Each entry provides the necessary parameters—frequency, modulation, bandwidth, etc.—for the tool to lock on to a specific, known, active digital signal.

For over-the-air digital TV, an initial file entry typically looks like this:

The initial file is a plain text file. It defines the delivery system (e.g., terrestrial, cable, satellite) and lists specific frequencies or transponders to probe. dvbv5scan initial file

The tool offers numerous options to customize its behavior:

Without an initial file, dvbv5scan is like a metal detector with no clue what it’s looking for. With it, the tool knows precisely which frequencies to probe, what bandwidth to use, and what modulation schemes to expect. The dvbv5scan tool needs to know where to

For advanced users: You can create a comprehensive initial file for an entire city or satellite. Collect all known frequencies and multiplex parameters from public sources (like ukfree.tv or lyngsat.com ), then create an .ini file with multiple [CHANNEL] sections.
