ALEVT(1x) Teletext decoder ALEVT(1x)NAMEalevt - X11 Teletext browser
SYNOPSISalevt [options]
DESCRIPTIONalevt 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 cir‐
cuit. 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
Selects the character set to use. Characters not present in the
selected set are replaced by similar looking symbols. (default:
latin-1)
-progname (dvb only)
Selects the station name to display.
-pid (dvb only)
Selects the station pid to display.
-outfile (dvb only)
Specifies a file where the available stations are written.
--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.
To access the DVB interface, use:
alevt-vbi /dev/dvb/adapter0/demux0
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 applica‐
tion. But, at the moment, you have to live with it...
