Abstract: The invention provides a method for a multimedia server to dynamically adjust the data rate that is streamed over an error-prone bandwidth-varying wireless network to a mobile multimedia client in a client-server architecture. The method enables multimedia applications to efficiently utilize the available (yet time-varying) wireless channel bandwidth and helps prevent interruption in the streaming due to client buffer underflow and packet loss due to network buffer overflow, hence significantly improving the multimedia streaming performance.

Abstract: A method and device for producing and delivering constant quality digital video bitstreams over channels of any bit-rate and variability are provided. The method and device may be applicable to any standardized video coding system, but preferably within the MPEG-4 standard. For constant capacity networks, the method and the device re-distribute the coded bits in a constant-quality variable bit-rate bitstream to construct a constant bit-rate bitstream. For variable capacity networks, the method and the device achieve constant quality as described by a metric that incorporate both spatial and temporal visual quality. The method and the device incorporate user, network, and channel parameters in controlling the bit-rate while encoding video material.
