I searche frepatents online for "dolby sound digital projector" and
found this patent which would seem to support your view that the CCD
was two dimensional. Also searching google 1992 and CCD confirms CCD
od the order of 512K pixel were readily available at that time which
is clearly sufficient.

United States Patent 5710752
http://www.freepatentsonline.com/5710752.html
Abstract:     An apparatus recovers audio information from analog
and digital motion picture film soundtracks using a single optical
sensor that senses across the widths of both soundtracks. Symbols
representing audio information in the digital soundtrack are encoded
in two dimensions and are recovered by oversampling the symbols in two
dimensions. The two-dimensional encoding of digital information can be
used with a variety of recording media; however, in one embodiment,
the symbols are carried on motion picture film between the sprocket
holes.

**  Hmmm  -  so someone used the old  " drop of the  K "   trick  to
bamboozle everyone  ??







**  Hah  -   two dimensions  IS  better than one.

     Flat Earthers,  take heart.....

    That would explain everything!

Nothing stopping them using 4 CCDs to capture 4 audio
frames simultaneously. It's not as though very many pixels
are required in each one. They could even be optically
routed to a single CCD using prisms.
