摘要 经典视频压缩码流的低抗错性、传统抗误码工具的"悬崖"效应以及分布式信源编码的高稳健性,决定了基于分布式视频编码(DVC)的视频压缩码流易错信道的抗误码传输机制与关键技术具有良好的应用前景。基于此,分析了分布式视频编码的容错传输原理,并对其中关键技术的最新进展进行了综述,最后给出了结论和今后的研究方向。 The key technique of the robust transmission for compressed video bit-stream over lossy channels will have turned to a scheme based on distributed video coding, due to the error-prone of compressed video signals, the ＂cliff effect＂ of classical error-resilient tool and the high robust of distributed video coding. The applications of Distributed Video Coding （DVC） in error-resilient video transmission are introduced and the advances in key techniques are reviewed. Finally, the conclusion is given out and the further research is pointed out.
