Abstract

PURPOSE:To enable the communication for video and data signal with high reliability, by transmitting the audio information, video signal and the information other than the audio information such as data signal on the same transmission line through automatic switching in time sharing and increasing the utilization rate of transmission line. CONSTITUTION:The audio transmission and reception section 1 performing the transmission and reception of audio information, and the video transmission and reception section 2 performing the input and output of manually described character and graph, are provided and the control section 5 is connected to the section 2. The line mode command delivery section 4 and the memory 6 are connected to the control section 5, and the control section 5 is connected to the contact b of the mode selector switch 8 via the MODEM 7. Further, to the contact a of the switch 8, the output of the addition section 3 which adds the output of the section 1 and that of the section 4 is connected. Further, the transmission line 11 is connected to the contact c of the switch 8 and the line mode detection section 9 monitoring the status of the transmission line 11 is connected to the transmission line 11 to monitor the output of the addition section 3 and the output status from the MODEM 7 at the detection section 9, allowing to transmit the information other than audio information and the audio information after switching automatically in time sharing.
