Radio mode
The receiving concept of RDS
The abbreviation RDS stands for Radio Data System, i.e. inaudible, additional information codes are transmitted by
the VHF RDS station.
The CD-7630 CD tuner can interpret this coded information which most radio stations transmit.
The most essential data transmitted is:
- Program identification (PI)
- Traffic programme (TP)
- Traffic announcement (TA)
- Programme service name (PS)
- Alternative frequency (AF)
- Programme type (PTY)
- Enhanced other networks (EON)
- Clock time (CT)
Program identification (PI)
This information allows the receiver to clearly identify a station. It enables the radio to differentiate between ranges
where the same programme is transmitted. When the reception gets weaker, the car radio only switches to a stronger
station if it transmits the same programme identification.
Traffic programme (TP)
This signal enables the receiver to detect if a traffic news station is being received.
Traffic announcement (TA)
This signal allows the receiver to detect a traffic announcement and interrupt the current playback of a different audio
source.
