Patent Images

1. A method for coding video data contained in image frames comprising the steps of:

  • downscaling said video data image frames;

    encoding said downscaled video data to produce base layer frames;

    generating quality enhanced residual images from said downscaled video data and said base layer frames;

    encoding said quality enhanced residual images using a fine granular coding technique to produce quality enhancement layer frames;

    upscaling said base layer and said quality enhanced residual frames;

    generating a first set of residual images from said upscaled encoded data contained base layer, and corresponding quality enhancement layer frames and said video data;

    encoding said first set of residual images using a fine granular coding technique to produce spatial enhancement layer frames.
