Abstract
Management of graphical overlays for use in stereoscopic video where the graphical overlay is positioned relative to depths associated with objects showing in the video. A disparity offset processor may be configured to facilitate generating overlay mapping information as a function of object depth maps in order to facilitate positioning one or move graphical overlays relative to corresponding objects.
