DC CAFCFirst Claim
1. A signal switch for sharing a video monitor, a plurality of console devices, each having a mouse and a keyboard, compliant with an industry standard and one or more than one peripheral device in any of a plurality of computer systems, comprising:
- a CPU for managing the signal switch;
a hub switch module connected to the CPU and configured to communicate with any of the plurality of computer systems, and the one or more than one peripheral device, such that a signal passing from the hub switch module to the one or more than one peripheral device emulates origination from one of the plurality of computer system;
a device control module for emulating the console devices according to the industry standard, connected to the CPU and the hub switch module;
a host control module connected to the CPU and configured to communicate with the plurality of console devices; and
a video control module connected to the CPU and configured to communicate with the video monitor;
wherein control of the one or more than one peripheral device can be maintained by one of the plurality of computer systems even while the video monitor, the keyboard and the mouse are controlling another one of the plurality of computer systems.
