M/S Music / S peech S witch: This flag simply indicates whether music
or speech is the primary broadcast programming. The purpose of
this function is not well explained in the respective Standards,
hence it comes as no surprise that it is not widely used.
PI Program Identification: This block of data identifies the broadcast
station with a hexadecimal numerical code, which becomes the
“digital signature” of the station. The code is assigned by the
broadcasting authority in some countries, and in the US is
calculated from a numerical encoding of station call letters. The
receiver processes the PI code to assist automatic tuning features
(station memories), and to prevent false switching to alternative
frequencies that might be shared by broadcasters in nearby
regions.
PIN Program Item Number:
A PIN can be assigned to a particular
program, becoming that program’s “digital address.” A properly
equipped RDS radio can be set to ‘wake up’ when that program
airs, or even begin recording the program in the listener’s
absence.
PS Program S ervice 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”). The Program Service
Name is automatically displayed, even on automobile receivers, so
it is intended to remain ‘static.’ Because of driving safety
considerations, broadcasters are discouraged from making the PS
‘dynamic’; that is, to alternate it between different entries.
Nevertheless, ‘scrolling PS’ is becoming more and more common.
PT Y Program T ype: The PTY data flag identifies the station format
from a collection of pre-defined categories. Many RDS receivers
are able to seek the listener’s preferred format automatically.
This means that a car radio can switch from a fading station to a
stronger one that carries the same variety of music, though not
the very same program, as provided by AF switching. The PTY
function of RDS helps a broadcaster catch ‘transient audience’
share.
The following listing defines Program Type identifiers
(programming formats) for both the original European CENELEC
standard and for the NRSC variation adopted in the US. PTY
coding is the primary difference between the two standards.
Check these out. The listing suggests that Americans are not as
much into the serious aspects of human culture as their European
cousins.
