| Abstract: | With two TI special video processing chip TMS320DM642 , a multi-channel video surveillance system is designed. DSP1 and decoder chip SAA7113 are used to capture multi channel videos and mosaic into one channel of video output. DSP2 is used to complete the capture, compression and transmission of the video output by DSP1. The scheme has flexible structure and good expandability. It can capture and transmit four channels of video in real time. |
