Abstract

PURPOSE: To reduce a cost by reducing the mumber of transmission lines by providing plural TV cameras arranged at plural monitoring points, and a means to send video signal selectively from the TV camera together with an identification signal.
CONSTITUTION: Identification code attaching devices 14-16 are connected to the TV cameras 11-13, respectively, and an (identification code + video signal) is sent from each camera to each input terminal of a matrix switch(SW) 21. A synchronizing and separator circuit 22 separates a synchronizing signal from the video signal from the output terminal of the SW 21, and inputs it to a genlock circuit 24 together with a reference signal S2 arriving from a control signal generator 23. The circuit 24 performs the phase synchronization of the signal S2 from the generator 23 with the synchronizing signal separated from the video signal, and locks the video signals of the cameras 11-13 with the signal S2 completely. In such a way, the timing of a control signal S1 to switch the SW 21 can surely be performed by the end timing of the video signal, and the signal can be transmitted via one transmission line 30.
