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.
The Program Service Name is automatically displayed, even on the automobile receivers. Because
of driving safety considerations broadcasters are generally discouraged from scrolling messages
in this field.As a matter of fact, it is a violation of both the CENELEC and the NRSC standards to
scroll the PS display, although the practice has become universally common.
PTY
Program Type: 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. A listing of the PTY
.
Under some programming circumstances, the PTY identifier may be made ‘dynamic,’ changing
between categories for a station that “dayparts” (changes its format for specific time periods).
The PTY code is not meant to change from song to song or to accommodate a top-of-the-hour
newscast, however.
PTYN
Program TYpe Name: The PTYN feature allows the predefined by the RDS/RBDS Standard
PTY to be further described using user-defined text (e.g. PTY=4: Sport and PTY=8: Football). The
PTYN is not intended to change the default eight characters of PTY which will be used during
search or wait modes. Its purpose is to show in details the program type once tuned to a program.
If the broadcaster is satisfied with the default PTY name, it is not necessary to use additional
data capacity for PTYN. The Program Type Name is not intended to be used for automatic PTY
selection and must not be used for giving sequential information.
RT
RadioText: 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.
Most radios have limited alphanumeric display capability, so the 64 characters of RadioText
march across the front panel, much akin those annoying LED advertising signs found in airport
buses or fast food emporia. Like the scrolling-PS implementation, RadioText can announce song
titles and performers, run special promotions or contests, or broadcast sponsors’ messages.
