Abstract
In one embodiment, graphics from a general-purpose computer are mixed with video images from a video source. A first interface receives the graphics, the graphics including a plurality of graphics frames, at least some graphics frames including one or more regions having pixels set to one or more predetermined color values. A second interface receives video images from the video source, each video image corresponding to one of the plurality of graphics frames. A video mixer includes logic configured to recognize pixels in the at least some graphics frames that are set to the one or more predetermined color values, and in the one or more regions where the pixels are set to the one or more predetermined color values to mix pixels from the corresponding video image with the graphics frame, to create a plurality of mixed images. One or more output interfaces outputs the mixed images.
