摘要
针对目前的局域网视频监控传输系统,以嵌入式Linux操作系统为平台,应用用户数据包协议(UDP,User Datagram Protocol)穿越网络地址转换(NAT,Network Address Translation)技术,设计了远程视频监控系统。该系统由2部分组成:发送端和接收端,由于2者分别处于不同的内网中,无法直接通信,故采用UDP穿越NAT技术,搭建公网服务器以协助双方建立连接并传输视频。经测试,该方案可以较好地穿越NAT,并且在接收端电脑上能实时的显示视频图像。
A remote video monitoring system is designed,which adopts the technique of User Datagram Protocol（UDP） through Network Address Translation（NAT）.Based on the current video monitoring and transmission system over Local Area Network（LAN）,it depends on the embedded Linux operating system as the platform.This system is composed of two parts： the sender and receiver.However,for two these two parts are in different subnets,this makes it impossible to connect with each other directly.So the system,with the technique of User Datagram Protocol（UDP） through Network Address Translation（NAT）,builds up the public network server and thus assists both sides to establish the connection and transmit the video.The experiment indicates that this solution has a fairly good traversing of NAT,and also a real-time display of video images on the computer of the receiver.
