说明：  本文简单介绍了DirectShow技术，研究了利用DirectShow实现视频采集、压缩和网络传输技术。并利用第三方提供的编解码器实现了MPEG-4视频数据的网络传输系统，在该系统中利用RTP协议进行视频数据传输，同时实现了远端帧率的控制。
(This article briefly introduce the DirectShow technology, research realize the use of DirectShow video capture, compression and network transmission technology. And make use of third-party codecs realize the MPEG-4 video data transmission system network in the system using RTP protocol for video data transmission, at the same time realize a remote framerate control.)
