Abstract

Disclosed are a method and apparatus of processing input signals of a display appliance having a plurality of external input terminals and connected to a set top box with a plurality of external input terminals. The method comprises the steps of: detecting a connecting state to the set top box, a signal receiving state from the set top box, a signal receiving state via the external input terminals of the display appliance; selecting and outputting any one of signals supplied from the set top box and signals supplied via external input terminals of the display appliance; and during outputting the selected signal, if a user requests to output a signal inputted from any one of external input terminals of the set top box and the display appliance, selecting and outputting the selected signal.

Claims

1. A method of processing input signals of a display appliance having a plurality of external input terminals and connected to a set top box with a plurality of external input terminals, the method comprising the steps of:

a) detecting a connecting state to the set top box, a signal receiving state from the set top box, a signal receiving state via the external input terminals of the display appliance;

b) selecting and outputting any one of signals supplied from the set top box and signals supplied via external input terminals of the display appliance; and

c) during outputting the selected signal, if a user requests to output a signal inputted from any one of external input terminals of the set top box and the display appliance, selecting and outputting the selected signal.

2. The method in claim 1, wherein the step b) comprises the steps of:

if the signal is inputted from the set top box only, selecting and outputting the signal inputted from the set top box;

if the signal is not inputted from the set top box and the signals are inputted from the input terminals of the display appliance only, selecting and outputting any one of the signals; and

if the signals are inputted from the set top box and the input terminals of the display appliance, selecting and outputting the signal inputted from the set top box.

3. The method in claim 1, further comprising a step of displaying an input mode corresponding to the selected signal, whenever the signal is selected and outputted.

4. An apparatus of processing input signals of a display appliance having a plurality of external input terminals and connected to a set top box with a plurality of external input terminals, the apparatus comprising:

an AV switch for selecting and outputting any one of signals inputted from the set top box and the external input terminals of the display appliance;

a video/image processor for processing the signal selected and outputted by the AV switch to convert a signal which is able to be outputted;

a display for receiving an output of the video/image processor to display the output;

an operating unit for providing a user with an interface; and

a micro computer for, after a connecting state to the set top box and a signal receiving state from the set top box are detected, selecting and outputting any one of signals supplied from the set top box and signals supplied via external input terminals of the display appliance, and during outputting the selected signal, if a user requests to output a signal inputted from any one of external input terminals of the set top box and the display appliance, controlling the set top box, the AV switch and the video/image processor to output the selected signal.

5. The apparatus in claim 4, wherein the micro computer controls:

if the signal is inputted from the set top box only, selecting and outputting the signal inputted from the set top box;

if the signal is not inputted from the set top box and the signals are inputted from the input terminals of the display appliance only, selecting and outputting any one of the signals; and

if the signals are inputted from the set top box and the input terminals of the display appliance, controlling the set top box, the AV switch and the video/image processor to select and output the signal inputted from the set top box.

6. The apparatus in claim 4, wherein the micro computer controls the image processor to display an input mode of the inputted signal through an on-screen display, whenever the signal is selected and outputted.
