  • Motion estimation method and system for MPEG video streams
    Publication number: 20040013199
    Abstract: The present invention discloses a motion estimation method for MPEG video sequences. The method makes use of a global motion estimation algorithm to determine a set of dominant motion components. A simultaneous Full Search Block Matching (FSBM) search is conducted utilizing each dominant component for every block in a current frame. The results of each FSBM search are then compared to determine the best motion vector.

  • Method and system for symbol binarization
    Publication number: 20040008769
    Abstract: The present invention is directed to an improved method for the binarization of data in an MPEG data stream. The invention makes use of unary binarization to create codewords up until an index threshold. Once the threshold has been met, succeeding code symbols have appended to them an exp-Golomb suffix. This hybrid binarization scheme reduces the number of binary codewords to be processed by a Binary Arithmetic Coder (BAC), thus reducing the computation required by the BAC.
