Scrolling texts
Due to the slow transmission times, scrolling is only useful for PS texts. Transmitting a PS text takes at least (2 transmissions * 8 characters / 22 characters per second) = 0.72 seconds. (For RadioText that's 2 * 64 / 22 = 5.8 seconds, which makes scrolling useless.)
For left scrolling, add a < character at the front of your text. To scroll at higher speeds, add multiple < characters. Right scrolling is also possible, use > for that.
Examples:
<THE BEST HITS IN TOWN
<<THE BEST HITS IN TOWN AT HIGH SPEED
3s:POWER-FM/1.5s:88.5 FM/<THE BEST HITS IN TOWN
The scrolling speed can also be adjusted using timing settings:
3t:<<THE BEST HITS IN TOWN
In the previous example, the first and last characters are displayed only very briefly. There are two possibilities to solve this.
Adding spaces:
3t:<< THE BEST HITS IN TOWN (ends here)
But it's also possible to specify different timings for different monents of the scrolling. That makes it possible to display the start and end longer than intermediate parts.
Instead of using just 2s: which sets the display time for every part of the scrolling, different values can be set for different positions.
During scrolling, the first position is called '1', the second '2' etc. The last position is also known as '-1', the one before that as '-2', etc.
So what you want is to display positions '1' (start) and '-1' (end) for 1.5 seconds, and everything in between (2 up to -2) should be broadcast 2 times (the minimum for good reception). That can be done as follows: 1=1.5s,2..-2=2t,-1=1.5s:
Examples:
1=1.5s,2..-2=2t,-1=1.5s:<THE BEST HITS IN TOWN
3s:POWER-FM/1.5s:88.5 FM/1=1.5s,2..-2=2t,-1=1.5s:<<THE BEST HITS IN TOWN
