摘要： 基于网络的多媒体监测系统具有对现场信息的实时采集编码的能力，因而应用极其广泛。但是在具有网络传输特性的嵌入式平台上实现多媒体信息编码能力具有较大的实现难度，成为该类系统实现的难点之一。该文提出一种解决方案，着眼于实时性、可测量性以及低功耗性进行了嵌入式节点的优化设计以满足系统需求。该优化设计方案在实际实验中取得了良好的效果，对其他类似系统亦具有重要的参考意义。

Abstract: The multimedia monitor system over network for its capture and encoding ability for real-time information has good application. But the implementation of the real-time multimedia encoding system is hard to realize. A network aware solution is proposed. The approach has earned a good performance in the experiment, and has the reference mean to the similar systems as well.
