FM Radio Tuner Crestron C2N-TFM
2 • FM Radio Tuner: C2N-TFM Operations Guide - DOC. 6233A
RDS/RBDS Feature
The Radio Data System (RDS), a European standard, and Radio Broadcast Data
System (RBDS), a North American standard, permit broadcasters to use a sub-carrier
frequency to transmit inaudible digital data along with their regular FM
programming to receivers equipped to process the data.
The FM Tuner circuitry is compatible with the RDS/RBDS standards; the example
program discussed later in this guide provides some typical applications of this
feature, such as the display of program type name, UTC (universal time clock) data,
program name and category, and traffic information. A typical benefit of this feature
is the ability to search for stations based on program type.
Refer to “Appendix: RDS/RBDS Function Support” on page 41 for more
information.

mode functions.
