摘　　要：H.264视频压缩技术在传输过程中由于物理信道的的损伤会引入噪声,本文通过纠错控制机制提高H.264编解码的适应性。本方法适合在空间信道不稳定、码流易丢易错的情况下使用,便于硬件实现。For physical channel damage, H.264 video compression technology introduces noise into transmission. This paper improves the adaptability of H. 264 coding and decoding through error correction control mechanism. This method is suitable for use in the case of unstable space channel and error-prone bit stream, and it is easy for hardware implementation.
