摘要：This invention provides an adaptive transcoder which streams predictive codedvideo data over variable bandwidth networks and to devices having varying processing

capabilities. The invention dynamically and continuously determines an available networkbandwidth and a client device's processing capabilities. This invention uses bit streamtranscoding of video data to reduce the bandwidth required to stream the video. Certainframes of a bit stream are replaced with Pseudo-P frames according to the results ofrate control feedback and frame ranking. The invention thus transmits a single MPEGstream to multiple devices having varying capabilities and does not add redundancy intothe network.
