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.

EXAMPLE
       $ dvbv5-scan /usr/share/dvbv5/dvb-c/the-brownfox

       Scanning frequency #1 573000000
       Lock   (0x1f) Quality= Good Signal= 100.00% C/N= -13.80dB UCB= 0 postBER= 3.14x10^-3 PER= 0
       Service The, provider (null): digital television
       Service Quick, provider BrownFox: digital television
       Service Brown, provider (null): digital television
       Service Jumps, provider (null): digital television
       …
       Service Dog, provider (null): digital television
       New transponder/channel found: #2: 579000000
       …
       New transponder/channel found: #39: 507000000

       The scan process will then scan the other 38 discovered new
       transponders, and generate a dvb_channel.conf with several entries with
       will have not only the physical channel/transponder info, but also the
       Service ID, and the corresponding audio/video/other program IDs (PID),
       like:

       [Quick]
               SERVICE_ID = 5
               VIDEO_PID = 288
               AUDIO_PID = 289
               FREQUENCY = 573000000
               MODULATION = QAM/256
               INVERSION = OFF
               SYMBOL_RATE = 5247500
               INNER_FEC = NONE
               DELIVERY_SYSTEM = DVBC/ANNEX_A
