Abstract

PURPOSE:To avoid the necessity of special adaptor, by delivering normal video and audio signal on the normal channel, and delivering the normal video signal and audio subsignal on the vacant channel. CONSTITUTION:The center 1 and each home 2 are tied with the coaxial cable 3. When the audio main signal in case of audio multiplex broadcast of the center 1 is selected at the control box 12 of the home 2, the television receiver 11 can receive the normal channel signal in Japanese, and when the control box is changed over into audio subsignal in case of audio multiplex broadcast, the video is the signal on the normal channel and audio is the signal of subchannel, e.g., English, Further, the said audio subsignal is delivered to the vacant channels with the center 1.
