Your initial file says DVBT2 , but your tuner wants DVBT or DVBC . Check your frontend’s capabilities:
It is important to note that the older scan utility uses a different format (simple space-separated values) and relies on initial files located in /usr/share/dvb/scan/ . dvbv5scan uses the .ini format, which is more flexible and supports DVBv5 features like S2 and T2.
When standard system tables are outdated or a local network changes broadcast frequencies, you must construct a custom initial scan configuration manually. dvbv5-scan - LinuxTVWiki - LinuxTV.org
tool to perform a "blind scan" which does not require an initial file. It can output a DVBv5-compatible file: w_scan2 -ft -L > initial_file.conf Convert an old one: If you have an old (v3) file, you can convert it using dvb-format-convert dvbv5scan initial file
Inside this directory, files are organized by broadcast type ( dvb-t , dvb-c , dvb-s ) and named after cities, countries, or satellites. How to Create or Update a Custom Initial File
Defines the standard (e.g., DVBT , DVBT2 , DVBS2 , DVBC/ANNEX_A ). FREQUENCY: The frequency in Hertz. BANDWIDTH_HZ: (For Terrestrial) Usually 8MHz or 7MHz.
You rarely need to write an initial file completely from scratch because the open-source community maintains a massive repository of them. Your initial file says DVBT2 , but your
A DVBv5 file consists of one or more blocks of data. Each block represents a single transponder or channel multiplexer. Blocks are separated by blank lines, and each parameter is defined using a KEY = VALUE syntax. Common Global Tags
This command takes a legacy channel file and outputs a fresh DVBv5 file that can be used with dvbv5-scan .
The tuner cannot find a signal on the specified frequency. When standard system tables are outdated or a
Locate the frequencies of at least one active mux/transponder for your region or satellite (e.g., from LyngSat). Create a New File: Create a text file. Add Parameters: Use the dvbv5 syntax shown above. Save: Save it to a known location, such as my_initial_file .
: The center frequency in Hertz (e.g., 474000000 for 474 MHz).
To convert an old legacy channel format file ( my-old-channels.conf ) to the new DVBv5 format, you can use a command like this:
