How is 'closed-captioning' transmitted in the video signal?

Are there any devices that can read closed-captioned text
and output ASCII?

I didn't think this was easy, but I recently read the following
in "The Media Lab, Inventing the Future at MIT", by Stewart Brand:

  "The Lab already has a working program called NewsPrint that every
   night prints out the closed-captioned text of the 'ABC Evening News'
   along with images it's taken off the air for illustration."

Any information or pointers to information about this will be
appreciated.
