Abstract

PURPOSE:To realize efficient picture communication by selecting a transmission start signal depending on the establishment of negotiation and applying high speed transmission of picture information at a transmission speed corresponding to the transmission start signal so as to attain the transmission suitable for equipments or lines. CONSTITUTION:At the time of sending a negotiation start signal and detecting a response signal with respect to the negotiation signal within a prescribed time by the control of a CPU2, after the equipment at the sender receives the 1st transmission start signal for a prescribed time, the picture information is sent in the 1st transmission mode corresponding to the 1st transmission start signal by a high speed MODEM 5. When no response signal is detected within the prescribed time, after the 2nd transmission start signal different from the 1st transmission start signal is sent for a prescribed time, the picture information is sent in the 2nd transmission mode corresponding to the 2nd transmission start signal by the high speed MODEM 5. At the time of detecting the negotiation start signal for a specified time in the equipment at the receiver side, the response signal to the negotiation start signal is sent and at the time of detecting the transmission start signal for a specified time, the equipment receives the picture information in the transmission mode corresponding to the received transmission start signal.
