1. A computer, comprising:

  • a computing system located at a first location;

    a human interface located at a second location, said second location remotely located relative to said first location, said human interface comprised of a video monitor and first, second and third I/ O devices;

    a first encoder coupled to said computing system;

    a second encoder, coupled to said computing system and said first encoder, said second encoder receiving a first non-video signal to be transmitted to said first I/O device, a second non-video signal to be transmitted to said second I/O device and a third non-video signal to be transmitted to said third I/O device and combining said first, second and third non-video signals into a non-video signal received by said first encoder;

    said first encoder receiving a video signal to be transmitted to said video monitor and receiving the non-video signal from the second decoder and combining said video and said non-video signals into a first combined signal;

    a first decoder coupled to said video monitor and said at least one I/O device;

    said first decoder receiving said first combined signal from said first encoder and separating said video and non-video signals therefrom for respective propagation to said video monitor and said at least one I/O device;

    a second decoder, coupled to said first decoder and said first, second and third I/O devices, said second decoder receiving said non-video signal from said first decoder;

    separating said first, second and third non-video signals therefrom and transmitting said first, second and third non-video signals to said first, second and third I/O devices, respectively; and

    a transmission line coupling said first encoder and said first decoder.
