Once your initial file is saved, run the scan from your terminal window. The basic syntax requires specifying the path to your newly created file. dvbv5-scan /path/to/your/initial_file -o channels.conf Use code with caution. Useful Command Flags
If scanning yields zero services, follow this diagnostic flowchart:
The tool will probe each frequency listed, detect actual services, and output the final channel parameters.
For DVB-S (satellite): Remember that the frequency in the initial file is the (950-2150 MHz). If you enter 12.5 GHz (12500000000 Hz), the tuner will fail. Convert: Actual satellite frequency minus LOF (Local Oscillator Frequency). dvbv5scan initial file
For DVB-C (cable), entries may include SYMBOL_RATE and MODULATION (e.g., QAM256 ). For DVB-S/S2 satellite, you'll find SYMBOL_RATE , POLARIZATION , FREQ in MHz, etc.
If your local transmitter has changed frequencies, or if your city is missing from the dtv-scan-tables package, you can manually create an initial tuning file using a basic text editor. Step 1: Find your local broadcast details
The DVBv5 format introduces a structured, key-value pair system. Each transponder configuration is separated into its own block. This allows the format to be completely extensible, meaning new hardware capabilities and transmission properties can be added without breaking backward compatibility. Anatomy of a DVBv5 Initial File Once your initial file is saved, run the
Save it as myscan.conf and point dvbv5-scan toward it. Troubleshooting "No Signal" Errors

A V5 initial file consists of one or more blocks of data. Each block represents a single transponder and begins with a section descriptor, followed by key-value pairs defining the technical parameters. Useful Command Flags If scanning yields zero services,
An (often called an initial scan file or transponder file) is a text-based configuration file that provides dvbv5-scan with the necessary parameters to tune into at least one digital transponder or multiplex, according to the LinuxTVWiki .
