The weight adaptation mode of the interference suppression filter is controlled by the signal-to-noise ratio of the current frame.
根据当前帧的信噪比决定自适应滤波器的权系数更新方式。

Most of the rate adaptation algorithms are about the data frame rate. However, the rate adaptation algorithm about the control frames is still very rare.
但目前绝大部分速率自适应算法是针对数据帧的速率进行自适应,而针对控制帧的速率自适应算法还很少见。

Motion Vector Refinement: Bit rate adaptation transcoding adapt the network heterogeneity, which makes the reference frame changed. The motion estimation is needed.
