摘　　要：在介绍MPEG-4抗误码工具原理的基础上,分析了基于MPEG-4标准采用的几种视频编码纠错方法。采用数据分类的打包机制以及可逆的VLC编码,提出一种低复杂度抗误码模式,有效降低了抗误码处理所需的系统资源。用这些方法使得压缩的视频数据能够在无线信道中有效地传输。This paper go deep into the research of the technology about error resilience for video transmission based on the MPEG- 4, some available methods about error correcting code are presented, then proposes a low-complexity architecture of MPEG-4 error resilience mode, which reduce availably the system cost of error resilience processing. Compressed video can be transmitted efficiently through wireless channel by these methods.
