NAME
xdtv_alevt − X11 Teletext browser (adapted to xdTV)
SYNOPSIS
xdtv -alevt_arg [options]
Write options between two quotation marks
DESCRIPTION
xdtv_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.
−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 pagenumber 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|koi8-r||koi||iso8859-7||el
Selects the character set to use. Characters not present in the selected set are replaced by similar looking symbols. (default: latin-1)
−−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:
xdtv -alevt_arg 100 300 -display foo:0 100
Write options between two quotation marks
The −child options requires a parent window. So, it must be preceeded by a parent or another child window.
When saving pages xdtv_alevt asks for a format string. Look at xdtv_alevt-cap(1). The chapter Format Specifiers gives an explanation.
xdtv_alevt has no support to set or change the TV channel. This should be done with another (not supplied) program like xdtv 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...

BUGS
There are no known bugs. If you find one, please report it to <froese [AT] gmx.de>.
It seems, the video capture drivers for linux become more stable. But be very careful when using this program. Bugs in these kind of drivers have the tendency to result in really bad system failures.
