摘要：
A method for operating a graphics subsystem of a reproduction device for display of video information comprising auxiliary information is described. 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 of generating 2D data for 2D display of auxiliary information in a 2D mode, and can be switched between the display modes. The method has the steps of: providing 3D auxiliary information in the 3D mode, receiving a signal indicative to a change of the display mode, and leaving the graphics subsystem in the 3D mode while providing 2D auxiliary information to the graphics subsystem in response to said signal so as to provide the left and right channel with identical 2D auxiliary information to provide a 2D display of the same.
