ABSTRACT:
A method and apparatus for processing signals for display using a single frame buffer. In a preferred embodiment, a plurality of pixels are received, wherein one or more of the plurality of pixels corresponds to a first display and one or more of the plurality of pixels corresponds to a second display. A display bit map and a display mask are generated in accordance with the plurality of pixels. If a pixel of the plurality of pixels corresponds to the first display and a corresponding mask field of the display mask has a first-display value, then the pixel is stored in the display bit map, wherein the mask field comprises at least one mask bit. Otherwise, if the pixel corresponds to a key color, then the mask field corresponding to the pixel is set to the first-display value. Otherwise, the pixel is stored in the display bit map and the mask field corresponding to the pixel is set to a second-display value.
