Abstract

PURPOSE:To enable retransmission with good quality, without requiring special line or receiver, by using a common reception equipment of television or television receiver, and performing the transmission of radio broadcast waves through the vacant channels. CONSTITUTION:With a head end device 2 of a television common reception equipment, demodulation signal of radio broadcast waves or suitable audio or audible frequency signal modulates the audio carrier frequency of television broadcast vacant channel, and this modulation wave is transmitted to a coaxial cable network 3 of television common reception equipment together with the television signal. Further, said vacant channel is selected and received at a conventional television receiver 9 at the subscriber side of the television common reception equipment, allowing to receive and listen to the radio broadcast wave or audio or audible frequency signal.
