Abstract
The present invention provides an intelligent, modular multimedia computer management system for coupling a series of remote computers to one or more user workstations to allow each user workstation to selectively access and control one or more remote computers. The computer management system incorporates a centralized switching system that receives keyboard, cursor control device, audio, and auxiliary peripheral device signals from the user workstation and transmits and applies the signals to the remote computer in the same manner as if the keyboard, cursor control device, audio input source, or auxiliary peripheral device of the user workstation were directly coupled to the remote computer. Also, the user workstation receives audio signals and auxiliary peripheral device signals from the remote computer. In addition, the multimedia computer management system transmits video signals from the remote computer over an extended range for display on the video monitor of the user workstation.
