Hi Mircea,
DLS and DL+ are not part of the DAB multiplexer, but of the audio
encoder; PAD stream is multiplexed inside the audio stream. CRC-DABPLUS
has an experimental feature for DLS, but DL+ is not directly supported.
If I'm not wrong, DL+ is DLS with XML tags, so it could be added
externally and send to the DLS input. Please note that CRC-DABPLUS is
not an open source project.
Sorry, CRC-DABMUX does not support dynamic change of Service information.
Regards,
Pascal
