Abstract :
In this paper, we show a design method for a multi-channel communication system for MPEG video that is based on adaptive QoS control. The relation between the SNR degradation and the coded bitrate in each scene of a video channel is approximated by linear equation. The bitrate is allocated to each scene based on a linear equation. However, if the number of channels increases, the bitrate is not allocated appropriately because the scenes change frequently. In this paper, we divide the video channels into groups. An optimum number of groups can be obtained by considering the scene characteristics. Furthermore, we also show experimental results of applying the method to a prototype system.
