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.
"a" = ATSC,
"c" = DVB-C,
"s" = DVB-S/S2,
"t" = DVB-T [default]
Depending on "TYPE", either of the arguments "-s" or "-c" is
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.
Mandatory argument for satellite scans, see option -f.
Specifies the satellite you wish to scan as uppercase
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
-k generate channels.dvb for kaffeine instead of VDR channels.conf.
-h show help
-H show expert help
import dvbscan initial_tuning_data
-v verbose (repeat for more)
-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]
-O N Other services
0 = don’t search other services,
1 = search other services [default]
-E N Conditional access / encrypted channels
0 = only Free TV channels,
1 = include encrypted channels [default]
-a N use device /dev/dvb/adapterN/ [default: auto detect]
NOTE: This option is deprecated and should be usually omitted.
-F Long filter timeout for reading data from hardware.
-t N Tuning timeout, increasing may help if device tunes slowly or
has bad reception.
1 = fastest [default],
2 = medium,
3 = slowest
-i N spectral inversion setting for cable TV
0 = off,
1 = on,
2 = auto [default]
-Q DVB-C modulation [default: choosen by country]
NOTE: for experienced users only!
0 = QAM64,
1 = QAM256,
2 = QAM128
-e extended DVB-C scan flags.
NOTE: for experienced users only!
Any combination of these flags:
1 = use extended symbolrate list,
2 = extended QAM scan
choose LNB type by name (DVB-S/S2 only) [default: UNIVERSAL],
"-l?" for list of known LNBs.
-D Nc use DiSEqC committed switch position N (N = 0 .. 3)
-D Nu use DiSEqC uncommitted switch position N (N = 0 .. 15)
use DiSEqC rotor Position file
-r N use Rotor position N (N = 1 .. 255)
-P ATSC scan: do not use ATSC PSIP tables for scan (PAT and PMT
scan satellite 19.2° east:
w_scan -fs -s S19E2
scan cable (DVB), Germany:
w_scan -fc -c DE
scan aerial (DVB), France:
w_scan -ft -c FR
scan cable (ATSC), United States:
w_scan -fa -A2 -c US
scan aerial (ATSC), United States:
w_scan -fa -A1 -c US
use output format VDR-1.7:
w_scan [ OTHER OPTIONS ] -o 7
use output format kaffeine:
w_scan [ OTHER OPTIONS ] -k
use output format zap/czap/xine:
w_scan [ OTHER OPTIONS ] -X
use output format dvbscan/scan/scan-s2 initial tuning data.
w_scan [ OTHER OPTIONS ] -x
NOTE: w_scan also performs full scans, so there is generally no
need for this.
