Hi,
   Please help me!

   I am trying to find information on "Deep Vision" technology, by James
Ashbey of England. I have tried the patent catalogs, various databases,
English newspapers etc.. Obviously, I have not read ALL English papers
(yet) and will continue to visit the school library. However, I am
getting extremely frustrated, so please forgive me if this is not the
correct place to post.

   Here are some excerpts from an article that appeared in an AP article
on June 3, 1990 (the only reference to this technology I have seen).



   LONDON - An inventor says he has developed three-dimensional television...
   ...James Ashbey, 33, the British inventor.....The technology does not
   require special glasses or screens. It can convert all new and existing
   black and white and color films into 3-D, along with live broadcasts...
   says his company, Delta Group.

   {about presentation..}...the effect appears three dimensional, but it loses
   some resolution ... and is very blurry. .....has applied for an
   international patent {{I didn't know there was such a thing - I assume
   he means he applied in many countries}}, which he calls "Deep Vision."

   ...financial support from RCA-Columbia Pictures Int. ... and Brent Walker
   Holdings PLC, ...

   ...The technology takes a normal film, makes a digital version and inserts
   ... stereo cues. A digital decoder added to an ordinary television set then
   uses these cues to send slightly different images to each eye...


WOW! sounds pretty amazing. Acually, amazing enough that I am tempted to
dismiss it as a bunch of crock :-), except that it has the name RCA attached
and also because there was a display, not just a news release.

I cannot see how an ordinary TV can send different images to each eye without
special glasses - of course something could have been lost in the reporter's
translation (from inventers words to news report).

However, I would like to know more about this, so if anyone has any info
please please let me know. I have tried poring through British Newspapers
but could not find any info. If you can even think of somewhere I could
look I would appreciate it -however phone calls to London would be beyond
my student budget :-(.

    Please e-mail, unless it seems to be of general interest (I guess
information would be of general interest and suggestions of places to
look would not :-).

         Thank you very much for any help you can give,
