SYNOPSIS

9       w_scan -fa -c <COUNTRY_ID> [ options ]
10       w_scan -fc -c <COUNTRY_ID> [ options ]
11       w_scan -ft -c <COUNTRY_ID> [ options ]
12       w_scan -fs -s <SATELLITE_ID> [ options ]

DESCRIPTION

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

OPTIONS

22       The following options are available.
23
24       -f TYPE
25              Frontend type,

37              uppercase two letter identifier, e.g.

EXAMPLES

174       scan satellite 19.2° east:
175              w_scan -fs -s S19E2
176
177       scan cable (DVB), Germany:
178              w_scan -fc -c DE
179
180       scan aerial (DVB), France:
181              w_scan -ft -c FR
182
183       scan cable (ATSC), United States:
184              w_scan -fa -A2 -c US
185
186       scan aerial (ATSC), United States:
187              w_scan -fa -A1 -c US
188
189       use output format kaffeine:
190              w_scan [ OTHER OPTIONS ] -k
191
192       use output format zap/czap/xine:
193              w_scan [ OTHER OPTIONS ] -X
194
195       use output format dvbscan/scan/scan-s2 initial tuning data.
196              w_scan [ OTHER OPTIONS ] -x
197              NOTE:  w_scan also performs full scans, so there is generally no
198              need for this.
