Abstract
This paper proposes the new coding rate control method in MPEG-2 video scalability. First of all, we investigate the efficiency of SNR scalability from the relations between hierarchical allocated bits and picture quality. Next, base on the the efficiency, we propose the new coding rate control method which has the dynamic controlling of bits allocation ratio. From the simulation experiments, we show the effectiveness in comparison to MPEG-2 TM5 rate control method.
