Abstract

A display apparatus includes a receiver configured to receive an image, a display configured to display the image, a communicator configured to perform communication with an external server and receive On-Screen Display (OSD) configuration information, and a controller configured to, when an OSD event occurs, extract an OSD configuration element from the displayed image, determines whether the extracted OSD configuration element matches the received OSD configuration information, and in response to determining that the extracted OSD configuration element matches the received OSD configuration information, obtain information regarding the displayed image from the extracted OSD configuration element.

Claims

1. A display apparatus, comprising:

a receiver configured to receive an image;

a display configured to display the image;

a communicator configured to communicate with an external server and receive On-Screen Display (OSD) configuration information; and

a controller configured to, when an OSD event occurs, extract an OSD configuration element from the displayed image, determine whether the extracted OSD configuration element matches the received OSD configuration information, and in response to determining that the extracted OSD configuration element matches the received OSD configuration information, obtain information regarding the displayed image from the extracted OSD configuration element.

2. The display apparatus as claimed in claim 1, wherein the OSD configuration information includes at least one of location information, color information, brightness information, size information, and spacing information of the OSD configuration element,

wherein the OSD configuration element includes at least one of a channel number, a broadcast station name, a content title, and a current time.

3. The display apparatus as claimed in claim 1, wherein the controller is configured to, when an OSD event occurs, capture the displayed image for a predetermined time, and extract the OSD configuration element from one area of the captured image based on the received OSD configuration information.

4. The display apparatus as claimed in claim 3, wherein the controller is configured to, when there are a plurality of OSD configuration elements in the displayed image, determine whether the plurality of OSD configuration elements match the received OSD configuration information.

5. The display apparatus as claimed in claim 1, wherein the controller is configured to, when it is determined that the OSD configuration element does not exist in one area of the displayed image which is set based on the received OSD configuration information, or the extracted OSD configuration element does not match the received OSD configuration information, control the communicator to transmit the displayed image to the external server.

6. The display apparatus as claimed in claim 2, wherein the OSD configuration information corresponds to a broadcast receiving apparatus which provides an image displayed on the display apparatus.

7. The display apparatus as claimed in claim 1, wherein the controller is configured to recognize the extracted OSD configuration element as a letter, calculate a degree of recognition reliability, and in response to the calculated degree of recognition reliability being less than a predetermined threshold value, determine that the extracted OSD configuration element does not match the received OSD configuration information.

8. A method of controlling a display apparatus, comprising:

receiving On-Screen Display (OSD) configuration information from an external server;

when an OSD event occurs, extracting an OSD configuration element from the displayed image, and determining whether the extracted OSD configuration element matches the received OSD configuration information; and

in response to determining that the extracted OSD configuration element matches the received OSD configuration information, obtaining information regarding the displayed image from the extracted OSD configuration element.

9. The method as claimed claim 8, wherein the OSD configuration information includes at least one of location information, color information, brightness information, size information, and spacing information of the OSD configuration element, wherein the OSD configuration element includes at least one of a channel number, a broadcast station name, a content title, and a current time.

10. The method as claimed in claim 8, wherein the determining comprises, when an OSD event occurs, capturing the displayed image for a predetermined time;

and

extracting the OSD configuration element from one area of the captured image based on the received OSD configuration information, and determining whether the extracted OSD configuration element matches the received OSD configuration information.

12. The method as claimed in claim 8, further comprising:

when it is determined that the OSD configuration element does not exist in one area of the displayed image which is set based on the received OSD configuration information, or the extracted OSD configuration element does not match the received OSD configuration information, transmitting the displayed image to the external server.

13. The method as claimed in claim 9, wherein the OSD configuration information corresponds to a broadcast receiving apparatus which provides an image displayed on the display apparatus.

14. The method as claimed in claim 8, wherein the determining comprises:

recognizing the extracted OSD configuration element as a character and calculating a degree of recognition reliability,

wherein in response to the calculated degree of recognition reliability being less than a predetermined threshold value, it is determined that the extracted OSD configuration element does not match the received OSD configuration information.

11. The method as claimed in 10, wherein the determining comprises, when there are a plurality of OSD configuration elements in the displayed image, determining whether the plurality of OSD configuration elements match the received OSD configuration information.

15. A display system comprising:

a broadcast receiving apparatus transmitting an image and an On-Screen Display (OSD) including at least one of a channel number, a broadcast station name, and a content title to display apparatus;

an external server configured to transmit OSD configuration information for a broadcast receiving apparatus, and in response to an image being received from the display apparatus, update the OSD configuration information using the received image; and

a display apparatus configured to, when an OSD event occurs, extract an OSD configuration element from a displayed image, determine whether the extracted OSD configuration element matches the received OSD configuration information; and

in response to determining that the extracted OSD configuration element matches the received OSD configuration information, obtain information regarding the displayed image from the extracted OSD configuration element; and

in response to determining that the extracted OSD configuration element does not match the received OSD configuration information, transmit the displayed image to the external server.
