Abstract
A method and apparatus for transmitting image updates employing high compression encoding are described. New and old image pixel values are compared at corresponding coordinate positions. For coordinate positions where the values are significantly different, the new image pixel values are assigned to those coordinates unless the new image pixel value is equal to a predefined transparent pixel value. In that case, a pixel value resulting in a color imperceptibly different than the new image pixel value is assigned. On the other hand, for coordinate positions where the values are not significantly different, then the predefined transparent pixel is assigned to those coordinates. Because of the high occurrence of the transparent pixel value in many applications, the pixel values assigned in such a manner are suitable for high compression encoding and consequently, high speed transmission.
