ABSTRACT:
A method of optimizing the scheduling of the drawing of graphical elements of a multi-player display (102) in an image processing environment. Each player (801to804) is capable of operating asynchronously and deriving its source from a different video, film or other image format. Draw commands from each player are combined into short sequences known as graphics requests (1002to1004). A scheduler (821) selects the next graphics request for rendering by a graphics thread (831) based on the requirement to minimize state changes within the graphics card (208) while meeting the due time requirement of the graphics request, that is dependent upon the frame rate.
