Abstract

Abstract Translated from French L'invention a pour objet une installation de transmission de fac-similé à réduction de répondance comportant à l'émission des moyens permettant d'élaborer des mots de longueur de plage à partir des données binaires d'analyse du document Selon l'invention, à l'émission un ensemble de circuits de logique combinatoire de logique combinatoire de préférence de type PLA est programmé pour assurer le transcodage des mots de longueur de plage en d'autres mots, en utilisant un code de Huffman tronqué et, à la réception, des ensembles de préférence également de type PLA assurent un transcodage inverse. Application : transmission de fac-similé. The subject of the invention is a response reduction facsimile transmission installation comprising, on transmission, means making it possible to produce words of track length from the binary analysis data of the document According to the invention, on transmission a set of combinatorial logic combinational logic circuits, preferably of the PLA type, is programmed to ensure the transcoding of the run-length words into other words, using a truncated Huffman code and, on reception, sets, preferably also of the PLA type, provide reverse transcoding. Application: facsimile transmission.
