23.7 HINTS AND TIPS ABOUT DYNAMIC PS MODE
When programming PS durations in Dynamic mode, two ‘gold’ rules should be taken into account. They are
related to the ‘physics’ of RDS channels and are completely independent from RDS encoder architecture.
WARNING: if the PS is constantly changed (as in the PS Scrolling mode), it is possible that
some receivers will display a mixture of old and new PS message on the same display. In some
cases, no PS will be displayed at all. This may occurs as message byte group order is not
univocally recommended by the CENELEC RDS standard and strictly depends on the
coder/decoder physical implementation. Neither the RDS encoder in the processor nor the car
receiver are faulty. In case of PS Scrolling selection, we therefore suggest to choose low display
speeds. PS scrolling and PS Sequence mode are against the broadcast regulations of
most countries: refer to appropriate ‘governing body’ for further information.
The encoder’s manufacturer can not be held responsible for uncorrect PS use!
Drivers CAN NOT look at messages displayed on their radio cars longer than a few seconds. LONG PS
SEQUENCES are therefore not only be distracting car driver but they are simply.... not read!
Furthermore, they affect the quality of RDS broadcasting overall, as the Radio Station default Name refresh
could be not frequent enough.
PS scrolling lenght has been thus intentionally limited to 32 characters, as that lenght is largely suitable for a
large set of meaningful messages.
Message synthesis... means quality in Dynamic RDS broadcasting
