In German television text, program schedule, what is AD?
If I look on text tv, teletext, or how you would call it, to look what programs there are on ZDF I see these letters:
UT= Under Titelung für Tauben
HD = High Definition
and also:
AD
The latter seems to be new. What could it mean?
For example today page 302, Der Landarzt Verständigungsprobleme. 13.10 HD UT AD.
