And if authentication is selected according to a user's operation, transmitting a wireless signal including at least one piece of authentication information to process the authentication at this time.
The wireless signal generation step,
And after the authentication is completed, including the authentication information in the wireless signal to be transmitted to the outside.
A binocular control step of controlling an on / off operation of each of the binoculars that gaze at the 3D image by performing synchronization based on the processed synchronization signal; And
A power saving mode step of stopping the radio signal reception function and generating a self synchronization signal based on the synchronization signal for a preset power saving mode time after performing the synchronization;
And controlling an on / off operation of each of the binoculars looking at the 3D image based on the self synchronization signal.
The power saving mode step,
After performing the synchronization, the power saving mode time is adjusted in response to the error time range between the self-synchronizing signal generated during the previously set power saving mode time and the sync signal processed this time, and the wireless signal receiving function is stopped during the adjusted power saving mode time. And generating a self synchronization signal based on the synchronization signal.
If a distortion occurs due to noise in the process of analyzing / processing a sync signal for a 3D image from the radio signal, requesting the sync controller to change a radio channel corresponding to the radio signal. Method of operation of the dedicated glasses device.
And if authentication is selected according to a user's operation, extracting and recording authentication information in a wireless signal received from the synchronous control device.
The radio signal processing step,
And selecting / processing a wireless signal corresponding to the recorded authentication information among wireless signals received from the outside after the authentication is completed.
If the wireless signal is not received from the synchronous control device when the power-off of the synchronous control device providing the wireless signal is recognized or a predetermined reception waiting time has elapsed, the power supply inside the device is turned on. -Off further comprising the step of operating a dedicated glasses device.
