Control device and method for control of broadcast receiver

A display system comprising:

• a display apparatus;
• and
• a control device for use with the display apparatus,
• wherein the control device comprises:
• a user interface configured to receive a user input for controlling the display apparatus;
• a bi-directional communication interface;
• a uni-directional communication interface;
• and
• a controller configured to:
• receive the user input via the user interface while the bi-directional communication interface is in an active state,
• in response to the user input via the user interface being identified as a first user input, control the control device to transmit a first signal corresponding to the first user input to the display apparatus via the bi-directional communication interface, and
• in response to the user input via the user interface being identified as a second user input different from the first user input, control the control device to transmit a second signal corresponding to the second user input to the display apparatus via the uni-directional communication interface instead of the bi-directional communication interface,
• wherein the control device further comprises a display, and
• wherein the controller is further configured to:
• display a user interface (UI) for receiving a user input to change a uni-directional communication mode to a bi-directional communication mode.

A control device for use with a display apparatus, the control device comprising:

• a user interface configured to receive a user input for controlling the display apparatus;
• a bi-directional communication interface configured to transmit a first signal to the display apparatus using a bi-directional communication;
• a uni-directional communication interface configured to transmit a second signal to the display apparatus using a uni-directional communication;
• and
• one or more controllers configured to:
• in response to receiving a first user input via the user interface while the bi-directional communication between the display apparatus and the control device is in an active state, control the control device to transmit the first signal corresponding to the first user input to the display apparatus using the bi-directional communication, and
• in response to receiving a second user input different from the first user input via the user interface while the bi-directional communication between the display apparatus and the control device is in the active state, control the control device to transmit the second signal corresponding to the second user input to the display apparatus using the uni-directional communication instead of the bi-directional communication.
