It depends what you want from the closed captioning. If you are happy just
to overlay the video with captions, you can serve it all up as a single
video signal - no problem there. If you want to make it work as a separate
data stream, the real problem is to provide a setup where the text data
stream can be continuously refreshed. Should still be possible, but I am
not sure of the techniques - I'll sleep on it.

  As i understand it, you cannot have simultaneous close captioning on a LIVE webcast over the internet as you can on television.  basically the technology is not there yet.  
  To get the close captioning you need to take the video after it is over and use something like Adobe premiere to add the close captioning.
  Is this correct?
