Patent ID: 8306387

Claim:
A playback apparatus that executes stereoscopic playback, the playback apparatus comprising: a video decoder operable to decode a video stream to obtain video frames; a video plane that holds the video frames; a graphics plane that holds graphics data, the graphics data having a resolution of a predetermined number of horizontal and vertical pixels; a compositer operable to composite the graphics data within the graphics plane with one of the video frames; and a shift engine operable to perform plane shifting of the graphics plane, wherein each of the video frames in the video plane is output as one of a right-view video frame and a left-view video frame, and the plane shifting of the graphics plane includes: prior to compositing the left-view video frame by the compositor, shifting each pixel of pixels of the graphics data within the graphics plane in one of a right direction and a left direction; prior to compositing the right-view video frame by the compositor, shifting each pixel of the pixels of the graphics data within the graphics plane in an opposite direction from a shift direction of the graphics data prior to compositing the left-view video frame, and then transmitting resulting shifted graphics data within the graphics plane to the compositer for composition; cropping a first rectangle area on an end portion of the graphics data in the one of the left direction and the right direction in which the shifting prior to compositing one of the left-view video frame and the right-view video frame is performed; and adding a second rectangle area composed of transparent pixels to an opposite end of the end portion where the cropping is performed, in the graphics data of the graphics plane.
