Dvbv5scan Initial File [updated] 【WORKING - Cheat Sheet】
The DVBv5 format replaces this cryptic syntax with a highly readable, key-value pair structure grouped by channel blocks. This format is standardized across all delivery systems, including satellite (DVB-S/S2), terrestrial (DVB-T/T2), and cable (DVB-C). Structure of a DVBv5 Initial File
The initial file tells the scanner where to listen. It does contain the final channel list; instead, it helps the tool discover the actual services (TV/radio programs) and their details.
The structure of these files has evolved. While older formats used a simple single-line syntax, DVBv5 files use a key-value format that is much easier to read and extend. A typical entry might look like a block of text defining the DELIVERY_SYSTEM BANDWIDTH_HZ
Using DVBV5SCAN with an initial file is straightforward. Once you have created your initial file (let's call it my_scan.ini ), you can invoke DVBV5SCAN from the command line, specifying the path to your initial file: dvbv5scan initial file
[CHANNEL] DELIVERY_SYSTEM = DVBT2 FREQUENCY = 498000000 BANDWIDTH_HZ = 8000000 MODULATION = QAM/256 # Let dvbv5scan autodetect the rest
If you are using a specific tuning adapter (for example, if you have multiple USB TV sticks plugged in), specify the adapter index using the -a flag: dvbv5-scan -a 1 my_initial_frequency.conf -o channels.conf Use code with caution.

A typical DVBv5 initial scan file is a plain text file containing a "transponder" definition. Unlike legacy formats that use a single line, the DVBv5 format uses a block-based structure:
to perform a "blind scan" and generate a file in the DVBv5 format. Debian Manpages dvbv5-scan - LinuxTVWiki - LinuxTV.org It does contain the final channel list; instead,
dvbv5-scan -o my_new_channels.conf my_initial_file.conf
This example shows the tool successfully locking onto an initial frequency (#1), identifying several services (like SBT and Globo), and then automatically adding a new discovered transponder (#2) to its internal scan list. The process then continues to scan all discovered frequencies (#2 through #39) and ultimately generates a comprehensive channel configuration file.
