Abstract: front page image
(EN)The invention is made in the technical field of encoding and decoding of bit sequences. The invention proposes a device for compression-encoding an input bit sequence (IBS) in which Zeroes and Ones occur equally frequent, comprising an XOR gate (XOR) adapted for receiving pairs of immediately succeeding bits of the input bit sequence (IBS) as inputs and for outputting further bits of an other bit sequence (OBS), means for adding a bit to said other bit sequence (OBS) wherein the added bit is a primary bit which is equal to a primary bit of the input bit sequence (IBS) or a last bit which is equal to a last bit of the input bit sequence (IBS), and means for encoding the other sequence. The XOR gate (XOR) transforms the input bit sequence (IBS) into the other bit sequence (OBS) which comprises more uneven frequencies of occurrence of Zeroes and Ones than the input bit sequence (IBS).
(FR)L'invention, qui porte sur le domaine technique de codage et décodage de suites de bits, propose un dispositif de compression-codage d'une suite de bits entrante (IBS) dans laquelle les zéros et les uns ont une fréquence de survenue égale, et comprenant: une porte recevant comme entrées des paires de bits de la suite IBS se succédant immédiatement et émettant d'autres bits d'une autre suite de bits OBS; un moyen d'adjonction à la suite OBS d'un bit primaire égal à un bit primaire de la suite IBS ou à un dernier bit de la suite IBS; et un moyen de codage de la suite OBS. La porte XOR transforme la suite IBS en une autre suite OBS comprenant plus de fréquences impaires de survenue des zéros et des uns que la suite IBS.
