【Abstract】 This article analyses the main process of CABAC in H.264/AVC at first, then introduces two existing ways of improvingcoding efficiency. Finally, we propose a new fast arithmetic algorithm to enhance coding speed. The experiment shows that withoutdecreasing coding efficiency a lot, this fast arithmetic algorithm can improve coding speed to some extent as well as saving memory,so it is more likely to be used in scenes of having more real time requirements and less memory。更多还原
