An Effective Way of CAVLC Decoding Methods

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.
