Video decoding apparatus

摘要

A decoding apparatus lightens the load incurred by padding processing. When the decoding apparatus outputs decoded data to a frame memory, a padding unit in the decoding apparatus j udges whether the decoded data includes boundary pixels, and when boundary pixels are judged to be included, performs padding processing to an extension area using boundary pixel data. As a result, as well as pixels in one decoded macroblock being output, when boundary pixels are included in the output macroblock, the boundary pixels are output to the extension area. This eliminates the need to re-read the boundary pixels from the frame memory.
