Abstract:
1. A method for providing three-dimensional (3D) content via a portable multimedia device, comprising: generating, by the portable multimedia device, a composite video signal from 3D content; determining, by the portable multimedia device, a time difference corresponding to displaying the 3D content on a display device and controlling active 3D glasses, the time difference being determined based on a first calibration and a second calibration, the first calibration being performed independent of user interaction and the second calibration being based on user interaction with the active 3D glasses, the second calibration including: generating, by the portable multimedia device, a synchronization signal configured to trigger the left eye and right eye modes of the active 3D glasses corresponding to displaying the composite video signal on the display device, the synchronization signal being based on the 3D content and the time difference; and transmitting the synchronization signal from the portable multimedia device to the active 3D glasses.
