I don't know about EIA standards.. the captions are send via VBI teletext
pages (as far as I can tell).
a seperate stream in the dvb transport tells which page the captions are
If the theme obeys the position information that the tv station is sending
with the text, then something is broken. If I take a 16:9 theme (metalurgy
for example) then the text is moved to the midle of the lefthand side of the
screen, instead of bottom center. And if I use grey-osd, then it is placed
where it should be. So something tells me that it is defined in the theme,
where to place subtitles!?!?
