Receiving concept RDS
The abbreviation RDS stands for Radio Data System, i.e. inaudible, additional information codes are transmitted by
the FM RDS station.
With the SD-7629 you have an SD tuner that is able to evaluate these coded data that are transmitted by most of
the radio stations.
The following important data is transmitted:
- Program Identification (PI)
- Traffic Program (TP)
- Traffic Announcement (TA)
- Program Service (PS)
- Alternative Frequencies (AF)
- Program Type (PTY)
- Clock time (CT)
Program Identification (PI)
These data help the receiver to identify a station. It enables the radio to differentiate between areas where the same
programme is transmitted. The car radio only switches to a stronger station when the reception gets weaker, if the
stronger station transmits the same programme identification
Traffic Programme (TP)
This signal enables the receiver to detect that a station with a traffic programme is being received.
Traffic Announcement (TA)
With this signal the receiver can detect a traffic announcement and interrupt the current replay of a different audio
source.
Program Service (PS)
This information tells the receiver which station it is receiving. It is directly replayed in the display of the car radio, e.g.
BAYERN 3.
