  1. Presents Fall Forum 2002

  2. 3G and MultiMedia over IP Presented by David Singer on behalf of ISMA Apple Computer, QuickTime Group

  3. What’s Technically Exciting? Quality CPU Performance Bandwidth Compression efficiency Calendar time 3G & Multimedia over IP — IMTC Fall Forum – November 2002 – New York, NY, USA

  4. Internet Excitement • The industry consolidates • multi-vendor, media is ‘normal’ • rich tools: gateways, transcoding, analysis • Time-based media as easy as HTML etc. • Content is still minor compared to HTML • standards make it much safer to deploy 3G & Multimedia over IP — IMTC Fall Forum – November 2002 – New York, NY, USA

  5. 3G Excitement • Look at the picture phones, etc. • Lots of uses: • short messages with audio/video • personal, news, updates • music download or message • image browsing Nokia 3650 3G & Multimedia over IP — IMTC Fall Forum – November 2002 – New York, NY, USA

  6. Where are we? • Internet: MPEG-4, ISMA, etc. • industry maturity • common formats • deploying now • 3G • 3GPP has mature, tested specs • yes, 3G networks are rolling out slowly • but, expect 3G services on 2/2.5G networks • messaging and download will lead streaming • bandwidth, billing, reliability, utility, content… 3G & Multimedia over IP — IMTC Fall Forum – November 2002 – New York, NY, USA

  7. The technical foundation Formats Codecs Protocols 3G & Multimedia over IP — IMTC Fall Forum – November 2002 – New York, NY, USA

  8. Transfer Protocols • HTTP – the classic download/browse • internet and cell-phone • MMS – MultiMedia Messaging • cf. the popular SMS, short (text) message service • cell-phone, with e-mail gateways with internet 3G & Multimedia over IP — IMTC Fall Forum – November 2002 – New York, NY, USA

  9. Streaming Protocols • ISMA and 3GPP use the same IETF protocols • Packet-switched streaming, PSS server client RTSP control over TCP Media Description in SDP form Media Streams in RTP over UDP 3G & Multimedia over IP — IMTC Fall Forum – November 2002 – New York, NY, USA

  10. Media File Format Motion JPEG 2000 Interoperable timed multimedia media formats MP4 version 1 3GPP MMS file format MP4 Version 2 MJ2 Version 2 3GPP MMS AVC & others... ISO Base Media File Format 3G & Multimedia over IP — IMTC Fall Forum – November 2002 – New York, NY, USA

  11. ISO File format features • Flexible usage: • authoring, composing, interchange, download… • Streaming support • ‘hint’ tracks tell servers how to stream • in a media-independent way • Extensible • Adoptible 3G & Multimedia over IP — IMTC Fall Forum – November 2002 – New York, NY, USA

  12. Codecs 3G & Multimedia over IP — IMTC Fall Forum – November 2002 – New York, NY, USA

  13. Codec Families • Classic video: • MPEG-4, Advanced Video Coding (AVC) • AVC aka H.264, JVT, H.26L, MPEG-4 Part10 • Wavelet • JPEG 2000 • Voice • Advanced MultiRate (AMR), WideBand (AMR-WB) • MPEG-4 CELP • Music – AAC 3G & Multimedia over IP — IMTC Fall Forum – November 2002 – New York, NY, USA

  14. Commonality between ISMA & 3G • File formats • the ‘MP4’ family • Protocols • IP/IETF – HTTP, RTP etc. • Codecs • MPEG-4 Video 3G & Multimedia over IP — IMTC Fall Forum – November 2002 – New York, NY, USA

  15. Interworking 3G and ISMA • Phones have limits – file size, streams etc. • Voice codec – CELP vs. AMR • Video codec – may need H.263 • Lots in common • very close to author once, play anywhere • one tool set, one server 3G & Multimedia over IP — IMTC Fall Forum – November 2002 – New York, NY, USA

  16. Standards and where to find them MPEG-4 ISO/IEC 14496 www.iso.ch IETF www.ietf.org ISMA www.isma.tv JPEG 2000 ISO/IEC 15444 www.iso.ch ITU www.itu.int 3gpp www.3gpp.org 3gpp2 www.3gpp2.org m4if www.m4if.org 3G & Multimedia over IP — IMTC Fall Forum – November 2002 – New York, NY, USA

  17. Summary Convergence of specifications Bandwidth, CPU, compression Device capability, deployment Interoperability The Media World is an exciting world 3G & Multimedia over IP — IMTC Fall Forum – November 2002 – New York, NY, USA
