Note: The correct title of this article is dvbscan. It appears incorrectly here due to technical restrictions.
dvbscan is a basic command-line utility to produce a set of channel configuration. It emits this information to stdout.
Usage
dvbscan does not do a full-spectrum frequency scan. In order to get information on the multiplexes available, it reads this information from an existing transport. So you have to feed it this information; happily, the source distribution comes with a handy selection of transport settings for most of the available transmitters.
You should find it in the directory /usr/local/share/dvb/scan/dvb-c/ for cable, /usr/local/share/dvb/scan/dvb-s/ for satellite, or /usr/local/share/dvb/scan/dvb-t/ for terrestial TV. The name gives the country and location; for example, au-Adelaide refers to Adelaide, South Australia. To be sure, look at the beginning of the file, which should look something like this:
# Australia / Adelaide / Mt Lofty # T freq bw fec_hi fec_lo mod transmission-mode guard-interval hierarchy # ABC T 226500000 7MHz 3/4 NONE QAM64 8k 1/16 NONE
In this example, the first line gives country, town and transmitter location.
The simplest use is (for example, running from the source folder)
dvbscan dvb-t/uk-[[Winter Hill]] > channels.conf
Tzap and its siblings require a channels.conf file placed in their user config folder to operate.
There are a slew of options for those with extra DVB devices, those wanting to use VDR and for filtering radio stations and encrypted channels.
