Transmitting scalable MPEG video over a wireless network

摘要

A system and method for transmitting scalable MPEG video streams over a wireless network by determining a base stream and one or more enhancement streams for each MPEG video stream, determining the available capacity of the network for transmitting the video streams, selecting which of the base streams and which of the enhancement streams should be assigned for transmission during a contention free period over the network according to the determined available capacity of the network; and placing said selected base streams and any selected enhancement streams of the scalable MPEG video ready for transmission during a contention free period over the network; and placing any remaining base streams and any remaining enhancement streams of the scalable MPEG video ready for transmission during a contention period over the network.
