Display device

1 . A display device, comprising:

a display;

an external device interface configured to provide a connection path with an external device;

a memory configured to match and store device information and setting information for integrated remote control setting; and

a controller configured to:

acquire information about the external device,

if device information identical to the acquired information is stored in the memory, perform integrated remote control setting for the external device using setting information matched with the stored device information, and

if device information identical to the acquired information is not stored in the memory, display a screen for integrated remote control setting on the display,

wherein the device information stored in the memory includes a feature frame received from a server, and

the controller is configured to:

acquire a video frame based on a video signal received from the external device, and

if the feature frame matching the acquired video frame is stored in the memory, perform the integrated remote control setting using the setting information matching the feature frame.

2 . The display device of claim 1 , wherein the information about the external device includes HDMI (High Definition Multimedia Interface) SPD (Source Product Description) information and HDMI CEC (Consumer Electronic Control) information received through the external device interface.

3 . The display device of claim 2 , wherein the controller is configured to, if the device information identical to the information about the external device including the HDMI SPD information and the HDMI CEC information is stored in the memory, read-out setting information matching the stored device information and perform the integrated remote control setting using the read-out setting information.

4 . The display device of claim 1 , further comprising a network interface for network connection with the server, and

the controller is configured to receive the feature frame from the server through the network interface when manually setting the integrated remote control for the external device.

5 . The display device of claim 1 , wherein the controller is configured to:

capture a video based on a video signal received from the external device after the external device is disconnected and reconnected, and

if an image matching the captured video is stored in the memory, perform the integrated remote control setting using the setting information matching the stored video.

6 . The display device of claim 5 , wherein the captured video is one of a home screen video provided by the external device and a channel video displayed when channel is changed.

7 . The display device of claim 1 , wherein the setting information includes a brand name of the external device, a type of the external device, and a code set of a remote control.

8 . An operating method of a display device, comprising:

acquiring information about an external device;

if device information identical to the acquired information is stored in a memory of the display device, performing integrated remote control setting for the external device using setting information matching the stored device information; and

if device information identical to the acquired information is not stored in the memory, displaying a screen for the integrated remote control setting,

wherein the device information stored in memory includes a feature frame received from a server, and

the performing of the integrated remote control setting includes:

acquiring a video frame based on a video signal received from the external device, and

performing the integrated remote control setting using setting information matching the feature frame when the feature frame matching the acquired video frame is stored in the memory.

9 . The operating method of a display device of claim 8 , wherein the information about the external device includes HDMI (High Definition Multimedia Interface) SPD (Source Product Description) information and HDMI CEC (Consumer Electronic Control) information received through the external device interface.

10 . The operating method of a display device of claim 9 , wherein the performing of the integrated remote control setting includes:

reading out setting information matching the stored device information if the device information identical to the information about the external device including the HDMI SPD information and the HDMI CEC information is stored in the memory, and

performing the integrated remote control setting using the read-out setting information.

11 . The operating method of a display device of claim 9 , further comprising receiving the feature frame from the server when manually setting the integrated remote control for the external device.

12 . The operating method of a display device of claim 8 , wherein the performing of the integrated remote control setting includes:

capturing a video based on a video signal received from the external device when the external device is reconnected after the external device is disconnected, and

performing the integrated remote control setting using setting information matching the stored video when a video matching the captured video is stored in the memory.

13 . The operating method of a display device of claim 12 , wherein the captured video is one of a home screen video provided by the external device and a channel video displayed when channel is changed.
