摘要 A facsimile communication system equipped with an ARQ function for transmitting data in the form of a block between a transmitter and a receiver through a transmission route having a relatively large time delay, such as a submarine cable and communications satellite, is provided. In the system, prior to transmission of image data, a time delay in transmission of data through a selected transmission route is measured and the number of bits of data block is determined in accordance with the thus measured time delay.
