Computer network having multiple remotely located human interfaces sharing a common computing system
First Claim
1. A computer network, comprising:
- a processor subsystem;
a plurality of nodes, each one of said plurality of nodes coupled to said processor subsystem and having a remotely located human interface comprised of a video monitor and an input/output ("I/O") device coupled thereto;
a transmission line;
each one of said plurality of nodes including a first interface device coupled to said processor subsystem and to said transmission line and each one of said human interfaces including a second interface device coupled to said video monitor, said I/O device and said transmission line;
a memory subsystem coupled to said processor subsystem, said memory subsystem including a plurality of memory areas, each corresponding to one of said plurality of nodes;
said processor subsystem using information stored in each one of said plurality of memory areas to appear, to said corresponding one of said plurality of nodes, as a dedicated processor for said human interface coupled to said node;
said first interface device comprising;
a video encoder coupled to said processor subsystem and said transmission line, said video encoder placing a stream of video information received from said processor subsystem onto said transmission line;
a first transceiver coupled to said processor subsystem and said transmission line, said first transceiver injecting a first set of data signals received from said processor subsystem into said stream of video information;
said second interface comprising;
a video decoder coupled to said transmission line to receive said stream of video information and to said video monitor; and
a second transceiver coupled to said transmission line and said I/O device, said second transceiver receiving said stream of video information in which said first set of data signals were injected and removing said first set of data signals from said stream of video information;
said second transceiver receiving a second set of data signals from said I/O device and injecting said second set of data signals into said stream of video information;
said first transceiver receiving said stream of video information in which said second set of data signals were injected and removing said second set of data signals from said stream of video.

Abstract
A computer network having multiple remotely located human interfaces which share a common computing system which appears, to each of the human interfaces, as a virtual computer dedicated to that human interface. The computer network includes a processor subsystem and a plurality of nodes, each coupled to the processor subsystem and having a remotely located human interface comprised of a video monitor and an I/O device coupled thereto. Each one of the nodes further incudes a first interface device coupled to the processor subsystem and to a transmission line while each of the human interfaces further includes a second interface device coupled to the video monitor, the I/O device and the transmission line. The computer network further includes a memory subsystem coupled to the processor subsystem and having a plurality of memory areas, each corresponding to one of the plurality of nodes. Using information stored in each one of the plurality of memory areas, the processor subsystem appears, to the corresponding one of the plurality of nodes, as a dedicated processor for the human interface coupled to the node.
