alevt - X11 Teletext browser
alevt [options]
alevt is an X11 program for browsing and searching Teletext pages received by a compatible decoder (at the moment, bttv).
A summary of command line options is included below. The X11 user interface is described in the built-in manual.
The -parent keyword is just for completeness and not normally used. The page number alone is sufficient. Default: 900.
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:
Or, one window from /dev/vbi0 and one from /dev/vbi1 (untested *g*):
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...
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.
/dev/vbi*
/dev/dvb/adapter*/demux*
Select the teletext stream by the PID hex value:
Select the teletext stream by the PID decimal value:
Select the teletext stream by the program name:
alevt-date(1), alevt-cap(1), X(3x), xawtv(1x), and the built-in manual.
