Comment (by softworkz):

 > By the way, I believe the frame rate dependency of captions data is
 solely related to the time code that specifies which frame to embed the
 data in.  All that would be required to embed separate frame rates would
 be a calculation that would translate and align the two time codes without
 discarding data.  608 captions data simply acts on the frame it is
 embedded in not at a seperate specific time.

 The spec mandates a continuous (DTVCC) stream of data. It must not be
 on/off (sometimes there, sometimes not).
