NAME
       w_scan2 - a universal ATSC and DVB blind	scanner

SYNOPSIS
       w_scan2 -fa -c _COUNTRY_ID_ [ options ]
       w_scan2 -fc -c _COUNTRY_ID_ [ options ]
       w_scan2 -ft -c _COUNTRY_ID_ [ options ]
       w_scan2 -fs -s _SATELLITE_ID_ [ options ]

DESCRIPTION
       w_scan2	scans for DVB-C, DVB-S/S2, DVB-T/T2, ISDB-T and	ATSC channels.
       Any other program accessing the DVB hardware (like e.g. VDR) has	to  be
       closed in order to avoid	conflicts while	running	w_scan2.
       w_scan2 provides	the channels in	different output formats (Default: VDR
       channels.conf). For other output	formats	see OPTIONS.

OPTIONS
       The following options are available.

       -f TYPE
	      Frontend type,
	      "a" = ATSC,
	      "c" = DVB-C,
	      "s" = DVB-S/S2,
	      "t" = DVB-T, DVB-T2 and ISDB-T [default]
	      "t1" = only DVB-T
	      "t2" = only DVB-T2
	      Depending	on "TYPE", either of the arguments  "-s"  or  "-c"  is
	      mandatory.

       -c COUNTRY_ID
	      Mandatory	 argument  for ATSC scans, cable scans and terrestrial
	      scans, see option	-f.
	      Specifies	the country where you try to scan for channels as  up-
	      percase two letter identifier, e.g.
	      DE = Germany,
	      US = United States,
	      FR = France
	      Use "-c?"	for a list of all known	identifiers.

       -s SATELLITE_ID
	      Mandatory	argument for satellite scans, see option -f.
	      Specifies	 the  satellite	 you wish to scan as uppercase identi-
	      fier, e.g.
	      S19E2 = 19.2A<degree> east,
	      S13E0 = 13.0A<degree> east,
	      S0W8 = 0.8A<degree> west.
	      Use "-s?"	for a list of all known	identifiers.

       -A N   specify ATSC scan	type
	      1	= terrestrial [default],
	      2	= cable,
	      3	= both,	cable and terrestrial.

       -o N   VDR channels.conf	format
	      2	= VDR-2.0 [default],
	      21 = VDR-2.1

       -X     generate zap/czap/xine output instead of VDR channels.conf.

       -x     generate initial tuning data output for  (dvb-)scan  instead  of
	      VDR channels.conf.

       -5     generate	initial	 tuning	 data output for dvbv5-scan instead of
	      VDR channels.conf.

       -L     generate VLC xspf	playlist (experimental)

       -M     mplayer output instead of	vdr channels.conf

       -G     generate output for Gstreamer dvbsrc plugin

       -h     show help

       -H     show expert help

EXPERT OPTIONS
       -C CHARSET
	      specifies	the output charset, i.e. "UTF-8", "ISO-8859-15"
	      use 'iconv --list' to see	full list of charsets.

       -q     quiet (repeat for	less)

       -R N   Radio channels
	      0	= don't	search radio channels
	      1	= search radio channels	[default]

       -T N   TV channels
	      0	= don't	search TV channels,
	      1	= search TV channels [default]

	      with this	option,	only the first transponder copy	is  kept,  re-
	      gardless	of  the	signal strength, so if you are in an area with
	      the same transponders being broadcast  from  different  sources,
	      this will	prevent	you from searching for services	in all of them

       -a N   use device /dev/dvb/adapterN/ [default: auto detect]
	      (also allowed: -a	/dev/dvb/adapterN/frontendM)

EXAMPLES
       scan satellite 19.2A<degree> east:
	      w_scan2 -fs -s S19E2

       scan cable (DVB), Germany:
	      w_scan2 -fc -c DE

       scan aerial (DVB), France:
	      w_scan2 -ft -c FR

       scan cable (ATSC), United States:
	      w_scan2 -fa -A2 -c US

       scan aerial (ATSC), United States:
	      w_scan2 -fa -A1 -c US

       use output format zap/czap/xine:
	      w_scan2 [	OTHER OPTIONS ]	-X

       use output format dvbscan/scan/scan-s2 initial tuning data.
	      w_scan2 [	OTHER OPTIONS ]	-x
	      NOTE: w_scan2 also performs full scans, so there is generally no
	      need for this.
