基于SoC的MPEG-2解码纠错功能实现

摘要

At present, Mpeg-2 is video standard widely used in video communication, because of its using VLC coding,the importance of each code flow bits was increased, and in some complicated transmission environment, a lot of noise would brought, it was great influence for the quality and finish of the video decoding. So the error detection and cover technology were very important in MPEG-2 video decoding. In this article, noise detection of mpeg-2 decoder and method of error covering and its realization were mainly discussed.%　　MPEG-2是目前在视频通信中广泛应用的视频标准，由于其使用了VLC编码，增加了每个码流比特的重要性，而在某些复杂的传输环境中会引入很多噪声，这对视频解码的质量和完成都是有很大影响的。所以错误检测与掩盖技术在MPEG-2视频解码中非常重要。文章主要讨论MPEG-2解码器的噪声检测与错误掩盖的方法及其实现。
