Location resolution

Resolve CRIDs in Locators or other CRIDS

TVAF - Metadata

“Data about data”

• A common framework

• Limited bandwidth

• Exchangeable and interoperable

• Co-operation with SMPTE, EBU, MPEG-7

• Preliminary specification completed at September meeting

TVAF - Rights management

• To rightfully utilize material on a local storage device from both broadcast and on-line sources

• At least 2 months delay

• Preliminary requirements document completed at September meeting

What is myTV?

• 2-years project funded by the European Commission under the IST programme

• Started 1 January 2000

• Aims to provide an interoperable TV-Anytime solution for DVB

• Partners– CE equipment manufacturers: Philips, Nokia– broadcasters: BBC, RAI, NOB– service providers: UoL, NDS

Objectives

• Implement a consumer platform with built-in local storage

• Develop TV-Anytime services exploiting this platform

• Provide true interoperability, both across different service providers and across different box manufacturers

Some assumptions

Co-operation with service providers / broadcasters

enables a low-cost implementation of TV-Anytime.

Experimenting with applications utilizing local

storage helps in defining local storage extensions

to MHP.

Future plans

TVA phase 1– To search, select, acquire and rightfully utilize

material on a local storage device from both broadcast and on-line sources

TVA phase 2– To transfer material between local storage devices

using home networks and exchangeable media and to micro-navigate around the rich content.
