Television ?
Internet on TV …… TV on Internet
Is it the issue ?
Television is evolving in a new framework
New business models: pay TV, pay-per-view, games,
T-commerce, …
Content to multiple types of supports

MPEG-4
MPEG-4 allows to wrap 3-D synthesis
information into more general mulitmedia
structures where video, audio, 3-D and image
objects coexist and interact
NOT low bit rate video
NOT encoding / decoding
NOT internet

MPEG-4 over MPEG-2 injector
Different options to inject data over a MPEG-2 TS :
Raw data over a MPEG-2 TS
IP over MPEG-2 TS
MP4 file hinting and
injection
«True» MPEG-4 SL-Packets
embedding through a
DMIF interface
Brussels, 28th November 2003
MPEG-4 over MPEG-2 injector
Based on a PCI board with:
2 DVB ASI transmitters and 2 receivers
Reconfigurable I/O controller to process MPEG-2 TS
Applications:
PID filtering and TS processing
DVB MPEG-2 video servers
Interactive Television (iTV)
IP data insertion/Data broadcasting
Video over IP (VoIP)
Video-on-Demand (VoD)

MPEG-4 for broadcast…
for now
MPEG-4 is not just low bit-rate video
Authoring tools are missing
3-D is really a step forward
MPEG-4 and 3-D are very demanding for the STB
Enhancements are good, content is key
Brussels, 28th November 2003
Next R&D step
We are ready for MPEG-4 in broadcast
We want to go further
IST ENAMORADO project:
Production of multimedia content for live events: AR,
metadata, transmission, …
Delivery to multiple types of mobile clients
Focus on MPEG-7, R&D on MPEG-21
Deltatec, Canal+, Siemens Mobile, …

STB processing power is market-driven …
Manufacturers still to endorse the technology
Let’s demonstrate the technology on programs that pay
In football: ad insertion, synthetic replay, new camera
views, T-commerce, virtual after-match pub, …
