Abstract

The present disclosure provides a display device comprising: a display unit for displaying a content; and a processor, wherein the processor is configured to: broadcast first channel information providing the content to at least one other display device if a mirroring operation of displaying the content on an external device is being performed; obtain hash data and a content ID associated with the content from the at least one other device; transmit the content ID and the hash data to a scene recognition information server; and obtain scene recognition information corresponding to the content via the scene recognition information server.

First claim

What is claimed is:

1 . A display device comprising:
a display configured to display content; and a processor configured to: perform a mirroring operation by causing display of the content on an external device; determine whether a content recognition function is operable, or is not operable, at the display device; turn on power of at least one other display device, based on no other display device among the at least one other display device, is powered on; broadcast first channel information associated with the content to the at least one other display device that is connected through a sync channel of a hub device, based on the content recognition function being not operable at the display device; obtain hash data and a content ID associated with the content from the at least one other display device, based on the first channel information; transmit the hash data and the content ID to a scene recognition information server; and obtain, from the scene recognition information server, scene recognition information that corresponds to the content.

2 . The display device of claim 1 , wherein the processor is configured to display the scene recognition information on the display of the display device.

3 . The display device of claim 2 , wherein the processor is configured to perform an operation of mirroring, to the external device, a captured image obtained by capturing the content displayed on the display of the display device along with the scene recognition information.

4 . The display device of claim 1 , wherein the processor is configured to:
obtain second channel information broadcast from the at least one other display device; when the content recognition function is operable at the display device, determine whether content displayed on the at least one other display device is a same content as the content displayed on the display device, based on the second channel information; and when the same content is being displayed, broadcast a content ID and hash data for the same content.

5 . The display device of claim 4 , wherein the processor is configured to:
generate a captured image by capturing at least one scene of the same content; generate a capture hash for the captured image; transmit the capture hash to a content information server; obtain a second content ID corresponding to the capture hash from the content information server; and broadcast the second content ID and the captured hash for the captured image.

6 . The display device of claim 4 , wherein the processor is configured to:
when the content displayed on the at least one other display device is different from the content displayed on the display of the display device, terminate the displaying of the content on the at least one other display device for a predetermined time, and display the same content on the at least one other display device for a predetermined time, based on the second channel information.

7 . The display device of claim 1 , wherein the processor is configured to:
receive a request for continuous viewing from the at least one other display device; receive channel information, a second content ID, and second hash data associated with content displayed on the at least one other display device; and perform scene recognition based on the channel information, the second content ID, and the second hash data.

8 . The display device of claim 7 , wherein the processor is configured to turn on power of the display device upon receiving the request for continuous viewing when the power of the display device is turned off before receiving the request for continuous viewing.

9 . The display device of claim 8 , wherein the processor is configured to, when the power of the display device is turned on, initialize a program associated with the content recognition function and establish a connection with a content information server.

10 . A scene recognition method comprising:
displaying content; performing a mirroring operation of displaying the content on an external device; determining whether a content recognition function is operable, or is not operable; turning on power of at least one other display device, based on no other display device among the at least one other display device, is powered on; broadcasting first channel information associated with the content to the at least one other display device that is connected through a sync channel of a hub device, based on the content recognition function being not operable at the display device; obtaining hash data and a content ID associated with the content from the at least one other display device, based on the first channel information; transmitting the hash data and the content ID to a scene recognition information server; and obtaining, from the scene recognition information server, scene recognition information that corresponds to the content.

11 . The scene recognition method of claim 10 , further comprising displaying the scene recognition information.

12 . The scene recognition method of claim 11 , further comprising:
capturing the displayed content along with the displayed scene recognition information to obtain a captured image; and performing an operation of mirroring the captured image to the external device.

13 . A scene recognition method performed by a display device, the scene recognition method comprising:
turning on power of at least one other display device, based on no other display device among the at least one other display device, is powered on; obtaining channel information broadcast from the at least one other display device; connecting through a sync channel of a hub device; determining whether a content recognition function is operable, or is not operable, at the display device; when the content recognition function is operable, determining whether content displayed on the at least one other display device is a same content as content displayed on the display device, based on the channel information; and when the same content is being displayed, broadcasting a content ID and hash data for the same content to a content information server.

14 . The scene recognition method of claim 13 , wherein the broadcasting of the content ID and the hash data for the same content comprises:
generating a captured image obtained by capturing at least one scene of the same content; generating a capture hash for the captured image; transmitting the capture hash to the content information server; and obtaining a content ID corresponding to the capture hash from the content information server.

15 . The scene recognition method of claim 13 , further comprising when the content displayed on the at least one other display device is different from the content displayed on the display of the display device, terminate the displaying of the content on the at least one other display device for a predetermined time, and displaying the same content on the at least one other display device for the predetermined time, based on the channel information.
