Abstract

In this paper, we propose two methods to reduce computational complexity of H.264/AVC decoder. The proposed methods utilize CBP (Coded Block Pattern) information to skip inverse DCT transform and reconstruction processes for 8×8 blocks that have CBP bits being zero. Furthermore, we adaptively skip zero coefficients in a block to reduce unnecessary computation in inverse DCT transform module. Experimental results show that the proposed method can reduce decoding complexity by about 10 % with only a negligible PSNR drop.
