為了擴大監控范圍,提高資源利用率,降低系統成本,提出了一種多通道視頻切換的解決方案。首先從視頻信號分離出行場信號,然后根據行場信號由DSP和FPGA產生控制信號,控制多路視頻通道之間的切換,從而實現讓一個視頻處理器同時監控不同場景。實驗結果表明,該方案可以在視頻監控告警系統中穩定、可靠地實現視頻通道的切換。 Abstract: To expand the scope of monitoring, improve resource utilization, reduce system cost, a multiple video channels signal switching method is pointed out in this paper. 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.
