摘要
为了适应计算机网络技术、多媒体图像压缩技术以及数字通信技术的高速发展,研制了一种新型的网络化远程视频监控系统。介绍了该系统中基于嵌入式系统和Web服务器的视频监控服务器的硬件设计与实现。首先简要分析了远程网络视频监控系统的应用场景和工作原理,然后重点讨论了监控系统中视频监控服务器的组成以及三大模块的功能和硬件实现。该视频监控服务器主要解决了两个关键技术,即视音频数据的压缩编解码以及视音频数据的实时传输。实验取得了良好的监控效果,相信该系统会具有广阔的应用前景。
In order to adapt to the rapid development of the computer network technology, multi-medium image compression technology and the digital communications technology, a kind of new remote video control system using network was developed. The hardware design and realization of the kind of digital video control server based on embedded system and Web server was introduced. First, the application scenery and work principle of remote video control system were analyzed briefly. Then the structure of video control server was discussed. The function and hardware realization of three main modules were also represented in detail. The video control server designed by us mainly resolves two key technologies that are compression encoding and decoding of video and radio data and real-time transmission of those data .Using this system ,the experiment got good control effect.It was believed that the system has large application foreground.
