Abstract

PURPOSE:To reduce the number of memories down to one and thus decrease the number of manufacturing processes, by providing the channel designating register, the data register and the replacing register each. CONSTITUTION:In case the desired channel is received at CRT6, the key groups of channel selection operating part 13 are operated to designate the channel. And thus the designated channel signal is held at register 123 via control part 121. With this signal the channel selection data within memory 11 is read out and memorized in register 125. As a result, the desired channel broadcasting is received at CRT6. The exactly same process is given to CRT7 as well for reception. And latch 14 holds the designation signal of register 123, and the channel number is displayed at display part 16. For replacement of the channel signals between CRT7 and 8, the replacement signal is delivered to control part 121, and the signal of register 123 is memorized in idle register 122. Then the signal of register 124 is memorized in register 123, and the contents of register 122 is replaced into the idle opposite register via part 121.
