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.
Claims15
A display apparatus, comprising:
- a receiver that receives an image;
- a display that displays the image;
- a communicator that communicates with an external server and receives On-Screen Display (OSD) configuration information;
- and
- a controller that, when an OSD event occurs, extracts an OSD configuration element from the displayed image, and in response to determining that the extracted OSD configuration element matches the received OSD configuration information, obtains information regarding the displayed image from the extracted OSD configuration element.
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
- 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.
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.
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 that transmits OSD configuration information for a broadcast receiving apparatus, and in response to an image being received from the display apparatus, updates the OSD configuration information using the received image;
- and
- a display apparatus that, when an OSD event occurs, extracts an OSD configuration element from a displayed image;
- and
- in response to determining that the extracted OSD configuration element matches the received OSD configuration information, obtains 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, transmits the displayed image to the external server.
