In DVD subtitles, the subtitles are actually pictures (bitmaps),
see this for example:
http://panteltje.com/panteltje/dvd/frame40884.bmp
The black area is made transparent in the picture.
There is a limited 'palette' and only 4 'colors' can be selected at any time
from that palette (one will normally be an dark 'outline' to make white text
visible in white areas).
I do not know how the new DivX6 subtitles will work.
A clear advantage of bitmaps is that you can have any character set supported.
A .srt text file subtitle format looks simply like this:
1
00:05:01,760 --> 00:05:04,160
Van de hele wereld bevolking
2
00:05:04,160 --> 00:05:07,360
zullen relatief maar heel weinig mensen horen over die leraar
How the text is displayed (in what font, fontsize, and color) is
set by the player itself.
So you have full control (if the player allows).
When you have 'embedded subs' you select a subtitle font, color, and size
and render the subs permanently in the movie.
You have full control over how it looks (better then bitmaps and you can
make any color), but the user cannot switch the subtitles off.
This I have solved in some cases by supplying a version with and one without
subs on the same disk.
