Abstract:
A video compression method may include providing and transmitting encoder commands for sequences of one or more pixels in a video frame in a YCbCr color space from a set of hierarchal encoder commands. A particular encoder command for a particular sequence may include on of a copy command, a delta command, or a make pixel command. A copy command may indicate that the particular sequence is identical to one of a previous pixel in the video frame, a pixel located above a first pixel of the particular sequence in the video frame, or a pixel in a previous video frame at a location of the first pixel. A delta command may indicate that the particular sequence includes a single pixel with color values equal to the previous pixel in the video frame combined with a signed color delta. A make pixel command may provide color values of particular sequence.
