1. A display system receiving a video signal from a computer and displaying a picture on a screen corresponding to the video signal, comprising:
- an input terminal;
a signal processor converting an input signal applied to the input terminal into an output signal to be recognized by the computer;
a data interface coupled to the signal processor and connected between the computer and the display system; and
a controller transmitting the output signal to the computer via the signal processor and the data interface and generating an activation control signal to the input terminal and an output terminal when the input signal represents an activation signal to initiate an increase in consumption of energy by an external apparatus coupled to the input and output terminal.

Abstract
Disclosed is a display system displaying a picture on a screen by a video signal from a computer and serving as an input device of a computer coupled to the display system. The display system includes an input part through which a user inputs data, a signal processing part converting a signal inputted from the input part into a signal to be identified by the computer, a data interface between the computer and the display system, and a controlling part transmitting the signal inputted from the input part to the computer via the signal processing part and the data interface.

16. Controlling a display device, with the steps comprised of:
-
receiving an input signal from a mouse or a keyboard at an input terminal of the display device; receiving a video signal and transmitting an output signal via an input and output (I/O) connector disposed within the display device; alternatively selecting one of a first mode and a second mode; converting the input signal into a converted signal to be identified by a computer when the first mode is selected; transmitting the converted signal via the I/O connector to the computer for analysis; controlling a display of the display device in response to the input signal when the second mode is selected; making a determination of whether the input signal is a shut-down signal or an activation signal for activating an external apparatus coupled to the I/O connector; and applying a control signal to the I/O connector to regulate energy consumption by an appliance coupled to the I/O connector in dependence upon the determination. - View Dependent Claims (17)
