Restrictions and Recommendations for Audio, DLS and SLS files
The live Audio is recorded automatically in the system so that a playout of the last
live announcement in a loop is possible. The maximum length of a live Audio
recording is limited to 30 minutes.
To use pre-recorded Audio content for file announcements simple WAV files can be
used. Please note that the sampling frequency must be 48 kHz. All other
parameters like channels, resolution etc. will be converted automatically.
Depending on the DAB receiver it needs a few seconds until the DLS is displayed.
Some receivers show a new label first when the currently displayed label is
completely finished.
The maximum string length of a DLS can be 200 Bytes which can be less than 200
characters if unicode characters are used.
To reduce the time which is necessary to transmit a slideshow picture it is helpful to
minimize the file size of the picture. We recommend to use PNG files with less
colours. File sizes of 2 … 3 KB with the dimensions of 320 x 240 pixel (which is a
must) are perfect for a proper transmission.
Although it is possible to transmit more than one picture in a slideshow, please do
not forget that the transmission rate for SLS during an announcement is limited to
1.5 … 8 kbit/s depending on the break-in encoder bitrate. That means that a file
with 3 KB needs approx. 6 seconds to be transmitted.
