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. -todd-- internet: toad@cs.cmu.edu us snail: Pobox 81795-UN, Pittsburgh PA 15217 (mail-art exchange) ``In Xanadu, to be an individual one must be a clone.'' -future proverb --
