  20. Standards for Mobile Multimedia

  21. Why are Standards Needed? • Enable interoperability between devices from different vendors • Enable content to be authored once, in a single format and distributed through various wireless systems • Enable development of innovative applications and services based on standard, fully-defined systems

  22. Don’t We Have Enough Standards? • A single standard that defines an end-to-end system of multimedia delivery over wireless channels is required • ISO/MPEG defines compression, scene description, control APIs but not transport • IETF defines transport only • ITU defines multimedia communication only • W3Cdefines standards for web content • 3GPP defines standards for GSM systems only

  23. Components of an End-to-End Framework • Codecs • Audio, Video, Image, Text, ... • Transport protocols • Capability Exchange • Session Initiation, Media Description • Media Control • File Format

  24. The Standards Gallery

  25. MPEG-4 H.263 AMR AAC MP4 GIF JPEG XHTML SMIL RTP/RTCP RTSP/ SDP HTTP UDP TCP TCP/IP GPRS/EDGE/W-CDMA 3GPP Packet-Switched Streaming Framework (TS 26.234)

  26. 3GPP Circuit-Switched Video Telephony Framework (3G-324M) MPEG-4 H.263 AMR G.723.1 H.263+ H.261 H.245 User Data H.223 Circuit-Switched UMTS

  27. The MPEG-4 Standard • MPEG-4 Visual • Natural Video • Simple Profile • Simple Scaleable Profile • Core Profile • Main Profile • ... • Synthetic Video • Face Animation • Body Animation • 2D/3D Mesh • Sprites • MPEG-4 Audio • Natural Audio • AAC • TwinVQ • CELP • HVXC • HILN • Synthetic Audio • Text To Speech • General MIDI • Synthesis • MPEG-4 Systems • MP4 File Format • BIFS • Sync Layer • FlexMux • DMIF • MPEG-J • IPMP • OCI

  28. Q&A
