PROBLEM TO BE SOLVED: To transmit a great amount of large number of capacity information by a radio through many channels by modulating and transmitting much compression data to be transmitted from a central controller after classifying, recovering and decoding them by the channel. SOLUTION: This system is composed of a central controller 10 which compresses much data and transmits them, and numbers of broadcasting equipment (a deck) 20, which are connected to the central controller 10 with a wire, receives data to be supplied, modulates the received data into a radio frequency signal and transmits it and a large number of receivers 30 which receive the radio frequency signal to be transmitted from the broadcasting equipment 20 and output it. Then, the central controller 10 compresses much data and transmits them by the wire, and after number of broadcasting equipment 20 connected to the central controller 10 with the wire receive compression data respectively and decode them, they modulate and transmit the radio frequency signal by the channel. Moreover, after many receivers 30 receive and demodulate the wire frequency signal to be transmitted from the broadcasting equipment 20, it is output through a speaker.
