6 GLOSSARY
AF : Alternative Frequencies list
The list(s) of alternative frequencies give information on the various transmitters broadcasting the same program in the
same or adjacent reception areas, and enable receivers equipped with a memory to store the list(s), to reduce the time for
switching to another transmitter
DI : Decoder Identification and dynamic PTY indicator
These bits indicate which possible operating modes are appropriate for use with the broadcast audio and to indicate if PTY
codes are switched dynamically.
IH : In House application
This refers to data to be decoded only by the operator. Some examples noted are identification of transmission origin,
remote switching of networks and paging of staff. The applications of coding may be decided by each operator itself.
M/S : Music/Speech switch
This 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.
PI : Program Identification
This information consists of a code enabling the receiver to distinguish between countries, areas in which the same program
is transmitted, and the identification of the program itself. The code is not intended for direct display and is assigned to each
individual radio program, to enable it to be distinguished from all other programs.
PIN : program Item Number
The code should enable receivers and recorders designed to make use of this feature to respond to the particular program
item(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.
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.
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.
