Abstract
PURPOSE:To make it possible to detect automatically a music broadcast at a reception side, by transmitting a control signal for discriminating the music broadcast from other broadcasts simultaneously with the music broadcast. CONSTITUTION:Signals of a music broadcast and other broadcasts are sent to FM modulator 2 selectively through change-over switch 1. Then, AM modulator 3 is supplied with a control signal for discriminating the music broadcast from other braodcasts. A modulated wave from modulator 2 includes the control signal as well as an audio signal in case of the music broadcast. Therefore, the reception side can automatically detect the music broadcast by detecting the control signal.
