Abstract

We present a new algorithm for VLC table prediction in H.264 context-based adaptive variable length coding (CAVLC). Using both the correlation of coding modes and the statistics of the mode distribution in intra and inter frames, we can predict an appropriate VLC table of the given $4{\times}4$ block. Experimental results demonstrate that the proposed algorithm reduces the bit rate about 0.97% on average, compared to the H.264/AVC standard.
