An Improved Group-based Optimizing of CAVLC Decoder

摘要：

Variable length code is a general lossless entropy coding method that is widely used in video compress standards. Based on analyzing R. Hashemians fixed-length group decoding methods and the structure and statistic principles of CAVLC code words, this paper puts forward a kind of decoding method by dividing the CAVLC code words into prefix and suffix. The method has been proved to save 62.3％ memory and decrease the needed decoding speed more than R. Hashemians fixed-length group decoding methods.
