Director switching stationIt is a device for editing and combining multiple TV signals. During on-site production, the video signals from multiple cameras are all sent here for real-time editing. The director switching station is actually an electronic switch combination that can control the on/off of various video signal circuits through buttons, with the on output and off cutoff. The director switching station can also be replaced by a stunt signal generator. The broadcasting station should have at least 56 monitors. The 14th monitor is called the channel monitor, which is specifically used to display images of various signal sources for guidance and monitoring purposes. The program output signal of the broadcasting station is output on one hand, and displayed on the output monitor for the broadcasting supervisor to monitor on the other hand.

The A bus and B bus of the broadcasting station are pre selected signal lines for stunt transformation. Two signals that are about to undergo stunt changes can be determined on two separate lines. Only one key is allowed to be pressed on any wire harness, which means that only one signal source can be selected on the wire harness. If another key is pressed, the previously pressed key will immediately pop up. The signal output depends on the position of the control lever in the center of the panel. Since direct switching is a form of instantaneous transition of the lens, simply press the corresponding key to switch based on the content displayed on the channel monitor when the A bus or B bus is conducting. There are five special effects available on small broadcasting platforms: one is the slow conversion method; The second is to use a vertical left and right stroke method; Thirdly, it is done in a horizontal line and down transition manner; Four and five are drawn in the form of corner block patterns.
