  1. 3-D virtual worlds for broadcast televisionIST project MADISON Thierry Keutgen Senior Application Engineer DELTATEC t.keutgen@deltatec.be www.deltatec.be

  2. Television ? Internet ?

  3. 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

  4. How do we make it happen ? • Deltatec is a • High-tech explorer for its customers • Specialist in broadcast This revolution is an opportunity • It’s far from trivial … R&D work needed

  5. European IST Project With real-world objectives it is a nice framework to • Meet technical experts • Meet industrial end-users • Explore new technical fields • Get a technical edge for our customers

  6. Idea – Issues - Solutions

  7. 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 • BROADCAST

  17. 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

  18. 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)

  22. Prototype STB - MadBox • Based on a PC running Windows 2000 • QAM receiver board and demultiplexer • MPEG-4 DMIF for • Local files • Internet • Broadcast • Customised housing • Everything managed through a TV remote control

  23. Broadcast DMIF

  24. Top-level terminal layers Broadcast DMIF Instance BroadcastInstance Class DAI Primitives Callback Methods FlexMux DMIF Filter Local Files DMIF Network DMIF Broadcast DMIF Application Layers (Decoders + Compositor) Sync Layer MPEG-4 Parsing functions Delivery Layer MPEG-2 Parsing functions Low-level TS access functions Broadcast DMIF Delivery Medium (MPEG-2 Transport Stream)

  25. 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

  26. 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, …

  27. Get concrete

  28. DELTA-asi DELTA-sdi From a MADISON prototype … to a range of products www.deltacast.tv

  29. Get concrete • 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, …
