    converting the one or more high YUV indexes into corresponding one or more high RGB values of a high RGB table;

    converting the one or more low YUV indexes into corresponding one or more low RGB values of a low RGB table; and

    combining the one or more high RGB values with the one or more low RGB values to generate an RGB color space value.
