摘要 介绍了一种实时MPEG-2以太网传输系统的设计方案,它由硬件MPEG-2编/解码卡和基于ARM处理器的嵌入式系统卡构成,前者用于视音频的实时压缩编码和解码,后者将MPEG-2数据流进行IP封装和解封装,还分析了IP网络传输对接收端MPEG-2解码视音频的影响,并设计了一些测评方法对系统进行了相关测评。 This paper introduces the design of an real-time MPEG-2 transport system over Ethernet. This system is composed of hardware MPEG-2 encoder/decoder and embedded system card based on ARM processor. The former is for realtime compression of AV, and the latter is for IP packing and unpacking. The paper analyses the impact of IP network transmission to the video/audio of MPEG-2 decoder, and provides some measurement methods for the system.
