Abstract

Aimed at design of high reliable video monitor systems and the problems of large video data transmission, a video network monitoring system is designed. The system based on TMS320DM642 chip as the core and combined with TVP5150A and SAA7105 chips as the video decoder/encoder. The specific structure of DM642 chip and DSP/BIOS system design are described. The design of the system hardware, microdriver development and realization of software modules are detailed. In the final, some solutions are given for the problems encountered in the actual design, then the system of future applications and expansion capabilities are introduced.
