– PTYN (programme type name): this field can be used for detailed description of the
PTY by 8 digits. Example: if the PTY is 4 (Sport) a PTYN like "Football" could be
transmitted. The PTYN is intended for displaying additional information only and
cannot be used for automatic station tuning like the PTY. The PTYN is optional. Default
is blank.
– Music/Speech : select Music or Speech. Default is Speech.
– Traffic Info : select None, TA (Traffic Announcement), TP (Traffic Programme) or
TA+TP. The receiver can often be set to pay special attention to this flag and, for
example, stop the tape/pause the CD or retune to receive a traffic bulletin. The TP flag
is used (set to 1) to allow the user to find only those stations that regularly broadcast
traffic bulletins whereas the TA flag is used (set to 1) to signal an actual traffic bulletin in
progress. These flags are set to 0 if they are not being used for traffic information.
Default is None.
– Alt. Frequencies : select None or 1 through 25. This allows a receiver to re-tune to a
different frequency providing the same station information (i.e., using translators or
repeaters) when the first signal becomes too weak. This is often utilized in car stereo
systems. Default is None.
– Artificial Head (bit 1 of DI, see NOTE below): select Enabled or Disabled. This
selection is a decoder identification operating mode flag. Default is Disabled.
– Compression Flag (bit 2 of DI, see NOTE below): select Enabled or Disabled. This
selection is a decoder identification operating mode flag. Default is Disabled.
– Dynamic PTY (bit 3 of DI, see NOTE below): select Dynamic or Static. This selection
is a decoder identification operating mode flag. Default is Static.
– Stereo (bit 0 of DI, see NOTE below): select Stereo or Mono. This selection is a
decoder identification operating mode flag. Default is Mono.
Note:
Artificial Head, Compression Flag, Dynamic PTY and Stereo are part of the DI (Decoder Information)
data (see UI editing screens on
Figure 2.66 on page 2-88 ). RDS Data is provided as a single-digit hex
input between 0 and F, that encodes the flags for the four settings as a 4-bit code. For example: hex number
3 is bit-represented by 0011, from bit 3 on the left to bit 0 on the right. This number is decoded to mean
Stereo = Yes/Stereo (bit 0=1), Artificial Head = Yes/Enabled (bit 1=1), Compression = No/
Disabled (bit 2=0) and Dynamic PTY = No/Static (bit 3=0).
