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 terminol-
       ogy,  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	 chan-
       nels/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.

       -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 de-
	      fault, 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  an-
	      nounced  by  the broadcaster via the MPEG-TS Network Information
	      Table (NIT), instead of the ones that came from the source chan-
	      nel 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  ver-
	      bosity.

       -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  de-
       tected.

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 transpon-
       ders, and generate a dvb_channel.com with  several  entries  with  will
       have  not only the physical channel/transponder info, but also the Ser-
       vice 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
