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 W3C defines 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
