I believe a viable solution (at least for VDR users) would be to display
the teletext data via the DVB-S card's On Screen Display. I could provide
a font that can be used to display the 40x25 character cells of a teletext
page.

So if somebody would implement retrieving the teletext data I could make
VDR display them.
