Abstract
PURPOSE: To shorten the time required for growth of one screen or to reduce the transmission band by transmitting part of the whole screen for reproduction.
CONSTITUTION: Control circuit 6 controls address conversion circuit 7 according to the address control signals which are received at MODEM5 after transmission from the reception side through the circuit and then decide the address of the data to be transmitted. Thus the data of 1-screen memory 3 according to the decided address is transmitted via transmission circuit 4. The partial picture data transmitted is memorized into 1-screen memory 13 to be then reproduced through monitor picture receiver 17.
