Abstract :
In this paper, we present a dynamic bandwidth allocation scheme which allots available transmission rate to each video source in proportion to its traffic. While individual elementary streams are encoded with limited VBR, the bit rate of multiplexed bit streams can be CBR or VBR depending on the transmission networks. The simulation result shows improvement more than 1 dB in average PSNR and smaller variance in PSNR compared to the CBR video sources among multiplexed different video sources. This scheme is able to be applied to satellite or terrestrial broadcasting as well as ATM transmission
