       alevt-cap - simple capture of teletext pages


       alevt-cap [options] ppp[.ss] ...


       alevt-cap is a simple program to capture teletext pages and write them
       to disk.  You just give it a list of pages to fetch and it will save
       them.  Nothing fancy like time-outs, page ranges, or channel name
       detection is supported.  Though, it supports different file formats -
       at the moment ascii, ansi (ascii with color escape sequences), html,
       png, and ppm.


       A summary of options is included below.

       -name filename
              Gives the filename under which the pages should be saved.  It
              may contain a couple of %-sequences (see below).  (default:

       -format format-specifier
              Sets the file format used to save pages (see below).  (default:

       -format list|help
              Lists all known file formats and their options.

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

       -finetune -4..4|auto
              Specify the fine tuning for the decoder.  For the right value
              play with alevt.  Default: 1.

       -timeout seconds
              If the pages cannot be captured in seconds, the program
              terminates with exit status 1 after saving the already captured
              pages.  The default is to wait forever.

       -charset latin-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:

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

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

       --help Show summary of options.

              Show version of program.

       Every non-option argument is taken as a page number.  Subpages may be
       given in the form where ppp is the page number and ss is the
       subpage number.  If no subpage is specified, the first transmitted
       subpage of that page is taken.  The page is saved with the prior given
       format and name.

       The filename may contain %-sequences.  The following sequences are

              %%     a single % sign.

              %e     the default extension of the selected output format.

              %p     the page number and an optional subpage number.

              %P     the page number.

              %S     the subpage number.

              %s     the page number as given on the command line.

       Between the % sign and the letter you can give a field width to which
       the replacement string should be padded.

   Format specifiers
       The output format and associated options are given by the format
       specifier.  It is made up of one or more comma separated words.  The
       first word selects the output format and the others are options for
       that format.  There are common options valid for all output formats and
       format specific (private) ones.  Some options have the form of an
       assignment.  The order of the options is free.  Only the format name
       itself must be the first word.  An example:

              The ansi is the format and reveal, and bg=none are options.

       At the moment there are only two common options: reveal, and hide.
       They control whether the hidden characters present in a page should be
       shown in the output or not.  The default is hide.

       The special format string list (or help) will give you a list of all
       supported output formats and their options.

       (The ansi format is an alias for ascii,color.)

       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.


       If the program timed out and some pages are missing the exit status is
       1.  On fatal errors the exit status is 2.


       Before starting this program, you have to set the TV channel with
       another program like xawtv of set-tv.

       If you give a page number that is never transmitted the program will
       not terminate.
