The ivtv driver uses its own format to store CC data. Theoretically it might
be possible to adapt the driver to support this standard, but that's a
non-trivial exercise.
But using the ivtv format it is possible to record and output CC data
correctly. At least, I think that that's the current status of the driver
(being in PAL country I cannot verify it myself).
The document doc/README.vbi contains more background information on the whole
VBI topic.
