Study on error-resilient video transmission for distributed remote video monitoring system
Author(s): 
Pages: 49-54
Year: Issue:  2
Journal: JOURNAL OF THE CHINA RAILWAY SOCIETY

Keyword:  视频监控差错恢复视频编码视频传输;
Abstract: 介绍了分布式视频监控系统的结构,比较了MPEG-1、Motion-JPEG、H.263视频压缩标准的特征和适用范围,分析了视频图像运动补偿混合编码原理以及差错扩散的原因.本文重点研究了视频差错重同步、数据恢复和差错掩盖(error concealment)控制策略,实现了视频解码中的差错恢复(error-resilient)算法,提高了解码算法的健壮性(robustness),增加了监控系统的差错控制能力.最后对分布式远程视频监控差错控制的研究方向进行了展望.
