  • Network-aware adaptive video compression for variable bit rate transmission
    Publication number: 20050002453
    Abstract: In a method of transmitting video data over a packet network, an input video stream is fed to a compressor that generates a compressed output stream. The compressor determines a target bit rate for the output stream based on desired picture quality. A traffic management unit a determines the available bit rate for the compressed data stream based on network condition. The output is adjusted if the target bit rate exceeds the granted bit rate.
