Abstract: A method and apparatus for the detection and control of errors occurring in two-dimensionally compressed image data, which method and apparatus take particular advantage of the data structure utilized in two-dimensionally compressed image data facsimile systems. The detection and control apparatus operates as an integral part of the facsimile system and is therefore implemented by a minimum amount of additional hardware.
