18.5.1 RDS / RBDS SERVICES DESCRIBED
PI -
Programme Identification
RDS:
It contains four hexadecimal numbers ( see ‘Code’ box ): the first one assigns the broadcast country
and it is automatically provided from the application by clicking the country acronyms (see Country
Group). The second hexadecimal number assigns the coverage area profile ( i.e. national , local etc.)
Click on the most suitable item inside the Coverage Area window and the application provides the
hexadecimal corresponding number.The ‘Ref’ window contains a number from 1 to 255 (normally
assigned from the law authorities to the broadcaster). If the entire hexadecimal code is already known,
you can enter it into the ‘Code’ box.
RBDS:
In the United States the PI code is numerically calculated from the station’s callsign.
PTY
Programme Type
This is an identification number to be transmitted with each programme item and which is intended to
specify the current Programme Type within 31 possibilities (News, Sports, Rock, Pop, etc.). This code
could be used for search tuning. The code will, moreover, enable suitable receivers and recorders to
be pre-set to respond only to programme items of the desired type. There are two lists, one for the
European RDS system and one for the American RBDS specification.
DI Decoder Identification
This pull-down menu allows you to identify the kind of modulation (Stereo, Mono, etc). Stereo
modulation is assigned to STEREO, STATIC PTY, while mono is MONO, STATIC PTY.
TP Traffic Programme
It is a flag to indicate that the tuned programme carries traffic announcements. The TP flag must only
be set on programmes which dynamically switch on the TA identification during traffic announcements.
TA Traffic announcement
identification is an on/off switching signal to indicate when a traffic announcement is on air.
TA flag may also activated by proper external command provided through Input 3 of the Digital Data
Port (see EXT INP selection in the TA menu). Ref also to par. 11.10.
M/S Music/Speech
is a two-state signal to provide information on whether music or speech is being broadcast. The signal
would permit receivers to be equipped with two separate volume controls, one for music and one for
speech, so that the listener could adjust the balance between them to suit his individual listening
habits.
M/S flag may also activated by proper external command provided through Input 2 of the Digital Data
Port (see EXT INP selection in the M/S menu). Ref also to par. 11.10.
