ABSTRACT:
A method and apparatus for superimposing a character on video for display on a video screen comprising providing a system capable of displaying a plurality of RGB pixel values on a video screen, designating a portion of the plurality of RGB pixel values to have special values, receiving video data having a first plurality of RGB pixel values for display on a video screen, superimposing a character on the video data to create a composite video having a second plurality of RGB pixel values for display on a video screen, determining if a first RGB pixel value from the second plurality of RGB pixel values is in the designated portion of the plurality of RGB pixel values, displaying the first RGB pixel value if the first RGB pixel value is not in the designated portion of the plurality of RGB pixel values, determining the special value for the first RGB pixel value if first the RGB pixel value is in the designated portion of the plurality of RGB pixel values, and displaying the determined special value for the first RGB pixel value.
