METHOD AND APPARATUS FOR RECEIVING SYNC SIGNAL AND METHOD AND APPARATUS FOR CONTROLLING SHUTTER OF 3D GLASSES USING THEREOF

摘要

PURPOSE: A synchronous signal receiver, a shutter controller of three-dimensional glasses and a method thereof are provided to reduce the power consumption of shutter glasses. CONSTITUTION: A synchronous signal receiving unit(210) receives a wireless synchronous signal. A controller(220) analyzes the period of the received synchronous signal. The controller generates a mode signal in order to control the synchronous signal receiving unit. The synchronous signal receiving unit maintains a receiving state according to a mode signal.
