The electronic device 510 transmits a second RF signal indicating the generated identification information 515 to the glasses 520. The glasses 520 store identification information 515 notified by the transmitted second RF signal. That is, the identification information 525 of the glasses 520 becomes the identification information 515.

The remote controller 530 transmits a third RF signal for requesting pairing to the electronic device 510. The electronic device 510 changes a part of the stored identification information 515 in response to receiving the third RF signal, and stores the changed identification information 535. The electronic device 510 transmits a fourth RF signal indicating the changed identification information 535 to the remote controller 530. The remote controller 530 stores identification information 535 notified by the transmitted fourth RF signal. Herein, the changed part of the identification information may be a variable part.

Next, a case in which process S1 is performed after process S2 is performed will be described. The remote controller 530 transmits a first RF signal for requesting pairing to the electronic device 510. The electronic device 510 generates identification information 535 in response to receiving the first RF signal, and stores the generated identification information 535. The electronic device 510 transmits a second RF signal indicating the generated identification information 535 to the remote controller 530. The remote controller 530 stores the identification information 535 included in the transmitted second RF signal.

The glasses 520 transmit a third RF signal for requesting pairing to the electronic device 510. The electronic device 510 reads the stored identification information 535 in response to the third RF signal, and transmits a fourth RF signal indicating the read identification information 535 to the glasses 520. The glasses 520 store identification information 535 notified by the transmitted fourth RF signal. That is, the identification information 515 of the electronic device and the identification information 525 of the glasses become identification information 535.

In the case where process S1 and process S2 are performed and identification information is stored in the electronic device 510, the glasses 520, and the remote controller 530, when S2 is further performed, process S2 is performed after process S1 is performed. It may proceed in a manner corresponding to the case. In addition, in the case where process S1 and process S2 are performed so that identification information is stored in the electronic device 510, the glasses 520, and the remote controller 530, when S1 is further performed, process S1 is performed after process S2 is performed. If so, it may proceed in a corresponding manner.

Since the present invention performs pairing by changing a part of the generated identification information, the pairing information of the electronic device and the RF glasses is not changed when the RF remote control is changed or re-paired when the RF glasses and the RF remote control are used at the same time. Therefore, there is no need to perform additional pairing for RF communication between the electronic device and the glasses, thereby reducing user inconvenience.
