> An obvious method to this is observing the PDC signal
I agree, PDC would definitely be the best option.
This is the only thing I found on Google, and it's under the section
"2. Sliced VBI Data Interface
Proposal. This is not currently implemented in v4l2."
http://www.thedirks.org/v4l2/v4l2dsi.htm
(google cache: http://66.102.9.104/search?q=cache:E_XK7MrA3gkJ:www.thedirks.org/v4l2/v4l2dsi.htm+v4l2+pdc&hl=en )
So perhaps it's not possible yet? If there is an implementation, we need
to get it integrated into the record-server asap :)
