Abstract
PURPOSE: To reduce the total amount of a video cable by taking in selectively only video signals in a prescribed horizontal raster part correspondingly to CRT units and taking out only derired video signals for every CRT unit as the output of a video signal amplifier.
CONSTITUTION: Composite video signals are applied to input terminal 13 and are supplied to CRT units 4 and 4'. Here, video signal suppressing circuit 19 is initialized by vertical synchronizing signal 21 generated in vertical synchronous circuit 21, and has a function to count horizontal synchronizing signals generated in horizontal synchronous circuit 20, and generates signals, which suppress the output of video signal amplifier 18 for every arbitrary number of horizontal rasters, by the control of selection circuit 24 which can be beforehand set for every CRT unit. As a result, only video signals in a prescribed horizontal raster part are selectively taken in correspondingly to CRT units, an only desired video signals are taken out for every CRT unit as the output of amplifier 18, so that the total amount of the video cable can be reduced.
