dvbv5-scan(1) 1.26.1"" dvbv5-scan(1) NAME dvbv5-scan - DVBv5 tool for frequency scanning SYNOPSIS dvbv5-scan [OPTION]... initial-file DESCRIPTION dvbv5-scan is a command line frequency scanning tool for digital TV services that is compliant with version 5 of the DVB API, and backward compatible with the older v3 DVB API. dvbv5-scan uses by default the new channel/service file format that it is capable of supporting all types of Digital TV standards. It can also support the legacy format used by the legacy dvb-apps. A single physical channel (also called as transponder) may have several virtual channels inside it, encapsulated via a MPEG Transport stream. Those virtual channels are called as 'service' at the MPEG-TS terminology, and may have one or more audio, video and other types of elements inside it. The dvbv5-scan goal is to scan for a list of physical channels/transponders and identify there the MPEG-TS services available. The dvbv5-scan tool is smart enough to retrieve the information at the MPEG-TS Network Information Table (NIT) about other channels available on the stream. OPTIONS The following options are valid: -3, --dvbv3 Force dvbv5-scan to use DVBv3 only. -a, --adapter=adapter# Use the given adapter. Default value: 0. -C, --cc=country_code Set the default country to be used by the MPEG-TS parsers, in ISO 3166-1 two letter code. If not specified, the default charset is guessed from the locale environment variables. -d, --demux=demux# Use the given demux. Default value: 0. -f, --frontend=frontend# Use the given frontend. Default value: 0. -F, --file-freqs-only Don't use the other frequencies discovered during scan. By default, dvbv5-scan will find new transponder/physical channels and add them at the internal frequency table it uses for scan. This option disables such feature. -G, --get_frontend Use data from get_frontend on the output file. By default, dvbv5-scan will repeat the same network parameters as found at the scan file. This should work fine if the output file will be used by the same frontend. However, if you intend to use the generated file on another frontend, or wants a faster tuner, this option can be used to store the actual detected parameters, instead of the ones that came from the source channel file. -I, --input-format=format Format of the input file. Please notice that caps is ignored. It can be: channel - for dvb-apps compatible channel file; zap - for dvb-apps compatible zap file; dvbv5 (default) - for the dvbv5 apps format. -l, --lnbf=LNBf_type Type of LNBf to use 'help' lists the available ones. -N, --nit Use data from NIT table on the output file. By default, dvbv5-scan will repeat the same network parameters as found at the scan file. This should work fine if the output file will be used by the same frontend. However, if you intend to use the generated file on another frontend, or wants a faster tuner, this option can be used to store the parameters that are announced by the broadcaster via the MPEG-TS Network Information Table (NIT), instead of the ones that came from the source channel file. -o, --output=file output filename (default: dvb_channel.conf) -O, --output-format=format Output format: channel - for dvb-apps compatible channel file; zap - for dvb-apps compatible zap file; vdr - for vdr compatible zap file; dvbv5 (default) - for the dvbv5 apps format. -p, --parse-other-nit Parse the other NIT/SDT tables that could be found mainly on some DVB-C carriers. -S, --sat_number=satellite_number Satellite number. Used only on satellite delivery systems. If not specified, disable DISEqC satellite switch. -T, --timeout-multiply=factor Multiply the scan lock wait time and MPEG-TS table parsing by this factor. -U, --freq_bpf=frequency SCR/Unicable band-pass filter frequency to use, in kHz. Used only on satellite delivery systems. -v, --verbose Be (very) verbose. Useful to check if the MPEG-TS is happenning fine. This option can be used multiple times to increase verbosity. -w, --lna=LNA Enable, disable or put LNA power in auto mode. Not all frontends support it. Valid values are: 0 - disable 1 - enable -1 - auto -W, --wait=time Adds additional wait time for DISEqC command completion. -?, --help Outputs the usage help. --usage Gives a short usage message. -V, --version Prints the program version. Mandatory or optional arguments to long options are also mandatory or optional for any corresponding short options. NOTE If both --nit and --get_frontend options are used at the same time, the --nit parameters will be applied after the ones that the frontend detected. EXIT STATUS On success, it returns 0.
