Claim 17:
18. A video compression method comprising:
providing encoder commands for sequences of one or more pixels in a video stream from a set of hierarchal encoder commands, wherein the video stream is provided in a YCbCr color space, wherein at least some of the set of hierarchal encoder commands address pairs of the one or more pixels having common chroma values and different luma values, wherein the set of hierarchal encoder commands includes:
a copy command indicating that a particular sequence of one or more pixels in a video frame of the video stream is identical to a reference pixel, the reference pixel including one of:
a previous pixel in a video frame;
a pixel located above a first pixel in the particular sequence in the video frame; or
a pixel in a previous video frame of the video stream at a location of the first pixel in the particular sequence;

a delta command indicating that the particular sequence includes a single pixel with color values equal to the reference pixel combined with a signed color delta; and
a make pixel command providing color values of particular sequence; and

transmitting the encoder commands for each of the sequences of one or more pixels in the video stream over a communication channel upon generation.
