RDS DATA
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.
Basic RDS
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 DB6400. 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
and performers, run special promotions or contests, or broadcast sponsors’ messages.
