Hi,
thanks for the informative article.
I just want to add that besides w_scan which you can also install with
sudo apt-get install w-scan
for DEB-based systems there´s also w_scan2
w_scan2 is an application which scans frequencies for ATSC, DVB-T2, DVB-C and DVB-S / S2 without region-specific data (the so-called “initial tuning data”)
and then in turn generates data that is required by many TV applications for the reception of DVB stations
(translated from: w-scan2 › Wiki › ubuntuusers.de )
Main difference seems to be:
w_scan: ATSC, DVB-T, DVB-C und DVB-S/S2
w_scan2: ATSC, DVB-T2, DVB-C und DVB-S/S2
So w_scan2 supports the newer DVB-T2 standard.
Many greetings
Rosika
