Method of linkage-viewing TV broadcasting program between mobile communication apparatus and digital TV, and mobile communication apparatus and digital TV thereof

A method of controlling a display apparatus, the method comprising:

• communicating with an external apparatus;
• receiving, from the external apparatus, information for linkage view to display a content which is being displayed in the external apparatus while the display apparatus operates in a state of power on, the information for linkage view being associated with information on the content and information on a predefined apparatus from which the content is received;
• and
• in response to the information for linkage view being received from the external apparatus, determining whether a predefined computer program for the linkage view is executed, and
• in response to determining that the predefined computer program is not executed, executing the predefined computer program so that the executed predefined computer program causes a display of a corresponding content based on the information on the content and the information on the predefined apparatus from which the content is received.

A display apparatus comprising:

• a display;
• a communicator configured to communicate with an external apparatus;
• and
• a controller configured:
• to receive, from the external apparatus, a signal requesting execution of a predefined computer program which is enabled to display a content which is being displayed in the external apparatus while the display apparatus operates in a state of power on, the signal being associated with information on the content and information on a predefined apparatus from which the content is received,
• in response to the signal being received from the external apparatus, to determine whether the predefined computer program is executed, and
• in response to determining that the predefined computer program is not executed, to control the predefined computer program to be executed so that the executed predefined computer program causes a display of a corresponding content based on the information on the content and the information on the predefined apparatus from which the content is received.

A display apparatus comprising:

• a display;
• a communicator configured to communicate with an external apparatus;
• and
• a controller configured:
• to receive, from the external apparatus, a command for displaying a content which is being displayed in the external apparatus while the display apparatus operates in a state of power on, the command being associated with information on the content,
• in response to the command being received from the external apparatus, to determine an operation state of a computer program which is related to the command, and
• in response to determining that the computer program is not executed, to control the computer program to be executed so that the executed computer program causes a display of a corresponding content based on the information on the content.
