<p>PURPOSE:To shorten time in which a turbulence occurs in picture displayed status at the side of a receiver (RX) by selecting a transmitting (TX) and sending a refreshing signal to the selected TX at the same time and initializing the TX. CONSTITUTION:TXs 1a-1c are provided for respective plural spots A-C, one out of the TXs 1a-1c is selected, and a high efficiency coding picture signal is transmitted through a transmission circuit L to an RX2 provided on a position D at a receiving side. A control part (CNT) 6 at a spot A is equipped with a function for sending a refreshing signal 14, sends the refreshing signal 14 simultaneously with controlling selected status at a selecting part (SEL) 3 by a selecting signal 11, and gives the refreshing signal 14 through a path simultaneously switched by the SEL3 to a selected TX1. The TX1 is initialized according to this.</p> |
