  1. Advanced Interactive Content Demo in Geneva at ISCAS 2K 28-31/05/2000 Gianluca De Petris CSELT

  2. Purpose of the demo • show the prototype of a real application that enhances traditional broadcast DTV with interactive applications • show the satellite based set-up

  3. What you will see • A traditional News program with interactive subtitles and headlines • MPEG-2 Audio/Video • MPEG-2 TS read from file/satellite • MPEG-4 Scene • MPEG-4 is multiplexed in the MPEG-2 TS AMD 7 • MPEG-4 is streamed together with the MPEG-2 A/V • MPEG-4 is synchronized and composed with MPEG-2 video

  4. Screenshot: choice of the language of the speaker and of the optional subtitles

  5. Screenshot: for each news you can know what happened, get a map of where it happened, and who is involved.Meanwhile you can still hear and watch the news in the upper right corner

  6. Screenshot: the map shown by the where button

  7. Still to be integrated • Carousel of the BIFS and the JPEGs that allows the continuos streaming from the satellite • Injection of the MPEG-4 into MPEG-2 TS

  8. Stream production • MPEG-2 Content • News created by NOB (NL) • MPEG-4 • MP4 created by IBM (USA) • conversion and pre-injection editing tools by ENST (F) • BIFS carousel by Optibase (IL) • editing/remux by CSELT (I)

  9. MPEG-2 TS (net or HD) The integrated player (CSELT) IM-1 2D MPEG-4 compositor Render MPEG-4 decs (BIFS, OD, …) MPEG-2 A/V decs DMIF Instance MPEG-4 on MPEG-2 TS DEMUX M2TS

  10. What’s new • MPEG-2 TS tested for backward compatibility with commercial equipment (Optibase Fusion) • Stream compliant with the latest AMD 7 • Now MPEG-2 A/V can be fully controlled by the MPEG-4 scene (move, resize, etc.) • No limitations about composition, no need for a chroma-key rectangle in the scene • The terminal can now receive MPEG-4 + 2 over MPEG-2 TS from the satellite

  11. Who made this demo - 1 • MPEG-2 A/V Production • P. Mulder (NOB - NL) • MPEG-4 Scene creation • J. Boston - M. Kim (IBM - US) • MPEG-4 Scene conversion to text • J.C. Dufourd (ENST - F) • MPEG-4 BIFS carousel • Zvi Lipshifz (Optibase - IL)

  12. Who made this demo - 2 • MPEG-2 and MPEG-4 integrated player • M. Balestri (MPEG-2 demux, satellite integration) • A. Campassi (logistics) • G. Franceschini - M. Rossi - P. Panicciari (MPEG-2 TS DMIF instance, MPEG-4 Publisher) • G. De Petris - L. Lupo (satellite integration, testing) • A. Varesio (MPEG-2 Video and MPEG-1 Audio decoders optimization) • IM-1 in MPEG -thanks in particular to G. Di Cagno • Thanks to the IST NexTV Project which funded part of this work
