An apparatus for compositing graphical information with video may include a source of planes of video information and a renderer to provide a rendered graphical plane and bounding information specifying multiple disjoint areas that include non-transparent pixels within the rendered graphical plane. A controller may be connected to the renderer to control compositing of the rendered graphical plane based on the bounding information. A compositor may be connected to the source, the renderer, and the controller to composite the planes of video information and only the multiple disjoint areas within the rendered graphical plane based on control information from the controller. |
