ABSTRACT:
The embodiments of the invention include a system and method for losslessly encoding and compressing a data stream. The data stream may be an image, text or combination of the two. The data stream may be received from a computer application or peripheral device. The encoding compresses the data stream by comparing consecutive values of the data stream and encoding the data based on the difference between consecutive data values.
