multimedia/w_scan2 1.0.16 DragonFly

w_scan2 is a small channel scan tool which generates ATSC, DVB-C, DVB-S/S2 and DVB-T/T2 channels.conf files.

It's based on the old "scan" tool from linuxtv-dvb-apps-1.1.0. The differences are: * no initial tuning data needed, because scanning without this data is exactly what a scan tool like this should do. * it detects automatically which DVB/ATSC card to use. * much more output formats, interfacing to other dtv software.

w_scan2 is a fork of the original w_scan from https://www.gen2vdr.de/wirbel/w_scan/index2.html

Main changes from w_scan to w_scan2: * keep duplicate transponders by default because a stronger transponder with the same ID might have a higher frequency and be discarded simply because it's scanned later. Also don't replace the current transponder with an advertised one by default. The latter may have a lower signal strength.
