Abstract
A transmission control system for a facsimile transceiver allows two facsimile transceivers having different buffer memory sizes and decoding rates different from encoding rates to intercommunicate within a short period of time. Start and stop of encoding and insertion of fill bits are controlled on the basis of an amount of data stored in a buffer memory of a transmitting transceiver, which temporarily stores encoded data, and various conditions associated with a receiving transceiver, so that the number of bits encoded data per line is averaged over a plurality of lines. This decreases the transmission time and, thereby, increases the transmission rate without resorting to an increase in the processing rate of a reader or that of a recorder or an increase in modem rate.
