基于DM642的无线视频监控系统

针对难以安装有线网络场所的远程实时监控问题,采用了视频处理芯片DM642、视频解码芯片TVP5150A、CDMA无线收发模块DTU-800X等组成硬件终端,负责视频采集、MPEG-4编码压缩及发送,基于UDP协议设计高效视频传输控制算法,利用VC++编程及directshow组件开发客户端软件,实现了无线实时视频监控功能。实验结果表明,该系统具有传输效率高、体积小、安装方便等特点,适用于各种监控场合。

Wireless video monitoring system based on DM642

Aiming at real-time monitoring of those sites were difficult to install cable network,using video processing chip DM642,video decoder chip TVP5150A,CDMA wireless transceiver module DTU-800X,etc,the hardware was designed to capture,MPEG-4 encode video compress and video data send.An efficient transmission algorithm based on UDP protocol was proposed.The client software was developed by VC++ based programming and directshow components.The test results indicate that the system has a high transmission efficienc...
