RDS as reception concept
The abbreviation RDS stands for radio data system. i.e. inaudible encoded additional information is emitted as well
by the VHF RDS station.
The BSD-3023 is an SD tuner that is able to evaluate this encoded data that is emitted by nearly every station.
The following essential additional information is transmitted:
- Programme identification (PI)
- Traffic programme ID (TP)
- Traffic announcement (TA)
- Programme service name (PS)
- Alternative frequencies (AF)
- Programme type (PTY)
- EON information (EON)
- Time (CT)
Programme identification (PI)
This data helps with clear identification of a station. It enables the radio to differentiate between areas where the same
programme is emitted. The car radio thus only switches to stronger stations when reception weakens if this station
emits the same programme identification.
Traffic programme ID (TP)
This signal tells the receiver that a station with traffic programme information is received.
Traffic announcement ID (TA)
This signal enables the station to recognise a traffic announcement and also interrupt current playback from another
source.
