1. The method of exchanging unmodulated digital signals between digital signal apparatus, including computers, over a single conductor coaxial cable simultaneously with broadband transmission of RF modulated video signals between video signal apparatus over the same cable, the video apparatus including one or more video signal sources and one or more video signal receivers, the coaxial cable having a cable characteristic impedance, the method comprising:

  • establishing a plurality of signal frequency channels, including an RF video signal channel and a PC digital signal channel, each frequency channel having a different frequency range;

    connecting the signal input and output (I/O) ports of each digital signal apparatus to a first terminal of a digital signal frequency filter, a second terminal of which is connected to the coaxial cable, said digital signal frequency filter having a frequency passband which is substantially equal to the frequency range of said PC digital signal channel, said digital signal frequency filter providing a substantially equal filter characteristic impedance to unmodulated digital signals exchanged bi-directionally, at a signal bit speed, between said first terminal and said second terminal; and

    connecting each RF modulated video signal apparatus to the cable through an RF video signal frequency filter having a frequency passband which is substantially equal to the frequency range of said RF video signal channel, said RF video signal frequency filter providing a substantially equal filter characteristic impedance to RF modulated video signals propagating bi-directionally therethrough between the RF modulated video signal apparatus and the cable.
