Abstract:
1. A method for displaying digital video, comprising: decoding compressed digital video information having subsampled chroma values; separating the decoded video information into original luminance values and original chroma values; resampling the original chroma values to provide resampled chroma values for each original luminance value; providing the original luminance values to a first buffer as a first grayscale image; providing the resampled chroma values to a second buffer as a second grayscale image with opacity information, with one chroma value placed in the luminance portion of the second grayscale image and the other chroma value placed in the opacity portion of the second grayscale image; and combining the original luminance values in the first grayscale image and the resampled chroma values in the second grayscale image into a buffer for display.
