Are you talking about digital TV? If so, that's completely different
and you probably want to use something like dvbsnoop to explore the
streams. The VBI data is encoded into the "picture" of an analog signal.

If ivtv, there's a tool that comes with the package (see the README's
and ). If a framegrabber, there are many other tools. If you're trying
to see VBI data from a digital TV recording in Myth, using
mythfrontend's -v vbi option may be the easiest way.
