摘要
总结了视频图像中的差错控制技术及其最新进展。首先详细评述了3种基本的差错控制技术:基于编码器的差错弹性,基于解码器的差错隐藏,基于编/解码的交互式差错隐藏,然后总结了编码标准H.263+,H.263++,MPEG-4,H.264中的差错控制工具,最后指出了视频差错控制的研究重点和发展方向。
This paper reviews the error control techniques in video communication and its development in recent years. At first, these techniques are described in three categories： error-resilient video coding, error concealment in decoder, combined coder and decoder error concealment. Then the error concealment tools in H263 ＋, H. 263 ＋ ＋, MPEG-4, H. 264 are introduced. Finally, the paper tries to analyze the direction of the error control of video communication.
