Introduction to DVB-GBS 0005r15

• By definition, TV-Anytime is independent from
• The transport layer
• broadcast networks, broadband, mobile networks,
• The type of terminals
• PVR, PC, PDA, Mobile phones
• The group DVB-GBS
• has specified how
• TV-Anytime data must be signaled and carried in
  DVB transport streams
• has extended and adapted TV-Anytime
• to fit the unidirectional environment
  requirements
• to better target low-cost receivers

Demonstration Synopsis

• End-to-end TV-Anytime System
• Based on DVB-GBS 0005r15 specification for
  unidirectional delivery of TV-Anytime metadata
• BBC server equipement (Linux server and DVB-T
  modulator)
• Pioneer DVB-T terminal (24MB de SDRAM, 4MB Flash,
  STM 166 Mhz processor )
• EXPWAY BiM software (Encoder Decoder)
• Delivery of TV-Anytime EPG via DVB
• Metadata service (19 TV radio channels for 7
  days) delivered using the DVB Object Carousel
• Location resolution supported by a separate
  Content Referencing Information (CRI) service
  carried in MPEG private sections

5
System Architecture

• TV-Anytime metadata files are imported and
  encoded in order to generate 2 data streams
  (metadata and CRI)
• A DVB multiplex is assembled by combining the 2
  data streams together with video streams
• The complete multiplex is then presented to the
  modulator through a DVB ASI interface

TV-Anytime metadata utilized

• Program Information Table
• CRID
• Title (average size 15 characters)
• Synopsis (average size 112 characters)
• Genre, Keywords, Related Materials (web-site
  URL), content formats (16/9, stereo,)
•  Program Location Table
• CRID
• Program Location
• Date/start time
• Duration

TV-Anytime vs EIT a bandwidth advantage

• Metadata are 4 times smaller to carry than their
  EIT equivalent
• Statistics on the EPG service presented
  (equivalent to EIT)
• Object Carousel Sections - TV-Anytime metadata
  61,2Ko
• DVB EIT Schedule Sections 250,7Ko
• A format that is therefore suitable from low-end
  receivers to high-end PVRs

8
TVA vs EIT a Convergence enabler

• A format that allows the Convergence with mobile
  terminals
• Author data once only and enlarge your audience
  by distributing to many devices

Ex. of TVA EPG based on BBC TVA MD Symbian 6.0,
Nokia 3650 platform
9
Conclusion

• A standard suitable to low-end receivers as well
  as high-end PVRs
• A format reducing bandwidth costs for metadata
  carriage
• A format that allows convergence with mobile
  terminals services
• A concrete testing framework in Europe with the
  UK DTG TV-Anytime Testbed Project
