Ah, confusing. So Teletext is what is called Videotext in Germany, an
additional service on TV broadcasts? And Videotex is what we call
Bildschirmtext, the online service?

I know that there were several levels of this service, so probably an
older version allowed only simple text and block graphics, and CEPT is
the newer one. I know that they replaced it sometimes later with KIT,
which was finally fully capable of displaying graphics, but that is
obsolote now as well since they want to be an Internet provider now.
