## description *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. More details here: https://stefantalpalaru.wordpress.com/2016/02/04/scan-all-the-things/ . The old behaviour can be enabled with -d (--delete-duplicate-transponders). - re-enable VHF band III in Europe ## requirements - up-to-date(!) DVB kernel headers with DVB API 5.3 support ## build ```sh ./autogen.sh ./configure make ``` ## distro support #### Gentoo ```sh layman -a stefantalpalaru emerge w_scan2 ``` #### Ubuntu - Ubuntu [stable ppa](https://code.launchpad.net/~w-scan2/+archive/ubuntu/stable) - Ubuntu [git ppa](https://code.launchpad.net/~w-scan2/+archive/ubuntu/git) ## basic usage NOTE: Newer versions of *w\_scan2* need the '-c' option for specifying the country (ATSC, DVB-C and DVB-T) or '-s' for satellite (DVB-S). #### DVB-C (using Germany as country, option -c) ```sh ./w_scan2 -fc -c DE >> channels.conf ``` #### DVB-T ```sh ./w_scan2 -c DE >> channels.conf ``` #### DVB-C and DVB-T ```sh ./w_scan2 -c DE >> channels.conf && ./w_scan2 -fc -c DE >> channels.conf ``` #### ATSC (terrestrial, using United States as country) ```sh ./w_scan2 -fa -c US >> channels.conf ``` #### US Digital Cable (QAM Annex-B) ```sh ./w_scan2 -A2 -c US >> channels.conf ``` #### ATSC, both terrestrial and digital cable ```sh ./w_scan2 -A3 -c US >> channels.conf ``` #### DVB-S, here: Astra 19.2 east ```sh ./w_scan2 -fs -s S19E2 ``` NOTE: see ```./w_scan2 -s?``` for list of satellites. #### generate (dvb)scan initial-tuning-data ```sh ./w_scan2 -c DE -x > initial_tuning_data.txt ``` For more sophisticated scan options see ```./w_scan2 -h``` and ```./w_scan2 -H```. ## credits - "wirbel" Winfried Koehler <w_scan AT gmx-topmail DOT de> - the original author - "e9hack" Hartmut Birr for onid-patch (2006-09-01) - "seaman" giving his his Airstar2 for testing purposes to me - "Wicky" for testing with Airstar2/Zarlink MT352 DVB-T - "kilroy" for testing with Airstar2/Zarlink MT352 DVB-T and Avermedia - "Fabrizio" for testing with Airstar2/Zarlink MT352 DVB-T - Arturo Martinez <martinez@embl.de> for a huge bunch of tests on DVB-S/DVB-S2 - Rolf Ahrenberg for doing DVB-T/T2 tests and suggestions to improve *w\_scan* - Ètefan Talpalaru <stefantalpalaru@yahoo.com> - the *w\_scan2* fork ## license *w\_scan2* is licensed under GPLv2.
