嵌入式视频服务器的设计与系统实现

Design and Implementation of Embedded Video Server

设计了一种在嵌入式Linux上运行、在PC机网页客户端上进行监控的无线视频传输系统。通过嵌入式终端的视频服务器进行视频采集,然后将采集后的图像进行JPEG压缩,最后利用HTTP推送技术通过Wi-Fi发送到网络。为增加整个系统的可控性,将视频服务器与Web服务器BOA进行结合使用。这样通过Web服务器的CGI调用功能为嵌入式终端增加可控机制。最后以近年来人们较为关注的消防为背景,进行了系统实现。

This paper designs a wireless video transmission system which running on an embedded Linux and monitoring on the PCweb client.In detail.It captures video through the video server embedded terminal,and then it does the JPEG compress for the collected images.Finally,it sends the video with HTTP push technology to the network via Wi Fi.To increase the controllability of the whole system,it uses video server and WEB server BOA in combination.
