One. Among them, regarding traffic information, a station that broadcasts a program of traffic information is always multiplexed with a traffic information identification signal, and by confirming the presence or absence of this signal, it is possible to determine whether or not the station is a station that broadcasts traffic information. You can judge. In addition, a station multiplexing the traffic information station identification signal is further adapted to add the traffic information program identification signal only during the time zone when the traffic information program is being broadcast. Therefore, by confirming the traffic information station identification signal and the traffic information program identification signal on the receiver side, the volume can be reduced if the user does not want to listen to a broadcast other than the traffic information program.
