:文章介绍了在局域网有关AVI文件视频流的实时操作中如何获取AVI视 频流，利用系统压缩管理器实现视频压缩，并实现视频图像的快速显示等问题。具体 讨论了在利用UDP协议进行数据传输时平滑突发数据流、恢复接收数据包的次序 等问题。(: This paper introduces the relevant AVI file in the local area video streaming real-time operation How to obtain the AVI video stream, using System Manager to achieve compression video compression, and to achieve rapid display video images and so on. Specifically discussed the use of UDP protocol for data transmission when the unexpected smooth data flow and restore order to receive packets and so on.)
