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.
