  • System and method for transcoding entropy-coded bitstreams
    Patent number: 9762932
    Abstract: A system and method for transcoding an entropy-coded bitstream is presented herein. The syntax elements of the entropy-coded bitstream are decoded and transcoded into a second format. The second format can comprise a simpler format for decoding. The foregoing advantageously alleviates the processing requirements for the video decompression engine.
    Type: Grant

  • System and method for entropy code preprocessing
    Patent number: 7305036
    Abstract: A system and method for preprocessing a bitstream of compressed video data is presented herein. The bitstream of compressed video data can include, for example, a bitstream in accordance with the MPEG AVC standard. The bitstream is received and modified by a preprocessor to facilitate multi-row decoding. The modifications to the bitstream can include identification of starting points of macroblock rows with row headers. Additionally, multi-row decoding is further facilitated by generation of decode descriptors which indicate the starting row positions in the modified bit stream. Additionally, the modified bit stream can be formatted in accordance with a simpler coding scheme to simplify decompression.
