Display system and method of controlling the same
First Claim
1. A method of controlling a display system, the method comprising:
- receiving video signals from a plurality of video sources through a video input unit of the display system; and
controlling the display system according to a central control signal when a central control unit is operatively connected to a central control input unit of the display system that is separate from a local control input unit, the central control signal being generated by the central control unit, wherein the controlling step comprises;
receiving the central control signal through the central control input unit;
selecting a video signal from one of the plurality of video sources based on the received central control signal.

Abstract
A display system includes a video input unit that receives video signals from one or more video sources, a control input unit, and a microprocessor. The microprocessor generates a switch signal according to a central control signal if a central control unit is determined to be operatively connected to the control input, where the central control signal is generated by the central control unit and is received through the control input unit. Then a switch included in the display system selects one of the received video signals according to and upon receiving the first switch signal. A display unit, which is further included in the display system, then displays the selected video signal according to the central control signal.
