【Abstract】 A novel intelligent video switching matrix is designed by using MAX456 as the switching circuit and by using AT89C51 as the control unit. By means of oftware control, the video switching matrix can work in many modes such as real-time, time-lapse and group control. Finally, application example is given and the main issues that need to be considered in hardware debugging are pointed out.更多还原
