LINUX                                                 1.8.2                                            ALEVT(1x)

alevt  is  an  X11 program for browsing and searching Teletext pages received by a compatible decoder (at
       the moment, bttv).

       Select the teletext stream by the PID hex value:

              alevt-vbi/dev/dvb/adapter0/demux0-pid0x0237

       Select the teletext stream by the PID decimal value:

              alevt-vbi/dev/dvb/adapter0/demux0-pid567

       Select the teletext stream by the program name:

              alevt-vbi/dev/dvb/adapter0/demux0-progname´kabeleins´

/dev/vbi*/dev/dvb/adapter*/demux*

       A summary of command line options is included below.  The X11 user interface is described in the built-in
       manual.

       -displaydisplay
           Where to display the windows.  Default: $DISPLAY.

       -geometrygeometry
           Specifies the size and position of the windows.  Default: 41x25.

       -vbidevice
           Use the given device name.  Default: /dev/vbi, /dev/vbi0, /dev/video0, /dev/dvb/adapter0/demux0 tried
           in this order.

       -finetune-4..4|auto
           Try some fine tuning if you have a lot of decoding errors (these  lightning  symbols).   This  allows
           fine tuning of the decoder circuit.  The pre finetune behaviour was -finetune 0.  Default: 1.

       [-parent]ppp[.ss]
           Open a new window with the page number given by ppp and an optional subpage index given by ss.

           The  -parent  keyword  is  just  for  completeness  and  not normally used.  The page number alone is
           sufficient.  Default: 900.

       -childppp[.ss]
           Open a new child window with the page number given by ppp and an optional subpage index given by  ss.
           About the concept of parent and child windows see the built-in manual.

       -erc/-noerc
           Enables/disables  the  error  reduction  code  which  substitutes  errors  on  a  page by data from a
           previously received one.  Enabled by default.

       -bell/-nobell
           Enables/disables the error bell.  Normally enabled.

       -charsetlatin-1|latin-2|koi8-r|iso8859-7
           Selects the character set to use.  Characters not present in the selected set are replaced by similar
           looking symbols.  (default: latin-1)

       -prognamename
           Specifies the program name if using the DVB interface.

       -pidpid
           Specifies the teletext PID if using the DVB interface.

       --help
           Show summary of options.

       --version
           Show version of program.

       The order of options is important!  Each page number  opens  a  new  window  with  the  previously  given
       geometry,  device, and display.  For example, to open two windows on the local display and one on display
       foo:0 you would start it with:

              alevt100300-displayfoo:0100

       Or, one window from /dev/vbi0 and one from /dev/vbi1 (untested *g*):

              alevt-vbi/dev/vbi0100-vbi/dev/vbi1100

       The -child options requires a parent window.  So, it must be  preceded  by  a  parent  or  another  child
       window.

       When  saving  pages alevt asks for a format string.  Look at alevt-cap(1).  The chapter FormatSpecifiers
       gives an explanation.

       alevt has no support to set or change the TV channel.  This should be done with  another  (not  supplied)
       program  like  xawtv  or  set-tv  from  the  xawtv  package.   Maybe  in  the future there will be a more
       sophisticated method in bttv to switch channels etc with a dedicated  tuner  application.   But,  at  the
       moment, you have to live with it...

       The -progname or -pid option specifies the program or teletext PID if using the DVB interface.

       If  neither  of  these  two  options  is  used, alevt outputs informations about the currently accessible
       streams and uses the first of these PIDs as default. This output contains the PIDs and names that can  be
       used as an input for the -progname or -pid option in the context of the currently chosen TV channel.
