These files are essential for all digital television standards, including: Terrestrial (antenna) television DVB-S/S2: Satellite television DVB-C/C2: Cable television ATSC / ISDB-T: Regional digital standards DVBv3 vs. DVBv5 Initial Files: The Crucial Difference

| Parameter | Description | Common Values | |-----------|-------------|---------------| | DELIVERY_SYSTEM | Type of DVB network | DVBT, DVBT2, DVBC/ANNEX_A, DVBS, DVBS2 | | FREQUENCY | Tuning frequency in Hz | 490000000, 113000000 | | SYMBOL_RATE | Symbol rate for cable/satellite | 6900000, 22000000 | | MODULATION | Modulation scheme | QPSK, QAM/64, QAM/256, 8PSK | | INNER_FEC | Forward error correction | NONE, 1/2, 2/3, 3/4, 5/6 | | BANDWIDTH_HZ | Bandwidth for terrestrial | 8000000, 7000000 | | POLARIZATION | For satellite systems | H (Horizontal), V (Vertical) | | INVERSION | Spectral inversion | AUTO, OFF, ON |

For example, the file for a terrestrial transmitter in London would be located at /usr/share/dvb/dvb-t/uk-London . 5. How to Create Your Own Custom Initial Tuning File

[CHANNEL] DELIVERY_SYSTEM = DVBC/ANNEX_A FREQUENCY = 113000000 SYMBOL_RATE = 6900000 INNER_FEC = NONE MODULATION = QAM/64 INVERSION = AUTO Use code with caution. dvbv5scan initial file

# Run dvbv5scan with the initial file dvbv5scan --initial=dvbv5scan.initial --scan

: Specifies the hardware standard (e.g., DVBT , DVBT2 , DVBC_ANNEX_A , DVBS , DVBS2 , or ATSC ).

repository. On most Linux distributions, you can find them in the following directories after installing the dtv-scan-tables DVBv5 Format (Modern): /usr/share/dvbv5/ Legacy DVBv3 Format: /usr/share/dvb/ (Often found under subdirectories like 2. Format of an Initial File These files are essential for all digital television

: The absolute carrier frequency expressed in Hertz (Hz).

: Tells hardware how data is encoded onto waves ( QAM/64 , QAM/256 , 8VSB , QPSK ). Locating Pre-Configured Scan Tables

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 How to Create Your Own Custom Initial Tuning

This feature will provide a flexible and user-friendly way to initialize DVB channel scanning with dvbv5scan . The initial file can be easily edited and reused across multiple scanning sessions.

: Encoding complexity, such as QAM/64 , QAM/256 , or 8VSB . Locating Pre-existing Scan Files

Once you have the file (e.g., my_initial_file.conf ), run the following command to generate a full channel list: dvbv5-scan my_initial_file.conf -o channels.conf
