RDS OPERATIONS
OVERVIEW OF THE RDS FUNCTION
Radio Data System (RDS) is a broadcasting service that allows FM stations to send additional
digital information along with the regular radio program signal. Your car stereo offers you a
variety of services. Here are just a few:
- PI (Program identification)
It is a code that identified RDS stations; it is unique for each station.
- PS (PROGRAM Service Name)
The name of current station, it is shown on the display.
- AF (Alternative Frequencies List)
The list(s) of Alternative Frequencies give information on the various transmitters broadcasting
the same program in the same or adjacent reception area. If the main frequency should get
worse, the radio will tune automatically to the strongest Alternative frequency.
- TP (Traffic Program)
If the tuned program carries Traffic Announcement, the TP indicator will turn on.
- TA (Traffic Announcement)
When an actual traffic bulletin is on air, the TA indicator will also turn on.
- PTY (Program Type Codes)
This code is used to designate the current program material being broadcast. With this feature,
you can search the programs that match the selected program type, which is chosen from a
specific list of types.
- CT (Clock Time)
This function permits to update the clock of the receiver the nation from which the station is
broadcasting (from PI). It could happen that on the display will be shown the wrong hour; this
happens because in Italy the Clock Time function is not working yet.
Notes
Depending on the country or region, not all of the RDS functions are available in Italy.
RDS may not work properly if the signal strength is weak or if the station you are tuned to is not
transmitting RDS data.
