Abstract

PURPOSE: To enable to transmit the video signal added to the audio information, by transmitting the audio signal to the speaker and selecting the audio reception condition to the video information reception state with the timer output for a given time elapsed.
CONSTITUTION: The signal transmitted from the transmission side information center 1 is converted into digital signal at the reception side demodulator 12, audio code is discriminated at the audio identification code judgement circuit 18, the timer 22 is operated with the detection signal, and the audio signal is delivered to the speaker 11. Further, after a given time elapsed, FF21 is reset and the output of the timer 22 selects the audio information reception state into video information reception state. Thus, the video signal can be transmitted added to the audio signal.
