Display device and method for recommending content using same

1 . A display device comprising:

a display configured to display first content;

a processor configured to perform a mirroring operation of displaying the first content on an external device; and

a communication interface configured to receive device identification information of the external device from the external device,

wherein the processor generates first content playback information of the first content and transmits the device identification information of the external device and the first content playback information to a content server through the communication interface, and

wherein the processor generates a first content setting information based on image quality information set by a user when the first content is mirrored to the external device,

wherein the first content setting information is generated based on a mirroring start time when mirroring to the external device started, a mirroring end time when mirroring to the external device ended, and a total mirroring time during which the first content was mirrored to the external device,

wherein the processor transmits the first content setting information to the content server in association with the device identification information of the external device for storage, and

wherein when re-mirroring content to a same external device, the processor receives the stored first content setting information from the content server and automatically controls image quality of the re-mirrored content based on the stored first content setting information without requiring user input.

2 . The display device of claim 1 , wherein the first content playback information comprises at least one of content identification information which is identification information of the first content or content genre information which is genre information of the first content.

3 . The display device of claim 2 , wherein the first content playback information comprises at least one of content playback start time information which is information on a time when the mirroring started, content playback end time information which is information on a time when the mirroring ended or total content playback time information which is information on a total time when the mirroring was performed.

4 . The display device of claim 1 ,

wherein the processor obtains a content change command for changing the first content to second content, changes the first content to the second content in response to the content change command and performs a mirroring operation of displaying the second content on the external device.

5 . The display device of claim 4 , wherein the processor generates second content playback information or second content setting information of the second content and transmits at least one of the device identification information of the external device, the second content playback information or the second content setting information to the content server.

6 . The display device of claim 4 , wherein the processor obtains the content change command from the external device through the communication interface.

7 . The display device of claim 1 , wherein the processor transmits the device identification information of the external device and a content recommendation request to the content server through the communication interface.

8 . The display device of claim 7 , wherein the processor receives a recommendation content list recommended based on the device identification information of the external device from the content server through the communication interface and displays the recommendation content list to mirror the list to the external device.

9 . The display device of claim 1 , wherein the processor sets a volume of the first content based on volume setting information included in the content setting information to mirror the first content to the external device.

10 . A content recommendation method performed by a display device, the content recommendation method comprising:

displaying first content;

performing a mirroring operation of displaying the first content on an external device;

receiving device identification information of the external device from the external device;

generating first content playback information of the first content; and

transmitting the device identification information of the external device and the first content playback information to a content server, and

wherein the performing a mirroring operation of displaying the first content on an external device comprises:

generating a first content setting information based on image quality information set by a user when the first content is mirrored to the external device,

wherein the first content setting information is generated based on a mirroring start time when mirroring to the external device started, a mirroring end time when mirroring to the external device ended, and a total mirroring time during which the first content was mirrored to the external device,

transmitting the first content setting information to the content server in association with the device identification information of the external device for storage, and

when re-mirroring content to a same external device, receiving the stored first content setting information from the content server and automatically controlling image quality of the re-mirrored content based on the stored first content setting information without requiring user input.

11 . The content recommendation method of claim 10 , further comprising:

obtaining a content change command for changing the first content to second content;

changing the first content to the second content in response to the content change command;

performing a mirroring operation of displaying the second content on the external device;

generating second content playback information or second content setting information of the second content; and

transmitting at least one of the device identification information of the external device, the second content playback information or the second content setting information to the content server.

12 . The content recommendation method of claim 10 , further comprising:

transmitting the device identification information and a content recommendation request to the content server;

receiving a recommendation content list recommended based on the device identification information from the content server; and

performing a mirroring operation of displaying the recommendation content on the external device.
