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 [email protected].

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.
