Broadcast receiving apparatus, method of controlling the same, user terminal device, and method of providing screen thereof

A terminal device comprising:

• a storage which stores a program for executing a function;
• a communicator configured to establish a communication connection by searching for an apparatus when the program is executed, and receives a video frame to which a GUI is added from the apparatus;
• a decoder configured to decode the video frame to which the GUI is added;
• a display unit which displays the video frame to which the GUI is added;
• a sensor configured to sense a touch operation on the display unit;
• and
• a controller configured to transmit a coordinate value of a touch point to the apparatus when the touch operation is sensed and control an operation of the apparatus.

A method of controlling an apparatus, comprising:

• receiving a signal;
• generating a video frame by processing the signal and adding a GUI to the generated video frame;
• displaying the video frame to which the GUI is added;
• transmitting the video frame to which the GUI is added to a terminal device that executes a function when a communication connection with the user terminal device is established;
• and
• determining whether the GUI has been selected according to a touch coordinate value when the video frame is touched on the terminal device and the touch coordinate value is transmitted, and performing an operation corresponding to a determination result.

A method of providing a screen of a terminal device, comprising:

• establishing a communication connection by searching for an apparatus when a function is executed;
• receiving a video frame to which a GUI is added from the apparatus;
• decoding the video frame to which the GUI is added;
• displaying the video frame to which the GUI is added;
• sensing a touch operation on the video frame;
• and
• transmitting a coordinate value of a touch point to the apparatus when the touch operation is sensed and controlling an operation of the apparatus.
