Image display device and operating method for the same

A method of operating an image display apparatus, the method comprising:

• determining whether the image display apparatus is in a pre-set state in which the image display apparatus is controllable by a wheel key input, based on state information of a screen displayed on a display;
• in response to the image display apparatus being in the pre-set state, transmitting an activation signal to a control device;
• in response to the activation signal being transmitted, receiving a control signal corresponding to the wheel key input that is sensed by the control device;
• and
• in response to the control signal being received, controlling an operation of the image display apparatus, according to an interaction that is determined based on the control signal and the state information of the screen that is displayed on the display.

A non-transitory computer-readable storage medium storing instructions to cause a processor to:

• determine whether an image display apparatus is in a pre-set state in which the image display apparatus is controllable by a wheel key input, based on state information of a screen displayed on a display;
• in response to the image display apparatus being in the pre-set state, transmit an activation signal to a control device;
• in response to the activation signal being transmitted, receive a control signal corresponding to the wheel key input that is sensed by the control device;
• and
• in response to the control signal being received, control an operation of the image display apparatus, according to an interaction that is determined based on the control signal that is received and state information of the screen that is displayed on the display.
