Rate at which video data is transmitted to the output device.
视频数据传输到输出设备的速率。
The input bit rate and the output frame rate of video decoder is fix, so a Rate Buffer is needed to balance this rate difference.
而经解码后显示的侦速率是恒定的，这就要求在解码端有一个缓冲器来实现输入码率与输出码率间的过渡。
Rate control techniques must then be employed to regulate and control the output bit rates of video sources in the network to achieve the best trade-off between quality and bandwidth utilization.
这就需要采用码率控制技术来调整并控制视频源的输出比特率，以获得在质量和带宽利用间的最佳均衡。
