Abstract
In facsimile coding in which the items of information contained on a two-color original consisting of individual surface elements are scanned for transmission, and in which sequence lengths are represented in lines by code words composed of binary characters, and in which a line synchronizing word is produced at the beginning of the coding of each line, address words are inserted after the line synchronizing word after a given number of transmitted binary characters, each address word indicating an address of a specific surface element of a sequence. A coder is provided in a transmitter for producing the code words and a decoder is provided in a receiver for decoding the code words. A first address unit is arranged in the coder which, after each line synchronizing word and after the particular given number of binary characters of the code words, receives the address of the particular next sequence as an address word from a first storage unit which serves to store the sequences assigned to a line and operates to emit the address at the output of the coder. A second address unit is arranged in the decoder which, after each line synchronizing word and after the particular given number of binary characters recognizes the address words and feeds them, as addresses of the particular next sequence, to a second storage unit which contains the colors of the sequences.
