BASIC RDS
IMPORTANT NOTE:
The Stereo Generator, Basic RDS and Dynamic RDS will work only
when the device uses MP3 or IP Audio as audio source. When Main and AUX are used, Main or
AUX MPX input will be played.
All basic elements of the RDS/RBDS are displayed on the screen –
PI, PS, RT, TA/TP
and etc.
The
Alternative frequencies
are also available, represented as a list. The number of the
AF
can be
set via the
AF Count Slider.
Once the needed quantity of AFs is set, the frequencies for each of
them should be specified.
PI/CALL
(Program Identification) – The PI code is your station’s ‘digital address’. It is a
hexadecimal code that is assigned by an appropriate broadcasting authority in most countries, but
in the United States the PI code is numerically calculated from the station’s call sign. We have
provided a calculator utility within the DB8009-MPX. An in-depth discussion of the mathematical
calculation is given in RDS/RBDS Standard. To use the PI calculator for US ‘K’ and ‘W’ call
signs, simply enter call letters into the CALL box. The hexadecimal code will automatically be
calculated into PI box. If the hexadecimal code for a US station is known, you may enter it under
PI, and then the call sign will be calculated automatically into CALL box. When PI calculator fails
to calculate PI or CALL the corresponding box will be filled with ‘
----
’.
PS (Program Service Name)
– This is the station’s “street name” that will appear on the
receiver faceplate display. The PS can be up to eight characters in length (including spaces) and
can be as simple as the station’s call letters:
KWOW
or
KWOW FM
, or a slogan:
NEWSTALK
or
LIVE 95
.
RT (Radio Text)
– This is a 64-character block of plain text that the listener can select for
visual display on the faceplate of the radio by pressing an INFO button on the receiver. This
function is not available on many automobile radios for safety reasons, which has precipitated the
frowned-upon practice of scrolling the PS field instead. The Radio Text can announce song titles
