H.264/AVC 디코더의 움직임 보상을 위한 캐시에 적용된 프레임 재압축 알고리즘

This paper proposes a recompression algorithm designed to be integrated into a cache for motion compensation in an H.264/AVC decoder. Compression efficiency is improved by using unused storage space in neighboring blocks as well as the correlation with the neighboring pixels stored in the cache. The proposed algorithm is effectively used with a 32×32 cache, resulting in a PSNR improvement of 0.371 ㏈.
