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.
