CONFERENCE COMMUNICATION SYSTEM

摘要

PURPOSE:To attain multi-destination conference over two stations by providing a a changeover switch exclusive for receiving to each conference communication device and suppressing frame transmission from a corresponding conference communication device when the receiving mode is selected by this changeover switch. CONSTITUTION:A diagram or the like described on a white board 11 is read by an input processing section 12 via a switch SW2. The input processing section 12 compresses intput information and applies packeting to the information. The information formed into a packet is outputted to a transmission receiving processing section 13 via a mixer 15 and a switch SW5 for transfer. The transmission and reception processing section 13 executes both the transmission and reception when the switch SW1 is turned on and executes only the reception when the switch SW1 is turned off. The picture information transmitted from the other station via an MODEM 14 is decomposed into packets at the transmission and reception processing section 13 and outputted to the mixer 15. The mixer 15 mixes the received picture information and the output information of the input processing section 12 in the unit of packets. An output of the mixer 15 is outputted to a floppy processing section 16 and a picture display processing section 17.
