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>

A CRID can resolve to other CRIDs

At some point, CRIDs must resolve to locations

CRIDs resolve to lists (of CRIDs or locators)
