dvbv5-scan can start from this single point. When it locks onto the signal and reads the NIT, it should discover all other transponders on that network, allowing for a full scan.
An initial tuning file is a plain text document that provides dvbv5-scan with a starting point. Without it, the scanner would have to blindly test every possible frequency and parameter combination across the entire radio spectrum, which takes hours.
Use the -f (full-scan) flag to prevent the scanner from using the NIT, forcing it to only use entries from the initial file: dvbv5scan initial file

The current DVBv5 format replaces the older, deprecated DVBv3 format. While DVBv3 used a single line of comma-separated values, DVBv5 uses a structured, multi-line format. This newer format is tags-based, making it easier to read and compatible with modern delivery standards like DVB-S2, DVB-T2, and ISDB-T. Structure of a DVBv5 Initial Tuning File
This article provides a deep dive into the dvbv5-scan initial file, detailing its format, how to source it, and how to use it effectively. dvbv5-scan can start from this single point
Open a text editor like nano and create a file named my_initial_frequency.conf : nano my_initial_frequency.conf Use code with caution.
: On most Linux distributions (like Ubuntu or Debian), these files are stored in /usr/share/dvb/ . Without it, the scanner would have to blindly
