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.

Claims

1. A remote controller, comprising:

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 via a predetermined carrier frequency;

a signal processor configured to convert a received audio signal; and

a microcomputer configured to acquire the code set capable of controlling the external device from a converted signal when the received audio signal is converted into a form that can be processed via the signal processor, and to control the transmitter to transmit a control signal for controlling the external device on a basis of the code set.

2. The remote controller as claimed in claim 1, wherein the signal converts the received audio signal into a TTL (Transistor-Transistor Logic) signal that can be processed by the microcomputer by amplifying the predetermined carrier frequency band of the received audio signal and passing a frequency band that is lower than a predetermined frequency band of an amplified audio signal.

3. The remote controller as claimed in claim 1, wherein the microcomputer acquires from the converted signal the code set including a custom code that corresponds to the external device and a key code for controlling an operation of the external device.

4. The remote controller as claimed in claim 3, wherein the microcomputer determines a key code that corresponds to a selected button on a basis of the code set when one of a plurality of buttons provided on the remote controller is selected, and controls the transmitter to generate and transmit to the external device an IR control signal including the custom code and the determined key code.

5. The remote controller as claimed in claim 1, wherein the predetermined carrier frequency comprises a carrier frequency of 18 kHz.

12. The remote controller as claim in claim 1, wherein the remote controller does not store a code set capable of controlling the external device connected to the display device.

6. A method for controlling a remote controller, comprising:

receiving from a display device an audio signal including information on a code set capable of controlling an external device connected to the display device via a predetermined carrier frequency;

converting a received audio signal; and

acquiring the code set capable of controlling the external device from a converted signal when the received audio signal is converted into a form that can be processed, and transmitting a control signal for controlling the external device on a basis of the code set.

7. The method as claimed in claim 6, wherein the converting the received audio signal comprises converting the received audio signal into a TTL (Transistor-Transistor Logic) signal by amplifying a predetermined carrier frequency band of the received audio signal and passing a frequency band that is lower than the predetermined frequency band of the amplified audio signal.

8. The method as claimed in claim 6, wherein the acquiring the information on the code set capable of controlling the external device comprises acquiring from the converted signal the code set including a custom code that corresponds to the external device and a key code for controlling an operation of the external device.

9. The method as claimed in claim 8, wherein the transmitting the control signal comprises determining a key code that corresponds to a selected button on a basis of the code set when one of a plurality of buttons provided on the remote controller is selected, and generating and transmitting to the external device an IR control signal including the custom code and the determined key code.

10. The method as claimed in claim 6, wherein the predetermined carrier frequency comprises a carrier frequency of 18 kHz.

11. A non-transitory computer readable storage medium storing a method as claimed in claim 6.

13. The method as claimed in claim 6, wherein the remote controller does not store a code set capable of controlling the external device connected to the display device.
