Abstract
Official abstract text for this publication.
An application for a three-dimensional television system includes content encoded with left/right frame indicators at a pre-determined location on each frame. For example, during display frames meant for a first eye, the set of pixels contain a first pattern while during display of frames meant for the second eye, the set of pixels contain a second pattern. A detector interfaced to the screen of the television detects the left/right indication and provides synchronization to shutters of three-dimensional eyewear. The detector is positioned over the set of pixels and determines which pattern is displayed, generating a synchronization signal based upon the patterns. The synchronization signal is then transmitted to three-dimensional eyewear where it is used to control the shutters. In some embodiments, a phased-locked loop is provided within the three-dimensional eyewear to continue operation during periods when the transmission of the synchronization signal is blocked or otherwise interrupted.
First claim
Opening claim text (preview).
What is claimed is: 1. A three-dimensional eyewear synchronization system for attachment to a television, the three-dimensional eyewear comprising: three-dimensional eyewear having a shutter system, the three dimensional eyewear receiving a sequence of frames of a three-dimensional program to be viewed via the eyewear, from the television, the frames including left-eye frames, right-eye frames and synchronization frames, the synchronization frames including a synchronization seque…
