: The FREQUENCY in your initial file might be incorrect, or your antenna is not connected.
Once installed, the default initial tuning files are usually stored in one of the following directories: /usr/share/dvb/dvbv5/ (Standard Dvbv5 format)
dvbv5-scan also supports the older DVBv3 format, originally used by the legacy dvb-apps suite. To use a file in this legacy format, you must specify the -I channel option to tell dvbv5-scan the format of your input file.
: dvb-format-convert -I channel -O dvbv5 legacy_file dvbv5_initial_file . Running dvbv5-scan with an Initial File dvbv5scan initial file
: The channel width, typically 8000000 (8 MHz) or 7000000 (7 MHz) for terrestrial formats.
Here is a practical example for a UK DVB-T transmitter, taken from a sample initial tuning data file for the Emley Moor station:
Make sure you are using uppercase letters for parameters like DVBT2 or HORIZONTAL . The parser is case-sensitive. : The FREQUENCY in your initial file might
While many Linux distributions include default initial files, they are often outdated. Creating your own guarantees accuracy. Method 1: Using dvb-fe-tool (Recommended)
: Define the name of the output channel file (default is dvb_channel.conf ). Example Command: dvbv5-scan -a 0 -f 0 -C uk dvb-t/uk-London -o channels.conf Use code with caution. 3. Where to Find Initial Files
: Tells the kernel driver which standard to use (e.g., DVBT , DVBT2 , DVBC/ANNEX_A , DVBS , DVBS2 ). The parser is case-sensitive
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.
The is not just a piece of configuration—it is the foundation of any successful digital TV reception on Linux. Whether you are pulling channels from a rooftop antenna, a cable wall outlet, or a motorized satellite dish, mastering the creation and use of this file transforms dvbv5scan from a source of frustration into a reliable, automated scanning powerhouse.
: It primarily uses the modern DVBv5 format , which supports all current digital TV standards (DVB-T/T2, DVB-S/S2, DVB-C, ATSC, and ISDB-T).
The initial file, or "dvbv5scan initial file," serves as a configuration file for DVBV5SCAN. This file allows users to specify various parameters and options that DVBV5SCAN will use during the scanning process. The initial file can include settings such as:
