All the subtitles on the DVB-T channels on freeview that I have seen
use bitmap subtitles. There are text based subtitle formats in use that
are embed in the VBI like the teletext subtitles in Europe and I think
the CC stuff in the states but there are no DVB-T channels in the UK
that still use them TTBOMK.
