Kornelis A Schouhamer Immink, Lodewijk B Vries: Error correction method for the transfer of blocks of data bits, a device for preforming such a method, a decoder for use with such a method, and a device comprising such a decoder. U S Philips Corporation, Jack E Haken, James J Cannon Jr, October 16, 1984: US04477903 (18 worldwide citation)

For an error correction method for the transfer of word-wise arranged data, two word correction codes are successively used, each code acting on a group of words while therebetween an interleaving step is performed. The actual transfer takes place by means of channel words for which purpose there ar ...

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, Jack E Haken, Anne E Barschall, June 7, 1988: US04750138 (6 worldwide citation)

A method for converting m-bit information words into n-bit code words and vice versa. The code words have a limited disparity in order to obtain a d.c. free code. A reduction of the low-frequency content of the spectrum is obtained by selecting the code words in such a way that the sum ##EQU1## rema ...
