Why are standards needed
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


Don t we have enough standards
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


Components of an end to end framework
Components of an End-to-End Framework

  • Codecs

    • Audio, Video, Image, Text, ...

  • Transport protocols

  • Capability Exchange

    • Session Initiation, Media Description

  • Media Control
