User terminal device, method for controlling user terminal device and multimedia system thereof

A multimedia system comprising:

• a display apparatus comprising:
• a display configured to display at least one first image contents;
• and
• a transceiver configured to transmit the first image contents;
• and
• a user terminal device comprising:
• a transceiver configured to receive the first image contents from the display apparatus;
• a display configured to display the first image contents received by the transceiver;
• a user interface configured to detect a user input on the display of the user terminal device;
• a controller configured to control the display of the user terminal device to display at least one second image contents having different number of image contents from the first image contents, in response to the user interface detecting the user input, wherein the transceiver is further configured to transmit to the display apparatus information identifying at least one image content of the second image contents to control the display apparatus to display the at least one image content of the second image contents on the display of the display apparatus.

A method for controlling an external display apparatus of a user terminal device, comprising:

• displaying on a display of the user terminal device at least one first image contents displayed on a display of the external display apparatus;
• detecting a user input on the display of the user terminal device;
• displaying at least one second image contents having different number of image contents from a number of the first image contents on the display of the user terminal device, in response to detecting the user input on the display of the user terminal device;
• and
• transmitting to the external display apparatus identification information identifying at least one image content of the second image contents to control the external display apparatus to display the at least one of the second image contents on the display of the external display apparatus.

A method for controlling a multimedia system comprising a display apparatus and a user terminal device, the method comprising:

• displaying at least one first image contents on a display of the display apparatus;
• transmitting the first image contents to the user terminal device;
• receiving the first image contents from the display apparatus at the user terminal device;
• displaying the first image contents on a display of the user terminal device;
• detecting a user input on the display of the user terminal device;
• displaying a second image contents having different number of image contents from a number of the first image contents on the display of the user terminal device;
• transmitting to the display apparatus identification information identifying at least one image content of the second image contents ;
• and
• displaying the at least one image content of the second image contents on the display of the display apparatus based on the identification information.

A portable terminal comprising:

• a display;
• a transceiver configured to receive a multiplexed stream of a plurality of image contents displayed on a display apparatus;
• a controller configured to control the display to display the plurality of image contents;
• a user interface configured to receive a user input configuring display of the plurality of image contents on the display,
• wherein the controller is further configured to control the transceiver to transmit to the display apparatus configuration information indicating configuration of the plurality of image contents on the display to control the display apparatus to display the configured plurality of image contents on the display apparatus.
