ABSTRACT:
A method and system that blend graphics layers and a video layer. The graphics layers may be above and below the video layer, which may be a streaming video. The graphics layers may be stored in memory, blended and stored back in memory. The blended graphics layers may be combined with streaming video and output on a display. Blending the graphics in memory may be done offline and may save processing time and improve real-time combining with streaming video. In an embodiment of the present invention, there may be several layers of graphics below the video layer, and several graphics layers above the video layer. The top graphics layers may be blended into one top graphics layer, and the bottom graphics layers may be blended into one bottom graphics layer. The top and bottom graphics layers may be then blended into one graphics layer and combined with the video layer.
