Granted: 1989-03-09
Abstract: Facsimile data signal trains are transmitted from an originating station of Group 2 or Group 3 to a destination station Group 2 or Group 3 by way of an intermediate station. The scan line frequency of the facsimile data signal trains of the second group thereby amounts to n lines/second and m picture elements/line of the originals scanned whose information content is to be transmitted by facsimile data signal trains of Group 3. In the intermediate station, data signal trains of Group 2 are converted into data signal trains of Group 3 before intermediate storage and are subsequently intermediately stored, whereas data signal trains of Group 3 are intermediately stored without conversion. The data signal trains of Group 2 received in the intermediate station are converted into data signal trains of Group 3 before they are intermediately stored by demodulation, scanning with a frequency T2=mxn Hertz and coding of the samples according to a redundancy-reducing source code method.
