Cable providers require specific symbol rates and modulation types:
A key feature of the dvbv5-scan initial file is its role as a starting point for . Unlike simple scan tools, dvbv5-scan only requires a single valid transponder frequency in the initial file to potentially map an entire network. Key Benefits of the Initial File dvbv5-scan(1) - Arch manual pages dvbv5scan initial file
If dvbv5-scan isn't finding any services, consider these possibilities:
Digital television scanners cannot guess where to look for channels. They need a starting point. An initial tuning file provides the exact frequency and technical parameters of at least one working transponder (or multiplex) on a cable, satellite, or terrestrial network. Key Benefits of the Initial File dvbv5-scan(1) -
dvbv5-scan -v my_initial.conf
Here, the frequency is typically listed in kHz, polarization is specified (H for horizontal, V for vertical), and FEC (Forward Error Correction) rates are defined. dvbv5-scan -v my_initial
On Ubuntu, Debian, or Fedora, you can install the standard tables: sudo apt-get install dtv-scan-tables Use code with caution.
The scanning goal of dvbv5-scan is to examine a list of physical channels (also known as transponders) and identify the MPEG-TS services available within them. A single physical channel can contain several virtual channels inside it, encapsulated via an MPEG Transport Stream. These virtual channels are called "services" in MPEG-TS terminology and may contain one or more audio, video, and other types of elements.
The output uses the same DVBv5 format as the input, making it easy to use the results for future scans or with other DVB applications. As noted in the documentation, using the -G or -N options can be beneficial if you plan to use the generated file on another frontend or want a faster tuner, as they store the actual detected parameters instead of those from the source channel file.
If you cannot find a suitable file for your location, you can create one.
