This is a "plugin" for the Video Disk Recorder (VDR). Initially Written by: Marcel Wiesweg <marcel.wiesweg@gmx.de> Original Project's homepage (EOSL): http://www.wiesweg-online.de/linux/vdr Latest version available at: https://github.com/vdr-projects/vdr-plugin-osdteletext See the file COPYING for license information. Alistair Buxtons bitmap2ttf (https://github.com/ali1234/bitmap2ttf) was used to create teletext2.ttf from tv-fonts 1.1 (c) 2002 Gerd Knorr <kraxel@debian.org> (https://www.kraxel.org/releases/tv-fonts/). The original fonts are public domain. Description: Osd-Teletext displays the teletext directly on the OSD. Installation: You need to install the teletext2.ttf font in order to render special graphics characters properly. Usage: 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, Stop, FastFwd, FastRwd, Ok Actions: "Zoom", "Half page", "Switch channel", "Switch background", "Config", "24-Line-Mode", "Answer", "Pause" "Hotkey Level+", "Hotkey Level-" "OSD Preset+", "OSD Preset-" "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. In case a channel is on same transponder or an additional free tuner is availabe it will change the receiver ("tuned" mode). If not, it stays in "chached" mode and only display pages which were received during tuning to selected channel in the past and pages are stored on disk already. 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. Without providing a channel, OK switches back to live channel Jump to...: Jumps to the page you configure. Switch background: Toggles background transparency between a value configured in setup, fully black, and fully transparent. Config: Enter OSD configuration mode, currently supported Left,Top +/- Width,Height +/- Frame +/- Text Vertical Offset +/- Background Transparency +/- 24-Line-Mode: Toggle Hotkey line (line 25) or add even Hints lines (line 26+27) Answer : Display concealed chars (toggle) OSD will display yellow '?' in case page contains concealed chars OSD will display green '!' while concealed chars are displayed Pause : Stop updating page (toggle) OSD will display red '!' while paused OSD will display green '>' after release (until next page update) ** if enabled/active ** Hotkey Level+ : Change to next Hotkey level (incl. rollover) Hotkey Level- : Change to previous Hotkey level (incl. rollover) Recommended assignment: FastFwd: Hotkey Level+ FastRwd: Hotkey Level- ** if enabled/active ** OSD Preset+ : Change to next OSD preset (incl. rollover) OSD Preset- : Change to previous OSD preset (incl. rollover) Recommended assignment: Stop: OSD Preset- Play: OSD Preset+ 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: 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. Color Mode 4bpp: Enforce 16-color mode (for some older DVB cards) 24-line mode Display (and scale for) only 24 lines 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. ** optional with multi-preset support ** OSD Presets visible Limit maximum visible presets OSD left, OSD top: Adjusts the left and top edge of the OSD independent from VDR's settings. The valid range is 0% to 90% OSD width, OSD height: Adjusts the width and height of the OSD independent from VDR's settings. The valid range is 10% to 100% Frame: Adjust black surrounding frame sized by amount of pixel Font: Select the font to display text Text Vertical Offset: Adjust the vertical offset by amount of (scaled) pixels The valid range is -10 to 10 (and depending on selected font) Background transparency: number between 0 (black) and 255 (transparency). Default is 128 Hotkey (color key) bindings: See above, optional with multi-level support 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) -k --key-levels=NUM Maximum amount of Hotkey levels selectable and stored default: 1 (which deactivate this feature) maximum: 9 levels -o --osd-presets=NUM Maximum amount of OSD presets selectable and stored default: 1 (which deactivate this feature) maximum: 9 presets -P|--debugpage <int|hexint> Specify page to debug (int: autoconvert internally to hex) -S|--debugpsub <int|hexint> Specify sub-page to debug (int: autoconvert internally to hex) -L|--debugline <int> Specify line of page to debug -D|--debugmask <int|hexint> Enable debugmask (see logging.h for details) 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.
