使用本文提出的抗误码方法大大提高了恢复视频的质量.另外

该算法与H.263标准兼容

且没有过多增加信道负担和运算复杂度

具有实用价值.

Abstract

Based on PEI domain

this paper proposes a novel error-resilience technology for H.263 video transmission.It includes adaptive forward error-correction

error concealment and error-propagation prevention algorithms utilizing PEI domain.Simulation results show that the video quality is obviously improved using proposed technique over variable and error-prone channels.Furthermore

these algorithms are compatible with H.263 standard

and the presented technology has been used in practice.
