I'm looking for a/some simple circuits for decoding closed caption info from
the `dark area' of the video image which is generally available from video
signals.  Pointer to articles in generally available magazines/books would
be probably be best.  Detailed descriptions of the video signal helpful too
(do SMPTE reference books exist & have this?).

Where's the best place for an enterprising video experimenter to start from?
The best thing would be the video equivalent of radio's ``ARRL handbook''.

How about companies that sell simple kits to get one started in such things?

Cheap, education video effect boxes would be fun too---something like
inverting color signals (i'm easily amused).  Time to take apart the set...

Please send mail; I'll summarize if there's enough interest.
