System and method for using a shared bus for video communications
First Claim
1. A computer system, comprising:
- a mid-plane including a video bus;
at least one server module including a video output module in communication with the video bus, the video output module operable to transmit a video signal over the video bus and to receive control signals from the video bus; and
a management module in communication with the video bus, the management module operable to receive the video signal from each server module via the video bus and to provide the control signals through the video bus to each server module to activate and deactivate the video output module on each server module.

Abstract
A system and method for using a shared bus to control a keyboard, video, and mouse (KVM) output is disclosed. The system may include a mid-plane having a video bus. At least one server module, including a video output module, may be placed in communications with the video bus. The video output module may transmit a video signal over the bus and receives a control signal over the bus. A management module may also be placed in communications with the video bus. The management module may receive the video signal from the server module via the bus and provide a control signal through the video bus to each server module. The control signal may activate or deactivate the video output module on each server module.

10. An information handling system, comprising:
-
a server module communicatively coupled to a bus;
a unique address associated with the server module based on a location of the server module in the information handling system, the unique address operable to identify the server module;
a video output module in the server module, the video output module operable to transmit video signals to the bus; and
a controller switch in the server module, the controller switch operable to receive control signals from the bus and enable and disable transmission of video signals from the video output module in response to the control signals. - View Dependent Claims (11, 12)
