w_scan1

Usage

Overview

w_scan scans for DVB-C, DVB-S/S2, DVB-T, 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_scan.
w_scan 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 (and ISDB-T) [default]
Depending on "TYPE", either of the arguments "-s" or "-c" is mandatory.

-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
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.

-k

generate channels.dvb for kaffeine 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

Options

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

(also allowed: -a /dev/dvb/adapterN/frontendM)
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

-S RATE

set DVB-C symbol rate, see table: [default: choosen by country]
NOTE: for experienced users only!!
0 = 6.9000 MSymbol/s
1 = 6.8750 MSymbol/s
2 = 6.9565 MSymbol/s
3 = 6.9560 MSymbol/s
4 = 6.9520 MSymbol/s
5 = 6.9500 MSymbol/s
6 = 6.7900 MSymbol/s
7 = 6.8110 MSymbol/s

16 = 4.0000 MSymbol/s
17 = 3.4500 MSymbol/s

-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

-l TYPE

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)

-p <file>

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 only)

Examples

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 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.
