Abstract

The present invention may provide a display device that automatically configures a remote controller so that an external device connected to the display device can be controlled. According to the present display device, a power control code can be recognized on the basis of a response of a connected external device, and a control code set corresponding to the power control code can be received through a server. When there are a plurality of control code sets corresponding to the power control code, the corresponding control code sets can be received through the server by performing comparison with a user interface included in the video image received from the external device.

Claims14

Dependent claims

A display device capable of being connected to at least one external device, the display device comprising:

a memory for storing a power control code for controlling power of the at least one external device therein;
a tuner for receiving a broadcast signal;
a display module;
an external device interface to be wiredly or wirelessly connected to the at least one external device;
a network interface for performing bidirectional communication with a server storing a control code set for controlling the at least one external device;
a user input interface for performing bidirectional communication with a remote controller;
and
a controller for controlling the memory, the tuner, the display module, the external device interface, the network interface, and the user input interface,
wherein the controller is configured to:
transmit the power control code to the external device through the remote controller after the at least one external device is connected to the external device interface;
receive the control code set including the power control code from the server through the network interface when a signal received from the external device is blocked;
and
transmit the control code set to the remote controller.
