NAME
dvbtune — command-line tuning application for DVB cards
SYNOPSIS
dvbtune -f frequency -p h|v -s symbol_rate -v vpid
-a apid -t tpid
DESCRIPTION
dvbtune is a simple tuning application for DVB cards supported by the
Linux DVB driver (www.linuxtv.org).
This is still very experimental - especially the XML output. The
latest version can be found at www.linuxstb.org. You can contact the
author at dave@dchapman.com.
OPTIONS
The following options are understood by dvbtune:
-c [0-3] Use DVB device [0-3]
-f freq Absolute Frequency (DVB-S in Hz or DVB-T in Hz), or L-band
Frequency (DVB-S in Hz or DVB-T in Hz).
-p [H|V] Polarity (DVB-S only)
-tone [0|1]
0 = 22 kHz off, 1 = 22 kHz on
-I [0|1|2]
0 = Spectrum Inversion off 1 = Spectrum Inversion on, 2 =
auto (Default)
-S N Symbol rate (DVB-S only),e.g. 27500
-D [0-4] DiSEqc ("Digital Satellite Equipment Control") command
(0=none)
-V vpid Set video PID (Full cards only)
-A apid Set audio PID (full cards only)
-T ttpid Set teletext PID (full cards only)
-pnr N Tune to Program Number (aka service) N
-i Dump SI information as XML
-x Attempt to auto-find other transponders (experimental)
-m Monitor the reception quality
-n dpid Add network interface and receive MPE on PID dpid
--help Print help message
--version Print version string
EXAMPLES
For simple tuning, you can just use
dvbtune -f 12188000 -p h -s 27500 -v 163 -a 104 -t 32
to tune to a satellite transponder and set the video, audio and
teletext PIDs.
dvbtune can also support DVB-T reception (currently for the UK only).
In this case, you just need to specify the frequency:
dvbtune -f 48183300
To get the DVB SI information for a multiplex, you can use the -i
option. The output of dvbtune needs some addition lines before it is a
valid XML file.
To get the DVB SI information for a multiplex, you can use the "-i"
option. The output of dvbtune needs some addition lines before it is a
valid XML file. e.g. use a script containing
echo ’<?xml version="1.0"?>’ > test.xml ; echo ’<satellite>’ >>
test.xml ; dvbtune -f freq -s srate -p pol -i >> test.xml ; echo
’</satellite>’ >> test.xml
to dump the SI for a satellite transponder.
This was done to allow you to write scripts to scan multiple
transponders and write the output to the same XML file. See the
"scripts" subdirectory for examples.
NOTES
dvbtune depends on the appropriate device nodes in /dev being present.
These are either provided automatically by devfsd or udev, or must be
made using /sbin/MAKEDEV dvb. The Debian package automatically runs
MAKEDEV if necessary on install.

AUTHOR
dvbtune was written by Dave Chapman dave@dchapman.org.
Hilmar Linder added the Switch -n that adds a network interface and
switch -m that monitors the reception quality. Changed the tuning code.
Added command line parameters for spectral inversion. Changed code to
allow L-Band frequencies with -f switch.
John Williams Added -D diseqc support, and made the 22kHz tone
automatic again.
