C) Radio Operation

Receiving concept RDS
The abbreviation RDS stands for Radio Data System, i.e. inaudible, additional information codes are
transmitted by the RDS station.
With the CD 3994 you have a CD tuner that is able to evaluate these coded data that are transmitted by
most of the radio stations.
The following important data are transmitted:
- Programme Identification (PI)
- Traffic Programme (TP)
- Traffic Announcement (TA)
- Programme Service (PS)
- Alternative frequencies (AF)
- Programme type (PTY)
- EON information (enhanced other networks)
- Clock time (CT)
Programme 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 playback of a
different audio source.
Programme 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.
