Abstract
A computer comprised of a computing system positioned at a first location and a human interface, which includes a video monitor, and plural I/O devices, specifically, a keyboard, mouse and printer, positioned at a second location remotely located relative to the first location. The computer further includes a first encoder coupled to the computer system, a first decoder coupled to the video monitor and the at least one I/O device and a transmission line which couples the encoder to the decoder. The first encoder receives, from the computing system, a video signal to be transmitted to the video monitor and a non-video signal to be transmitted to the at least one I/O device. The first encoder combines the video and the non-video signals into a combined signal and transmits the combined signal to the first decoder via the transmission line. The first decoder receives the combined signal, separates the video and non-video signals therefrom for respective propagation to the video monitor and the at least one I/O device.
