This is a "plugin" for the Video Disk Recorder (VDR).
Written by: Marcel Wiesweg <marcel.wiesweg@gmx.de>
Project's homepage: http://www.wiesweg-online.de/linux/vdr
Latest version available at: http://projects.vdr-developer.org/projects/show/plg-osdteletext
See the file COPYING for license information.
Description:
Osd-Teletext displays the teletext directly on the OSD.
Both sound and video are played in the background.
Keys:
1,...,9: insert page number
Up: page+
Down: page-
Right: sub page+
Left: sub page-
Back: close teletext plugin
All other user interaction ("Actions") is configurably assigned to the other
available keys.
You can e.g. configure that you jump to page 100 when you press Red.
In this example, the Action "Jump to 100" is assigned to key "Red".
Have a look at the plugin's setup page to learn the current assignment
and adapt it to your needs.
Available Keys: Blue, Red, Yellow, Green, Play, Stop, FastFwd, FastRwd
Actions: "Zoom", "Half page", "Switch channel", "Switch background",
"Jump to..." a specific page.
Description of the actions:
Zoom: Zoom to upper half/lower half/back to full page
Half Page: Reduce OSD window to the lower half of the screen and
display upper half/lower half/back to full size
Switch channel:Show pages of a channel different from the one currently
tuned to. This does _not_ include any tuning or channel
switching with vdr's core. You must have tuned to the
channel chosen some time before so that the pages have
been stored on disk. When you press the key associated
with that action, you are asked for the channel number.
Press OK after you entered it with the number keys.
Jump to...: Jumps to the page you configure.
Switch background: Toggles background transparency between a value
configured in setup, fully black, and fully transparent.
How to configure the key bindings:
In the plugins setup menu, you can assign one of actions to each key.
You can choose freely which actions you need, you are not forced to assign
an action to a key at all if you do not need it.
If you select "Jump to...", specify the page number in the line immediately
below.
Other Setup options:
Background transparency:
number between 0 (transparent) and 255 (black). Default is 127
(also used by VDR)
Show Clock: Toggles whether an additional clock is drawn approximately
every second.
The clock shows the current system time, not any time broadcast
via teletext. Let VDR set the system time from a transponder to
have the exact time.
Auto-update pages:
Continuously checks whether a page has changed and updates it
if yes.
OSD width, OSD height:
Adjusts the width and height of the OSD independent from VDR's
settings. The valid range is 40 to 56 for the width and 12 to
21 for the height.
Minimum user inactivity:
Sets a timeout (in minutes) for user inactivity. When this
timespan has elapsed and the user did not press any keys, the
plugin will be closed. Set to 0 to disable this. Note that
disabling timeout will also effectively disable VDR's
auto-shutdown feature as long as the plugin is active.
Key bindings: See above.
Command line options:
A few settings are given on the command line rather than in the setup menu.
Available options:
-d --directory=DIR The directory where the temporary
files will be stored.
(default: /var/cache/vdr/vtx)
Ensure that the directory exists and is
writable.
-n --max-cache=NUM Maximum size in megabytes of cache used
to store the pages on the harddisk.
(default: a calculated value below 50 MB)
-s --cache-system=SYS Set the cache system to be used.
Choose "legacy" for the traditional
one-file-per-page system.
Default is "packed" for the
one-file-for-a-few-pages system.
-t --toptext Store top text pages at cache.
(unviewable pages)
Colors:
On all sorts of output devices which are not limited as to color depth
the original teletext colors will be displayed. (Only difference: Cyan is
used instead of white to make reading easier).
On the classic full-featured DVB card and other limited devices, the colors
will be reduced to four.
The mapping is currently optimized for German ARD, ZDF and RTL. If you are
for some reason really and definitely not satisfied with my choices, edit
colormapping.h and recompile.
