Australian LCN is based on the UK one (I think they are identical
structure, it is just the meaning of the data which is different).
dvbscan does not pick out this info. I have a program which does if you
want to test it. (It is descriptor 83 and defined in AS4933.1). You can
view the draft document called CT-002-N0004.PDF

The DVB-S network here in NZ has implemented LCN based on the the AU
standards rather than the UK standards. At the moment I've been unable
to pull out the LCN details via dvbscan.
Performing a scan I get the following

Done.
Now I have also performed a NIT scan using dvbsnoop as shown below. I
know the official STBs here in NZ are using the LCN information so it
must be in the stream somewhere.
