v4l supports VBI (closed captioning) via the /dev/vbi* devices, this is
in the v4l specs, and the bttv driver supports this. It should be trivial
to use any of the various VBI decoding utilities then display it in a
scrolling OSD (preferably transparent =)

Options like only CC when muted (aka, QuickCap) would be nifty as well..
