摘要： Disclosed herein are a 3D TV and a system using RF wireless communication and a method for synchronizing a 3D TV system using the same. In the 3D TV system using the RF wireless communication according to an exemplary embodiment of the present invention, two or more 3D TVs transmit and receive synchronous signals through the RF wireless communication, thereby locking the screen synchronization and synchronous signals of the 3D TVs. Thereafter, when the 3D TVs transmits the synchronous signals to the 3D spectacles, the synchronous signals including the time offset are transmitted, having different time difference. As a result, the 3D spectacles can be synchronized with images displayed on the 3D TVs by using time offset information.

摘要： An apparatus and a system for viewing a 3D image including a synchronization signal receiver for receiving 3D image synchronization signal; a 3D control signal generator for generating left-eye glass control signal and a right-eye glass control signal in accordance with the synchronization signal received; a left-eye glass that opens or intercepts light transmitted to the left-eye glass; a right-eye glass that opens or intercepts light transmitted to the right-eye glass; a central processor that controls operation of the 3D control signal generator and transmits the synchronization signal to the 3D control signal generator; and a power controller that connects or intercepts power supplied to the synchronization signal receiver and the central processor. The power consumption of the apparatus is minimized by supplying power to the synchronization signal receiver and the central processor at a time when the synchronization signal is received and power is intercepted during the rest period.
