A broadcasting facsimile transceiver has a transmission controller which, in the broadcasting mode, inhibits broadcasting communications during a predetermined interval of time ranging from the completion of transmission to a destination to the commencement of transmission to the succeeding destination. The transceiver also includes a scanning unit for reading a document and delivering video data, a data compression unit for compressing the video data, a memory unit for storing compressed video data from said data compression unit, a reproduction unit for reading the compressed video data stored in said memory unit, a MODEM for transmitting the video data to a communication line. The transmission controller controls the transceiver such that when reading the document, the video data read out of the scanning unit is stored in the memory unit through the data compression unit and in the broadcasting communication mode, the video data from the data reproduction unit is transmitted to the communication line through the MODEM. During a predetermined interval of time between the termination of transmission to a first destination and the commencement of transmission to a second destination, the transmission of transmission video data is inhibited to establish a reception wait state in the transceiver.

Broadcasting communication apparatus

A high-speed G3 facsimile communication system for shortening the time required for procedure control performed before transmission of image data is started, a quiescent time intervening between the connection of a receiver equipment to the transmission line and the starting of sending the control procedure signal CED is utilized for sending out a newly provided procedure shortening signal to the receiver equipment, and upon receiving a response of the receiver equipment indicating that the receiver is capable of communicating in an optional mode other than G3 mode, the sender station sends subsequently the requisite control procedure signal from the high-speed modem thereof.
