Abstract
A video signal processing apparatus enabling reuse by a previously used internal configuration, provided with a storage device for storing the states of all or part of the intersections of a matrix switch to the output side of which inputs of video signal processing units and video signal output channels are connected and an intersection reproducing device for setting intersections of the matrix switch in accordance with the content of the storage device. When using current settings of the matrix switch, the current settings are stored in the storage device. When it is desired to reuse the apparatus after using it in different settings, the intersection reproducing device is activated. Therefore, an operator no longer has to repeat an operation for setting each and every intersection and can obtain the desired settings by activating the intersection reproducing device.
