Abstract
In this paper, we propose an efficient dynamic coding scheme by using multiple codewords in H.264/AVC entropy coding. The exponential Golomb (Exp-Golomb) codewords used in H.264/AVC do not reflect enough the symbol distributions of the combined syntax element in (7) due to their static probability distribution characteristics. However, the multiple codewords in this paper have different statistical characteristics. we propose a dynamic coding scheme by using selectively among multiple codewords to encode the combined syntax element according to given image sequences. Simulation results show that our proposed scheme outperforms the existing (7) method in compression efficiency without loss of quality.
