摘要
文章介绍了视频编解码标准H.264解码器的解码流程,并分析了解码器中的熵编码原理与过程,针对解码过程中所查码表的特点,提出了把码表适当分块来缩小其查表范围的优化方法,从而提高解码器在熵编码过程中的解码速度,以满足实时性的要求。
In this paper, the decode flow of the H.264 decoder has been introduced,and the process of the entropy coder in the decoder has been analyzed. An optimize of deviding blocks to lessen the searching range has also been brought forward, so that the decoding speed of processing the entropy coder is greatly increased.
