TELECOMMUNICATION SYSTEM FOR TRANSMITTING FULL MOTION VIDEO

摘要

A telecommunication system (10) is provided allowing the transmission of full motion color video, voice and data signal over a twisted pair of wires currently utilized only for voice and data communications. The signal is transmitted over a twisted pair link (16) as a broadband signal up to a distance of six thousand feet. The broadband signal received from the twisted pair link (16) is amplified and an impedance proportional to the impedance of the twisted pair link (16) and vectorially opposite thereto is impressed thereon. A unity gain is achieved whereby the signal degrading effects of the impedance of the twisted pair link (16) are reversed resulting in the accurate reproduction of a video signal over significant lengths of the twisted pair link (16). Moreover, the compensation for twisted pair impedance allows accurate reproduction of broadband signal, a plurality of different video, telephone and data signals can be multiplexed together and transmitted simultaneously over the same twisted pair link (16).
