Abstract
The method and apparatus for efficiently storing or transmitting related sets of data such as X, Y coordinate data determines the resolution of a display device and the transmission limitations of a communication channel to the display device and encodes a selected portion of the bitmap for display with associated offsets and additional information as a complex number according to a variable-radix polynomial, where the number is segmented into selected bytes for transmission within the operating limitations of the communication channel for decoding and restoration of offsets by the display device.
