    This invention relates to a switching matrix technique for multi-channel TV and various graphic equipment to dispatch video signals. This dispatch station is composed of PC video interface circuit, switching matrix and amplifying-driving circuit, which constitute a video switching matrix unit circuit which is corresponding to an output, each output having 8 R, G, B video signal input sources. The TTL video signal from PC is converted into R, G, B video signals through PC video interface circuit. The video switching matrix completes the unified switching to these signals, which is output to display via amplifying-driving circuit.
