Abstract:
1. A method of generating a sync signal for controlling three-dimensional (3D) glasses in a 3D image system, the method comprising: generating sync signal start indicator information notifying a start of a 3D glasses control sync signal, state sequence mode information indicating an operating state of the 3D glasses with regard to whether a left glass or a right glass is opened or closed, sequence duty information indicating a retaining time period of the operating state of the 3D glasses, and sync signal period information indicating a period of the 3D glasses control sync signal; generating the 3D glasses control sync signal by combining the generated sync signal start indicator information, the generated state sequence mode information, the generated sequence duty information, and the generated sync signal period information according to a set order; and transmitting the generated 3D glasses control sync signal to the 3D glasses in synchronization with an image sync signal, wherein the period of the 3D glasses control sync signal indicates a time duration from a current sync burst of the 3D glasses control sync signal to a next sync burst of the 3D glasses control sync signal, and wherein the generated sync signal period information is distinctly included in the generated 3D glasses control sync signal, distinct from the generated sync signal start indicator information, the generated state sequence mode information, and the generated sequence duty information.
