ALEVT(1x)                       Teletext decoder                       ALEVT(1x)



NAME
       alevt - X11 Teletext browser


SYNOPSIS
       alevt [options]


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


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

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

       -geometry geometry
           Specifies the size and position of the windows.  Default: 40x25.

       -vbi device
           Use the given device name.  Default: /dev/vbi0.

       -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.

       -child ppp[.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.

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

       -doublefont/-df
           Instructs alevt to use double sized fonts.

       --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:

              alevt 100 300 -display foo:0 100

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

              alevt -vbi /dev/vbi0 100 -vbi /dev/vbi1 100

       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 Format Specifiers 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...
