Abstract:
An extended-in-length computer video communications link for transmitting computer video signals comprising:a source of computer video signals including red, green, and blue video signals,a video transmitter comprising a plurality of amplifiers, one of each said amplifiers for each of said red, green, and blue video signals, each said amplifier comprising:a signal input for receiving a one of said red, green and blue video signals,frequency sensitive compensating circuitry responsive to a said video signal so that said amplifier provides a first video signal that increases in amplitude with increasing frequency at a first output and a second video signal that is an inverse of said first video signal at a second output,a twisted pair of conductors for each said amplifier, with first and second conductors of said twisted pair coupled at one end to respective said first and second outputs of said amplifier,an adapter for each of said twisted pair of conductors, each said adapter coupled to an opposite end of a respective one of said twisted pair of conductors, each said adapter receiving said first video signal and said second video signal and providing a respective said video signal as a single ended output, and further configured to provide a ground reference potential for said transmitter at said adapter, whereby need for a reference ground conductor between said transmitter and said adapter is eliminated.
