MPEG4/IP TELEVISION

• Objectives:– Making TV and Radio flux « routable »

– Making bandwidth compatible with telecommunication networks

– Making the flux « interactive »

– Assuring the change of the transportation support without any loss

– A unique flux - A multiplication of the possibilities

– An internationally developed and accepted codec ISO (1998)

– A utility normilized environment (program guide)

– Exploitation costs at max equal as today ’s

– A quality at least equal as known today (TPS/CANAL/DVD)

MPEG2 - MPEG4

• Television Canal/TPS

• Broadcast mode television• DVB standard (Digital Vidéo Broadcast)

• MPEG2 ISO standard

• Bandwidth 4 to 8 Mbits per channel (D1)

• No interactivity possible

• Difficult to store numerical data

• No « on demand » possibility

• No liaison with the Internet world

• No liaison with the data-processing world

• No liaison with ADSL (bandwidth between 4-6 Mbits)

• IP Television

• Broadcast mode for television/multicast/on demand

• Norm DVB / IP (European Infrastructure)

• Norm MPEG4 ISO

• Bandwidth 512 to 1,5 Mbits (D1 Full Screen)

• IP Interactive (guide of Pg and Java)

• Storage of numerical data

• « On demand » through a server

• IP mode diffusion on the ethernet

• Player on PC/MAC or TV or embedded

• Links to ADSL, TNT and TNT mobile

Technical contraints

• Guarantee a contineous 2 Mbits bandwidth

• Guarantee this bandwidth on all clients sites simultaneous

• Guarantee acces to at least 30 TV channels

• A management of the IP multicast

• Transportation insurance of at least 10 -10 to 10 -11 (ATM ’s necessity)

The chain for delivering the signal

The signal will be routed from any point per satellite (garanteed bandwidth), before arriving on the DSLAM for use of broadcast diffusion in IP/DVB mode.

(guaranteed bandwidth)

Architectural advantages

• DSLAM ’s are automatically duplicating the multicast trames

• The SATBOX manages the subscriptions for the operators

• The IGMP trames pass on to the SATBOX

• The UDP / TCP trames pass on to the ATM commutation

• No modifications are to be made to the ATM architecture

• Bandwidth garanteed by satellite for audio-visual content

• Bandwidth garanteed between the DSLAM and the end user

• « On demand » possible trhough storage on the SATBOX

• Zapping effectuated at the SATBOX level

• The D1 flux bandwidth (720x576) is inferieur than 1,5 Mbits.

• Interactivity assured by a TCP/IP channel in IP mode

Economical advantages

• Easy to install and activate

• Broadcasting a TV channel at less than 150000 Euro a year

• Economical model audiovisual compatible (mass diffusion)

• Justified increase of the ADSL monthly subscription fee

• New services provided by the telecom operators

• Finally an interactive television. MPEG4 can integrate HTML links

• Real effective solution for E commerce (answering mode)

• No important investments per DSLAM (<6000 Euro per 25 TV channels)

• No new infrastructure to be built (Satellite infrastructure)

• Free player for PC and MAC (MPEG4 ISO)
