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。
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.
同时基于图像信号的相关性、光滑性及一致性的假设，分别对MPEG-2的I-帧、P-帧和B-帧图像提出了相应的错误隐藏技术。
Statistical correlations of the smoothness and consistency in images were used to develop error concealment techniques for I-frame, P-frame, and B-frame MPEG-2.
该方法是在权衡考虑影响视频主观质量多种因素的基础上，并综合了传输、鲁棒性编码和解码端错误隐藏等技术的抗误码方法。
With weighting the factors of video subjective quality, it integrates the technology of transmission, robust coding and error resilience of the decoder.
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。
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.
