Abstract:
1. A method for operating a graphics subsystem of a reproduction device comprising a graphics subsystem and a video subsystem for display of video information comprising auxiliary information, wherein the graphics subsystem is capable of generating left and right channel data for stereoscopic 3D display of auxiliary information in a 3D mode, and wherein the graphics subsystem is further capable of generating 2D data for 2D display of auxiliary information in a 2D mode, the graphics subsystem being switchable between the display modes, the method comprising providing 3D auxiliary information to the graphics subsystem in the 3D mode so as to provide the left channel with the left channel of the 3D auxiliary information and the right channel with the right channel data of the 3D auxiliary information, receiving a request of change the display mode from the 3D mode to the 2D mode, leaving the graphics subsystem in the 3D mode and outputting both the left channel and the right channel for display while providing 2D auxiliary information to the graphics subsystem in response to said request so as to provide the left channel and the right channel with identical 2D auxiliary information to provide a 2D display of the 2D auxiliary information, and after a time interval, switching the graphics subsystem from the 3D mode to the 2D mode.
