前文参考之适应性二元算术编码（CABAC），CABAC的设计概念，对于发生机率 > 0.5 的事件有效地编码，改进了传统霍夫曼编码法需要大量的乘法运算的问题，而在效能与压缩效率上取得相当大的改善空间。-CABAC design concept, for the incidence of> 0.5 events efficiently coding, Huffman coding to improve the traditional method requires a large number of multiplication problems, and to obtain considerable room for improvement in the performance and compression efficiency.
