Abstract
PURPOSE: To make it possible to monitor efficiently a required camera output by the small number of monitor TVs, by performing both of camera switching and line switching simultaneously in the ITV system.
CONSTITUTION: Plural terminal stations 1 having plural ITV cameras 2 and camera switching parts and monitor TVs 5, which are provided in center 4 and have the number smaller than the total number of ITV cameras, are connected through line switching part 10, which switches the connection between video transmission busses 12 from camera switching parts 3 and video transmission busses 11 corresponding to monitor TVs 5, correspondingly to each camera switching part 3. Then, the operation of switching between camera switching parts 3 and line switching parts 10 is performed by the instruction from control part 9 provided in center 4, so that the video transmission between desired ITV camera 2 of desired terminal station 1 and a desired monitor TV can be performed.
