You are correct in saying that shutter glasses are used to view
field-sequential 3D video on TV monitors.  In addition to the shutter
glasses you alse require a little black box (a glasses driver/synchroniser
box).  The Crystaleyes glasses are probably the most expensive Liquid
Crystal Shutter glasses available but are much more complicated than
you would need just for viewing 3D video on TV monitors.  They also
do not have the little black box for synchronising the glasses
with NTSC field-sequential 3D video.  

There are several LCD shutter glasses products available on the
market.  Below is a listing.  Most of them, however, are aimed at the
3D PC market (i.e. 3D on your computer screen) and some cannot
be used to view 3D video out of the box.

Of the above products, the only products which provide both the glasses
and the glasses driver/synchroniser for NTSC 3D video are
(i) 3DTV Corp 3D-Theatre (ii) 3D TV Corp PC-3D-TV and (iii) VREX VR-Surfer.
The VREX product isn't quite to market yet, but I am told it will
be available soon.

I have been thinking about releasing details of the glasses 
driver/synchroniser box which I designed and have been using in my work
for some time but (i) I haven't got around to it and (ii) I still
have dreams of making lots of money out of it.  ;-)

The 3DTV and VREX products are what you are looking for.
I have not heard the term "analogic" before.  The term "field-sequential"
is what is usually used to describe this technique.  Where/who is using
the term "analogic"?

Regards,
Andrew.
