  • Piecewise processing of overlap smoothing and in-loop deblocking
    Patent number: 8576924
    Abstract: A video processing apparatus and methodology are implemented as a combination of a processor and a video decoding hardware block to decode video data by performing piecewise processing of overlap smoothing and in-loop deblocking in a macroblock-based fashion. With this approach, a smaller on-board memory may be used for the in-loop filtering operations of the video decoding hardware block. By pipelining the piecewise processing operations, latency in the filtering operations is hidden and the filtering output is smoothed, thereby avoiding the need for bursts of fetching and storing of blocks.
    Type: Grant

  • Scratch pad for storing intermediate loop filter data
    Patent number: 7792385
    Abstract: A video processing apparatus and methodology are implemented as a combination of a processor and a video decoding hardware block to decode video data by providing the video decoding block with an in-loop filter and a scratch pad memory, so that the in-loop filter may efficiently perform piecewise processing of overlap smoothing and in-loop deblocking in a macroblock-based fashion which is a much more efficient algorithm than the frame-based method.
