Patent ID: 7340103

Claim:
A computer-readable storage medium storing computer-executable instructions for causing a computer system programmed thereby to perform a method comprising: receiving run length encoded data for a current frame in a series; and run length decoding plural pixel series in the current frame from the run length encoded data for the current frame, each of the plural pixel series being encoded as a run length and a run value, wherein the run value for at least one of the plural pixel series is a color value symbol, wherein the run value for at least one of the plural pixel series is an above color value symbol, wherein the run value for at least one of the plural pixel series is a previous frame color value symbol that references color values of pixels in a previous frame before the current frame in the series, and wherein the previous frame color value symbol indicates the color values of pixels in the previous frame are identical to color values of pixels at the same locations in the current frame.
