Twisted pair communications line system

A video color signal transmission system comprising:

• a plurality of selectable sources of sets of video color signals, each set selectable for transmission and including red, green and blue video color signals,
• a plurality of transmitters, one of each for one of each of said red, green and blue video color signals of a selected said set, each said transmitter including:
• a single ended to balanced signal converter responsive to each said video color signal, thereby providing sets of balanced red, green and blue video color signal outputs,
• a transmission cable comprising:
• a plurality of twisted pair communications lines, each twisted pair communications line having a first end and a second end, said first end of each said twisted pair communications line coupled to a one of said balanced video color signal outputs and said second end of each said twisted pair communications line providing a balanced one of said red, green and blue video color signal outputs, with a twist rate of each said twisted pair communications line effecting a signal delay;
• a plurality of receivers, one of each for one of each said red, green and blue video color signal, each said receiver comprising:
• a balanced input coupled to said second end of a respective said communications line of said communications cable,
• an amplifier and balanced to single ended converter coupled to said balanced input, and
• a single-ended video signal color output couplable from said balanced to single-ended converter to a selected one of a plurality of monitors;
• said system also including a high frequency booster for each said video color signal.
