Abstract: A display apparatus, a broadcast signal receiving apparatus and methods thereof are provided. The display apparatus includes a signal receiver configured to receive data of content, a display configured to display an image, an interface comprising interface circuitry configured to communicate with a security processing module, and a processor configured to transmit first data of the content to the security processing module in response to a recording event of the content, to receive and store second data and information of a security identifier of the content from the security processing module, and to display an image of the content to which the security identifier is added based on the stored second data and information in response to a play-back event to the content. Accordingly, if the content is recorded and then played back, the security identifier may be displayed in the played-back image of the content, thereby protecting the played-back content enough to prevent and/or reduce unauthorized use thereto.

Abstract: A display apparatus includes a signal receiver configured to receive a broadcast signal comprising a broadcast content and channel information and corresponding to a plurality of channels, a signal processor configured to process the received broadcast signal and extract the broadcast content and the channel information from the broadcast signal, a display configured to display an image based on the extracted broadcast content, and a controller configured to determine a plurality of overlapped channels, which have the same broadcast content but are different in a type of broadcast content, based on the extracted channel information, and perform a control operation for the determined overlapped channels. A method of controlling the display apparatus includes determining a plurality of overlapped channels, which have the same broadcast content but are different in a type of broadcast content, based on the extracted channel information, and performing a control operation for the determined overlapped channels.
