ABSTRACT:
Method and apparatus within a multimedia system for digitally decoding video pixel data. The pixel data is decoded to 24 bits per pixel from a compressed 8 bits per pixel format. The compressed pixel data is deformatted into its separate luminance and chrominance components. The components are then differentially expanded and assigned to associated pixel elements. Predominant color transitions are designated to determine the pixel location where the chrominance components change. An interpolated chrominance component may be inserted at these color change locations to smooth out the color transitions.
