ISDBにおける符号化画像の効率的多重方式の検討

抄録

In ISDB (Integrated Services Digital Broadcasting), it is necessary to multiplex video, audio, and other data services efficiently, in consideration of the requirements for real time capability and the quantity of coded data for each services. For the video coding, VBR (variable bit rate) method is better than CBR (constant bit rate) method from the view point of efficient using of channel capacity. In this paper, the Peak-Rate-Constant-VBR method is proposed for the MPEG2 videos multiplexing into a transmission line with a restricted capacity, together with other data services. And the effectiveness of this method is discussed.
