摘要
设计与实现了一种基于H.264的多传输模式IP网络视频监控系统,该系统采用ARM9S3C2440作为核心硬件处理器,USB摄像头采集到的视频数据经X264压缩编码后由RTP实时传输协议进行网络层的打包,并通过ARM-Linux开发平台与PC机之间建立的U/DP Socket在有线以太网、无线Wi-Fi和电力线三种环境中进行网络传输,PC机在接收到视频流后进行解码与实时显示.最后,对系统服务器端的压缩编码效率和三种传输模式下的系统性能进行了测试和分析,测试数据结果表明该系统具有功耗低、压缩编码效率高、视频画质清晰等特点,并且能在不同的传输环境中保证视频传输的高实时性.
This paper designs and implements the multi-transport mode IP network video monitoring system based on H.264. The ARM9 S3C2440 is used as the system core hardware processor. Video data is captured by the USB camera and encoded by X264. The encoded video data is packed in the network layer by RTP and transmitted in Wired Ethemet, Wi-Fi and Power Line by UDP Socket which is established between ARM-Linux development platform and PC. After receiving the video stream, PC will decode and real-time display. Finally, compression coding efficiency in the server and system performance in three transmission modes are tested and analyzed. The test data and the results show that the system has the advantages of low power consumption, high compression coding efficiency and clear video quality, etc. And it can ensure the high real-time video transmission in various transmission environments.
