Abstract

Provided are a video display device and a method of operating the same. The method includes: executing an enhanced service playing application not dependent on any single channel; obtaining an uncompressed audio video (AV) content; playing the uncompressed AV content through the display unit; attempting to obtain contents information on the uncompressed AV content on the basis of a part of the uncompressed AV content; transmitting an enhanced service request message to an enhanced service providing server not dependent on any single channel by the enhanced service; receiving an enhanced service from the enhanced service providing server; and playing the enhanced service through the display unit by the enhanced service playing application.

Claims

1. A video display device comprising:

a tuner configured to receive a broadcasting signal;

a receiver configured to receive an uncompressed audio or video (AV) content; and

an enhanced service manager circuit configured to extract characteristic information from a part of the uncompressed AV content, wherein the characteristic information includes at least one of a watermark and a fingerprint, transmit a first query to a first server, wherein the first query corresponds to the characteristic information, receive a first response corresponding to the first query from the first server, transmit a second query to a second server based on the first response, receive a second response corresponding to the second query from the second server, receive an application, for outputting an enhanced service, based on the second response, and execute the application based on the second response,

wherein the first response includes a timestamp of the part of the uncompressed AV content and an address of the second server, and

the second response includes an address of the application, request period for the application and information on an acquisition path of the application.

2. The video display device according to claim 1, wherein the enhanced service manager circuit outputs a menu for selecting the enhanced service through the application for recommending.

3. The video display device according to claim 2, wherein the menu comprises a program menu for outputting information on the uncompressed AV content,

wherein the enhanced service manager circuit outputs a content metadata and a replay service of the uncompressed AV content, when the program menu is selected.

4. The video display device according to claim 2, wherein the menu comprises a recommending menu for recommending related to the uncompressed AV content, and

wherein the enhanced service manager circuit outputs a recommending content or a recommending application which is related to at least one of a title, a genre and an actor of the uncompressed AV content, when the recommend menu is selected.

5. The video display device according to claim 4, wherein the enhanced service manager circuit obtains a user characteristic which represents a preference of a user, and outputs the recommending content and the recommending application based on the user characteristic, and

wherein the user characteristic includes at least one of a user basic profile, a major watching genre, a major watching program, a broadcast watching time slot and a keyword which is inputted by the user.

6. The video display device according to claim 5, wherein the enhanced service manager circuit obtains information on a group of the user who watched the uncompressed AV content, based on the user characteristic and outputs the recommending content and the recommending application based on the group.

7. The video display device according to claim 2, wherein the menu comprises a talk menu for outputting an online article related to the uncompressed AV content, and

wherein the enhanced service manager circuit outputs a SNS (Social Network Service) article which is related to at least one of a title, a genre and an actor of the uncompressed AV content, when the talk menu is selected.

8. The video display device according to claim 2, wherein the menu comprises a plus menu for representing an enhanced data related the uncompressed content, and

wherein the enhanced service manager circuit outputs information on a goods or a place which is related to the uncompressed AV content.

9. The video display device according to claim 1, wherein the enhanced service manager circuit receives audience rating information from the second server and outputs the audience rating information.
