TVAF - Working Groups
• 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 - System Design
• 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)

– (transport dependent) Locator
– Location resolution
Resolve CRIDs in Locators or other CRIDS

TVAF - Content referencing
“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 - Metadata
• 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
TVAF - Rights management
• 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
What is myTV?
• 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
Objectives
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.

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.
