Specifically, the camera included in the image obtaining unit 120 is rotatable in the up, down, left, and right directions, and can rotate toward the determined remote control device. The image acquisition unit 120 may acquire an image of the remote controller through the rotated camera. The image acquisition unit 120 may transmit the acquired image to the controller 170. [

The image display device 100 displays an image of the obtained remote control device (S117).

The control unit 170 may display an image of the remote control device acquired by the image acquisition unit 120 on the display unit 180. [

In addition, the controller 170 can recognize the remote controller 200 from the acquired image. The control unit 170 can recognize the remote control device 200 by comparing the acquired image with the image of the remote control device 200 previously stored. When the control unit 170 displays an image of the remote control device, the recognized remote control device 200 can be displayed separately.

This will be described with reference to FIG.

11 shows an image display for a remote control device according to an embodiment of the present invention.

Referring to FIG. 11, the control unit 170 may display an image of the remote control device acquired by the image obtaining unit 120 on the display unit 180. The control unit 170 may display the remote control device 200 in a dotted line on the displayed image.

The description of the divisional display of the above-described remote control device is an example for explanation, and can be variously set according to the selection of the user or the designer.

The video display device 100 receives the remote control device search end signal (S119), and ends the remote control device search operation (S121).

The control unit 170 can receive the remote control device search end signal from the user or the remote control device 200. [ Then, the control unit 170 can terminate the remote control device searching operation of the video display device 100. Accordingly, the controller 170 can send out an alarm sound stop signal to cause the remote control device 200 to stop outputting the alarm sound. The control unit 170 may not display information on the position of the displayed remote control device.

In one embodiment, the voice acquiring unit 110 acquires a voice for the user's remote control device search end command, and can transmit the obtained remote control device search end command to the control unit 170.
