Picture signal distributor

Abstract

Abstract PURPOSE:To display a picture signal outputted from a computer onto plural monitors by providing plural sets of buffer amplifier circuits amplifying plural picture signals and producing outputs from each set of the circuits in parallel. CONSTITUTION:An output of the computer A is inputted to all monitor CRTs by switching switches 2d, 6d and 10d, but an output of the computer B is inputted to monitors 3b, 4b and 5b only. This is similar to computers C, D. When the changeover switches 2d, 6d and 10d are thrown to the right contact position, simultaneous control is attained and when the switches are thrown to the left contact position, the decetralized control is attained. Thus, the picture signal outputted from the computers is displayed on the plural monitor CRTs by controlling optionally the switches 2d, 6d and 10d so as to constitute a useful viewing and listening education system.
