Abstract: A remote controller includes a communicator and a processor configured to control the communicator to transmit an identification information request signal to a plurality of electronic apparatuses paired with the remote controller. Based on a signal that includes identification information being received from two or more of the plurality of electronic apparatuses in response to the identification information request signal, the processor controls the communicator to identify a direction of the remote controller based on a direction from which each of the signals is received. The processor causes communication to be performed via an exclusive communication channel between the remote controller and one of the plurality of electronic apparatuses based on the identified direction.

Abstract: A remote controller for controlling an external device by using voice recognition includes a microphone, at least one sensor, a communication interface, and a processor for controlling the microphone, the at least one sensor, and the communication interface, wherein the controller identifies a user utterance intention based on utterance intention information of the remote controller and utterance intention information of the external device, the utterance intention information of the remote controller being based on a state of the remote controller or an external state identified by the at least one sensor, and the utterance intention information of the external device being received from the external device through the communication interface, controls whether to supply power to the microphone according to a result of the identification of the user utterance intention, and controls the communication interface to transmit an electrical signal corresponding to a voice of user received through the microphone to

Abstract: An image display apparatus and a method of operating the same are provided. The image display apparatus includes a display configured to display a screen, and a communicator configured to communicate with a control device. The image display apparatus further includes a processor configured to control the communicator to transmit an activation signal to the control device, in response to the image display apparatus being in a pre-set state, control the communicator to receive a control signal corresponding to a wheel key input that is sensed by the control device in response to the activation signal being transmitted, and 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.

Abstract: A remote controller is provided, which includes a transmitter, a microphone configured to receive from a display device an audio signal including information on a code set capable of controlling an external device connected to the display device through a predetermined carrier frequency, a signal processor configured to convert the received audio signal, and a microcomputer configured to acquire the code set capable of controlling the external device from a converted signal if the received audio signal is converted into a form that can be processed through the signal processor, and to control the transmitter to transmit a control signal for controlling the external device on the basis of the code set.
