The Cyndustries List

I actually built analog video synthesizers while working with David 
Jones at the Experimental TV Center in the seventies.

See the two yellow boxes with black knobs in the upper right of the 
photo of David?  It is an analog synthesizer I built  for the ETC.  I am 
mentioned on the site, but they don't know what I did really.  It says 
something about a video switcher.  I do remember building a video matrix 
switcher (8 inputs routed to any of 8 outputs I think).  But I don't 
remember the details.

Analog video requires a 10Mhz bandwidth.  In those days it had to be all 
discrete transistors.  Now days, I imagine there are high slew rate op 
amps that could handle video.  For high quality you would want 
multi-layer PC boards.  Shielding is a much bigger concern; you use a 
lot of coax internally.  The standard connector is a BNC jack.  One of 
the things David and I worked on was interfacing audio and video 
synthesizers.  David's voltage controlled video mixers, keyers, and 
colorizers could be controlled by LFO's, Envelope Generators, and so forth.

We had a limited budget, so the quality of the signal suffered in some 
of the prototypes (bleed-through, and video sent through scratchy 
pots).  David kept improving his designs and had his own business 
later.  Seems he still has it.
