摘　　要：随着通信技术、网络技术、计算机技术的发展,传输信道的差错,不仅严重影响视频业务质量,甚至会使通信系统崩溃,因此差错复原技术就成为易发生差错信道下视频编码的重要组成.该文对目前各种新的视频编码标准中所应用的一些差错复原技术,如重同步;数据分割;可逆变长编码;图像分割;可伸缩视频编码;多描述编码;差错掩盖等的内容、原理进行了详细的叙述.并对信道模型进行了差错复原技术的实验.结果表明,在应用了差错复原技术后,重建图象的主客观质量均得到了明显的改善.With the development of communication technique, network techniques ,computer technology, error of transmission channel , not only ean dagages the seriously video service quality. But also makes communication system collapse. So technique is an important part . This paper the video coding signal channel of system gave a detail description of the content and principle of error resilience technique,such as resynshronization,datapartitioning reverisible variable length coding ,reference picture selection mode and error cocealment,which are use in diversified new video coding international standarda. This paper also gave some simulation results of error resilience technique based on MT - 2200 channel models. The results shows error resilience technique can remarkably improve the subjective and objective quality of the reconstruted image.
