摘要 误码掩盖是在无线信道进行低速率视频传输的一种抗误码技术。本文在比较和分析了现有几种误码掩盖方法优劣势后,提出了一种混合误码掩盖法。该算法在没有过多增加解码端运算复杂度的同时,大大提高了恢复图像的质量。 Error concealment is a kind of anti-error technique applying for low bit rate video in wcirless channel. This paper presented a hiberd Error Concealment methed after comparing and analyaing several error concealment. This method improved the qulity of the video so far without adding much more complicating.
