Abstract
A method and apparatus for converting the color base of an image input layer include processing that begins by interpreting a conversion flag. The processing then continues by converting the color base of the image input layer from a first color base to a second color base when the conversion flag indicates a color base conversion. Note that a color base corresponds to standardized colorometries of video signals, color space of video signals, and/or any other displaying characteristics of video signals that are standardized or may be subsequently standardized. Further note that an image input layer corresponds to a display or portion thereof (e.g., a window or a picture in picture), wherein the display is capable of presenting images from multiple video and/or graphics data sources (e.g., a television signal and a computer application).
