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。
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.
本文证明了对IIR信道输出进行过采样(采样率是输入码率的整数倍)可以转化成单输入多输出的多信道模型，并且不同的信道有相同的AR系数。
In this paper, we prove that oversampling the output of IIR channels can be transformed into a single input multiple output (SIMO) model, and the subchannels have the same AR coefficients.
