First, horizontal sync signal and field sync signal from the video signal are separated, then control signal according to the sync signal by DSP and FPGA is generated to control the switching between multiple video channels. Thus, it achieves to make a video processor to monitor different place. Experimental results show that the method can realize video channel switching reliably, and is applied in the video monitoring warning system successfully.
