APPENDIX B – HOW TO SET UP
THE RDS1000 FOR PS NAME OR RADIO TEXT SCROLLING
The RDS1000 enables to configure the PS name or radio text from different way. The purpose
of this appendix is to explain in details how to configure the equipment to scroll a text.
First of all, remember that scrolling function of PS name or Radio text is not allowed by the
RDS recommendations: “The Programme Service name comprises eight characters, intended for
static display on a receiver. It is the primary aid to listeners in programme service identification and
selection. The use of PS to transmit text other than a single eight-character name is not permitted.
Transmission of a PS name usually takes four type 0A groups, but to allow an instant display of the PS
when a receiver pre-set is selected, the PS name is often stored for subsequent recall from memory
when a programme service is selected. The transmission and reception conditions for PS described
were designed on the basis that PS would generally be invariant. A few transmission operators have
allowed PS to change to reflect the origin of the service, for example when a regional service
switches to a national service. These changes which may occur a few times a day and have a duration
of anything between a few minutes and several hours, are acceptable, but any other dynamic
changes to PS are NOT acceptable and may cause a safety hazard by distracting a vehicle driver. A
similar effect could be experienced with dynamic text transmission of PTYN. As a result, dynamic
PS and PTYN transmissions are expressly forbidden. Similarly RT could also be distracting to a
vehicle driver; therefore the in-vehicle display of RT should normally be disabled and RT display
should be designed for end-user viewing only when manually enabled.”
KVARTA has decided to include a powerful dynamic display of PS and RT in our encoders due
to the growing requests from our customers. Before any dynamic set up be sure that your country
regulation authority allows this.
Programme Service name (PS)
This is the label of the programme service consisting of not more than eight alphanumeric
characters, which is displayed by RDS receivers in order to inform the listener what programme
service is being broadcast by the station to which the receiver is tuned. An example for a name is
"Radio 21". The Programme Service name is not intended to be used for automatic search tuning and
must not be used for giving sequential information.
RadioText (RT)
This refers to text transmissions, primarily addressed to consumer home
receivers, which would be equipped with suitable display facilities.
1. Why different configuration of the PS name?
The PS name is really important for the listener it is the simplest way to tune a receiver by
decoding the name of the station (or call letters). For this reason it is absolutely necessary, for radio,
to always broadcast this information. In the RDS1000 you can configure 3 independent PS name.
Static PS name: Call letters of the station in accordance with the RDS recommendation
Eight characters. Stored in EEPROM.
