已有的CAVLC解码方法包括二叉树解码方法、全码表解码方法和Hashemian解码方法等，但是这些解码方法都只关注解码性能的一个方面：解码速度或存储空间，因而无法有效地提高整体性能。针对这一问题提出了一种快速的解码方法。该方法通过自动码表分配技术和码表地址转移技术来提高限定存储空间条件下的解码速度。实验结果表明，使用相同的存储空间，该方法的速度是传统解码方法的1.5倍，更加适用于H.264标准。

CAVLC decoding methods known by people include bintree, full code table, and Hashemian decoding methods, etc. all of which lay emphasis on only one aspect of decoding: decoding speed or memory space, and thus the general capability can not be improved effectively. In view of that, the paper puts forward a new and fast decoding method which by means of the automatic distribution of the code table and the transfer of the code table address, improves the decoding speed in the limited memory space. As the experiment shows, in the same-size memory space, the speed of this new method is 15 times as fast as that of the tradition ways so that the new one is more suitable to H.264.
