RDS300/RDS500/RDS1000 User Manual 3.10
application of this information would be to enable the
receiver to search automatically for an
alternative frequency in case of bad reception of the program to
which the receiver is tuned; the
criteria for the change-over to the new frequency would be the presence
of a better signal having the
same program Identification code.
PIN - program Item Number
The code should enable receivers and recorders designed to make use
of this feature to respond to the
specific program(s) that the user has pre-selected. Use is made of
the scheduled program time, to which
is added the day of the month in order to avoid ambiguity.
PS - program Service name
This is the label of the program service consisting of not more than eight
alphanumeric characters which
is displayed by RDS receivers in order to inform the listener what
program service is being broadcast by
the station to which the receiver is tuned. An example for a
name is "Radio 21". The program Service
name is not intended to be used for automatic search
tuning and must not be used for giving sequential
information.
PTY - program Type
This is an identification number to be transmitted with each program item and
which is intended to
specify the current program Type within 31 possibilities. 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 program
items of the desired type. The last number, i.e. 31, is reserved for an alarm
identification which is
intended to switch on the audio signal when a receiver is operated in a waiting
reception mode.
PTYN - program TYpe Name
The PTYN feature is used to further describe current PTY. PTYN permits
the display of a more specific
PTY description that the broadcaster can freely decide (eg PTY=4: Sport
and PTYN: Football). The
PTYN is not intended to change the default eight characters of PTY which
will be used during search or
wait modes, but only to show in detail the program type once tuned to
a program. If the broadcaster is
satisfied with a 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.
RP - Radio Paging
The RP feature is intended to provide radio paging using the existing VHF/FM
broadcasts as a transport mechanism, thereby avoiding the need for a dedicated network of
transmitters. Subscribers to a paging service will require a special pocket paging receiver in which the
subscriber address code is stored.
RT – RadioText
This refers to text transmissions coded in accordance to the RDS/RBDS standards,
primarily addressed
to consumer home receivers, which would be equipped with suitable display
facilities.
TA - Traffic announcement identification
This is an on/off signal to indicate when a traffic
announcement is on air. The signal could be used in
receivers to:
1. switch automatically from any
audio mode to the traffic announcement
2. switch on the traffic announcement automatically when
the receiver is in a waiting reception mode and
the audio signal is muted
3. switch from a program to
another one carrying a traffic announcement, according to possibilities
available through EON.
After
the end of the traffic announcement the TA must be restored to ‘OFF’.
TDC - Transparent Data Channels
The transparent data channels consist of 32 channels, which may
be used to send any type of data.
