A system is provided for the simultaneous transmission of pictures between a plurality of scanning stations and a plurality of corresponding receiver stations. The pictures to be transmitted comprise two levels of brightness such as, for example, a document having black print on a white background. Each of the scanning stations scans, in a pseudorandom fashion, its respective picture to provide an output signal indicative of the information on one of the levels of brightness, as for example, the black print information on the document. This information output signal is then multiplexed. |
