We also show that in the receiver error concealment and error resilience should be adopted for maximum using of the rightly received video stream data.
为了能够最大限度地应用已经接收的视频数据流，在接收端需要采用错误隐藏和错误恢复技术。
However, the compressed video streams are vulnerable to the random noise in channel and generate errors, therefore, error concealment in video communication draw more and more attention.
但是，压缩后的视频码流极易受到信道随机噪声的干扰而产生错误，因此，视频通信中的错误隐藏技术越来越多的受到人们的关注。
An error concealment algorithm is proposed as a post-processing tool at the decoder side, with the aim of recovering the motion vectors and image blocks lost during the video sequence transmission.
提出了一种误差掩盖算法，作为在解码器端的后处理工具，以恢复视频序列在传输过程中丢失的运动矢量和图像块。
