1. A method of encoding video, comprising the steps of:

  • predefining a set of pixel-copy commands based on frame location relationships between the present pixel and other pixels;

    for the present pixel, encoding according to a hierarchy selection from;

    (1) copy-pixel encoding that makes data packets defining the number of consecutive pixels of that can be represented by copying the color of a respective pixel with a frame location relationship;

    (2) individually colored pixel encoding that makes a data packets each defining each color of the pixels in said given set of consecutive pixels;

    (3) delta value pixel encoding that makes a data packets each defining the difference between the color a current pixel and a respective pixel with a frame location relationship; and

    (4) two-color series pixel encoding that makes a data packet including each bit indicating which color, from a two-color set, applies to each of the pixels in said series of consecutive pixels, wherein pixels in said given set of consecutive pixels are comprised of colors from a two color set.
