Data System)
RDS is a broadcasting service which a growing number of
FM stations are now providing. It allows these FM stations
to send additional signals along with their regular programme
signals. For example, the stations send their station names,
and information about what type of programme they broad-
cast, such as sports or music, etc.
When tuned to an FM station which provide the RDS service,
the RDS will appear, the station frequency (and then the
station name if sent) is displayed.
The TP (Traffic Programme) will appear on the display when
the received broadcast carries traffic announcements, and
the TA (Traffic Announcement) will appear whilst a traffic
announcement is being received.
EON will appear whilst the EON (Enhanced Other Networks
information) data is being broadcast.
Note:
When the TP and TA appear at the same time, an announce-
ment is being made.
When only the TA appears, an announcement is not being
made.
