The exact parameters required in an initial file depend entirely on your delivery medium. 1. DVB-T / DVB-T2 (Digital Terrestrial)
When standard system tables are outdated or a local network changes broadcast frequencies, you must construct a custom initial scan configuration manually.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
dvbv5scan -a 0 -f 0 -I my_dvb_t2.ini -o channels.conf
With this file, dvbv5scan will attempt each frequency sequentially, quickly building a complete channel list. dvbv5scan initial file

The goal of this feature is to create an initial file that can be used as a starting point for DVB channel scanning with dvbv5scan . This file will contain essential information about the DVB device, scanning parameters, and channel configuration.
For terrestrial TV (antenna), you must define the center frequency and bandwidth. Below is a standard DVB-T initial file for a region using UHF frequencies with 8MHz bandwidth. dvbc-initial
: The target frequency in Hertz (Hz). For example, 506 MHz is written as 506000000 . Terrestrial (DVB-T / DVB-T2) Keys
In the world of Linux-based digital television, dvbv5-scan (part of the libdvbv5 suite) has become the gold standard for scanning channels. Unlike older tools, it leverages the newer DVBv5 API to support modern standards like DVB-S2, DVB-T2, and ISDB-T. However, a successful scan requires a starting point—a .
dvbv5-scan offers several command-line options that give you fine-grained control over the scanning process. Some of the most useful ones include:
This prevents you from having to manually look up technical frequencies and typing out the keys yourself. Troubleshooting Common Scanning Issues 1. Zero Channels Found dvbv5-scan - LinuxTVWiki - LinuxTV
The LinuxTV community maintains a massive repository of initial tuning files for countries all over the world.

A dvbv5 initial file is divided into sections. Each section starts with a channel name or identifier in brackets [ ] , followed by key-value pairs defining the transponder. 1. DVB-T/T2 (Digital Terrestrial / Antenna)
