       w_scan - a universal ATSC and DVB blind scanner


       w_scan -fa -c <COUNTRY_ID> [ options ]
       w_scan -fc -c <COUNTRY_ID> [ options ]
       w_scan -ft -c <COUNTRY_ID> [ options ]
       w_scan -fs -s <SATELLITE_ID> [ options ]


       w_scan  scans  for  DVB-C, DVB-S/S2, DVB-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_scan.
       w_scan  provides the channels in different output formats (Default: VDR
       channels.conf). For other output formats see OPTIONS.


       The following options are available.

       -f TYPE
              Frontend type,
              "a" = ATSC,
              "c" = DVB-C,
              "s" = DVB-S/S2,
              "t" = DVB-T [default]
              Depending on "TYPE", either of the arguments  "-s"  or  "-c"  is

       -c COUNTRY_ID
              Mandatory  argument  for ATSC scans, cable scans and terrestrian
              scans, see option -f.
              Specifies the country where you try  to  scan  for  channels  as
              uppercase 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
              identifier, e.g.
              S19E2 = 19.2° east,
              S13E0 = 13.0° east,
              S0W8 = 0.8° 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
              6 = VDR-1.2 .. VDR-1.6 [default],
              7 = VDR-1.7 (for DVB-S2 support)

       -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.

       -k     generate channels.dvb for kaffeine instead of VDR channels.conf.

              NOTE: w_scan also performs full scans, so there is generally  no
              need for this.
