Abstract:
A system for transmission of analog color video signals between a source of said signals and a video monitor, being at spaced locations, comprising:a plurality of computers, each providing, as a set, said color video signals;a switch receiving said sets of said color video signals, each with respect to a common reference, from said computers and providing a selected said set of said color video signals as an output;a signal transmitter at a first location responsive to said output of a set of said color video signals, said transmitter, including an amplifier for each said color video signal of one of said sets for providing a color video signal output and wherein at least a high frequency portion of each said color video signal has been amplified as a direct function of frequency and providing both an inverting and non-inverting signal, available as an output;a plurality of video transmission circuits, each said circuit having first and second ends, respectively, one circuit for each of said color video signals of one of said sets and each said circuit having an input responsive to an output of said transmitter at said first end, and each said circuit having a responsive signal output at said second end;a signal receiver at a second location responsive to each of said transmitted signal outputs and color video signal at said second end, including an amplifier for each said color video signal for providing a discrete color video signal with respect to a common reference; andsignal means responsive to said receiver for providing each said color signal, each with respect to a common reference, to an analog color video monitor.
