面向Android客户端的无线视频监控系统设计

摘要

Aiming at demand of getting video surveillance whenever and wherever possible in application process of smart home,a wireless video surveillance system for Android client was designed on the basis of ARM embedded platform. The system supports wireless relaying transmission,possesses an ability of peer⁃to⁃peer(P2P)connection with dynamic address,acquires and transmits video data as required. The H.264 video coding technology is adopted in the system. The real⁃time transport proto⁃col(RTP)and IEEE802.11g protocol are used to transfer the encoded data. Surveillance video can be gotten with wireless local area network or Internet. An experimental demonstration platform was built to test and analyze the performance of the system. The results show that the system can be flexibly deployed,the accessed monitoring video is clear and stable,and the wireless video surveillance system can meet the requirements of video monitoring for smart home in the wireless network environment.%为了满足智能家居应用中随时随地进行视频监控的要求，基于ARM嵌入式平台，设计一种面向Android客户端的无线视频监控系统，该系统可实现无线中继传输，具备端到端动态地址连接能力，并按需采集传输视频数据。系统采用H.264视频编码技术，基于实时传输协议和IEEE 802.11g协议传输数据，可通过无线局域网或互联网获得监控视频。通过构建实验演示平台进行了系统测试和分析，结果表明该系统部署灵活，获取的监控画面清晰稳定，可以满足无线网络环境下家庭视频监控的要求。
