Correct scan file format?

Correct scan file format?

[Simon Liddicott]

What form should T2 multiplexes take in the DVB scan files?

In the uk-CrystalPalace scan file
<http://git.linuxtv.org/dtv-scan-tables.git/blob/HEAD:/dvb-t/uk-CrystalPalace>
the PLP_ID and System_ID are included before the frequency but in
ro-Krasnador scan file
<http://git.linuxtv.org/dtv-scan-tables.git/blob/HEAD:/dvb-t/ru-Krasnodar>
the PLP_ID is included at the end of the line and it has no System_ID.

I don't have a T2 tuner to test. Is a PLP_ID required in the scan file
as in the UK we only have one?

I presume the System_ID has been included in the Crystal Palace file
because it was known by w_scan, but is it required for T2?

Thanks,

Simon.

PLP_ID should be the very last entity to preserve compatibility.

If you have only a single stream, it wouldn't make any difference if you
have a PLP_ID or not.

System ID is used for decryption with Conditional Access. If you don't
need to use a CA module, then you can ignore it.

Thanks Manu.

Before I prepare to patch the entire UK scan files can someone confirm
that the below is acceptable:
