Abstract
A video compression system compresses video frames comprising pixels defined by n-bit color values. Encoder of video compression system determines the difference between a current pixel value and a plurality reference pixel values. Encoder sends difference value to decoder. Decoder determines current pixel value by adjusting a reference pixel color value by delta value.
