Kornelis A Schouhamer Immink: Method of transmitting information, encoding device for use in the method, and decoding device for use in the method. U S Philips Corporation, Thomas A Briody, William J Streeter, Edward W Goodman, October 28, 1986: US04620311 (55 worldwide citation)

A method of converting n-bit information words into m-bit code words, and the other way round, is described. The code words have a limited disparity. For every information word, two code words are assigned to a group of information words, which code words can be derived from one another by inversion ...
