Beschreibung
Das avards-plugin versucht das Bildformat zu erkennen und sendet passende WSS (WideScreenSignaling) Informationen an den Fernseher. Dadurch stellt der Fernseher automatisch das passende Bildformat (4:3, 16:9, ...) ein. Manuelles Umschalten am Fernseher entfällt dadurch. Ein hinreichend aktueller DVB-Treiber (ist schon seit längeren im kernel-dvb enthalten) ist Vorraussetzung für diese Funktion.

Probleme
Das Avards-Plugin erwartet das Videodevice der fullfeatured Karte unter /dev/dvb/adapter0/video0. Hat man ein Mehrkartensystem und udev installiert, kann es passieren, dass udev die Treiber der DVB-Karten lädt. Udev kümmert sich dabei nicht um die Reihenfolge, welche Karte zuerst geladen wird, so dass es vorkommen kann, dass die fullfeatured Karte nicht unter /dev/dvb/adapter0/video0 auftaucht, sondern z.B. unter /dev/dvb/adapter1/video0. Lösungen zu dem Thema findet man im VDR-Portal. Gentoo-Benutzer sollten sich diesen Thread anschauen.

- added suppport for resizing the OSD for non-PAL resolutions

- added an option to display a message whenever WSS is changed (disabled by default) (suggested by xpix@vdrportal.de)
- added an option to select the algorithm for the calculation of the zoom mode: "best possible aspect ratio" and "display all lines" (has only in rare circumstances an effect)
- clarified current mode description in main menu
- some additions to the README to clarify prerequisites for avards
- major code restructuring for easier maintenance
- added an additional check to pass through correct OSD size from VDR setup if avards is loaded but not active
- added mode definitions to avards_service.h to have also the definitions available for other plugins
- fixed incorrect picture size returned from GetVideoFormat()
- added dutch translation for new phrases (thanks to Johan Schuring)
- replaced asprintf with cString::sprintf

- implemented SVDR Interface (suggested by Viking@vdrportal.de)
- re-built detection routine, made internal infos available for queries
- added setup option to manually choose between automatic and 'forced' WSS mode (force-mode should no longer occupy the /dev/video device!)
- write WSS Data to device only if changed
- implemented a different selection of WSS mode (currently not active but gives log messages for verification in case of difference)
