This paper proposed a technique of bit-rate control for video streaming over constant bit-rate communication channel, where the MPEG-2, standard variable bit-rate (VBR), is adapted to be used as a constant bitrate (CBR). The target image quality and by feedback based on the buffer level controlled on the output rate of the video encoder. A CBR transport over networks, result is a good performance compared with that of VBR. It introduced simplicity of network monitoring and analysis, where the VBR video streaming over CBR channel can be adapted to avoid the problem of congestion of the network. In this paper we study important issue of adapted VBR-compress the video for transport over a CBR channel. That developed systems are implemented using Matlab (Ver 8.1) under Windows 7 operating system.
