PTY
Program TYpe
: a function for identifying types of programs broadcast by an RDS station.
PTYN Program TYpe Name
: a supplement to program type (PTY), specifying its nature using an 8
character alphanumeric string.
REG
Regional links
: This is mainly used in countries where national broadcasters run "region-specific"
programming such as regional opt-outs on some of their transmitters. This functionality allows the
user to "lock-down" the set to their current region or let the radio tune into other region-specific
programming as they move into the other region.
RP
Radio Paging
: software configuration to broadcast digital data. The transmission protocol is
identified with some 1A group bits.
RT
Radio Text
: a function which enables text messages to be broadcast in groups of 64 characters.
The RDS receiver must be equipped with a specific display. The RT function cannot be used on car
radios as road safety commissions have forbidden its use on board a vehicle. Only home RDS
receivers can have the advantage of this radio text system.
TA
Traffic Announcement
: a digital flag which instantaneously switches an RDS receiver onto road
information reports. At the end of the report, the receiver will automatically go back to its former
operating state.
TDC
Transparent Data Channel
: a transmission path which enables the broadcaster to broadcast
diverse types of digital data for specific services. This function is not intended for FM network
listeners.
TMC
Traffic Message Channel
: a road information system in real time, used by navigation terminals,
such as Garmin, embedded in vehicles. Messages are broadcast in "localization code" and "event
code" form conforming to EN12313-1 to 12313-5 CEN (European Standards Committee)
standards.
TNGD Transmitter Network Group Designation
: definition of the group number and range associated to
a transmitter sending paging calls.
TP
Traffic Program
: a digital flag showing RDS receivers that the allocated station is likely to
broadcast road information. The TP code does not ensure receiver switching during road
announcements; it simply lets the listener know if the station offers this type of information.
UTC
Universal Time Clock
: digital source regularly transmitting UTC (universal time) and Julian date
with time zone differential
