Abstract: 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 efficiency, as well as small size and easy installation. It is suitable for various monitoring occasions.
