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
