Abstract
In facsimile transmission by means of a redundancy reducing coding, for example run-length coding, a distance affects the entire remaining portion of the picture line. End-of-line control characters are therefore transmitted for line synchronization. As these characters are possibly also disturbed and the picture lines to be printed would then completely be lost, a fixed number of different end-of-line control characters are used in cyclic sequence from line to line. This enables the recognition of various successive disturbed picture lines, lost end-of-line control characters as well as end-of-line control characters artificially produced by a disturbance, so that the correct number of picture lines is always printed. Corrected picture lines are printed instead of the picture lines which were received in a disturbed manner, for example by taking over the contents of adjacent picture lines.
