When setting up a digital video broadcasting (DVB) tuner on Linux, the dvbv5-scan tool is the industry standard for frequency scanning. Unlike older tools, it relies on a specific configuration format—often called the "initial file" or "scan file"—to define the tuning parameters.
This piece covers the file structure, where to find pre-made files, and how to write one from scratch. dvbv5scan initial file
Basic command structure:
dvbv5-scan /path/to/initial-file
113000000 QAM64 6900000 121000000 QAM64 6900000 129000000 QAM64 6900000 When setting up a digital video broadcasting (DVB)
Alternatively, you can specify a frequency range using the FREQUENCY parameter in the new format: Alternatively, you can specify a frequency range using
DELIVERY_SYSTEM = DVBC/ANNEX_A
FREQUENCY = 113000000-858000000:8000000
MODULATION = QAM64
SYMBOL_RATE = 6900000
(This tells the scanner to step 8MHz from 113MHz to 858MHz).
