Just to keep the record straight,

SQ was the CBS/Sony system, originally developed by Peter Scheiber, and
further developed
by Ben Bauer at CBS labs, along with Sony.

QS was the system developed by Sansui in Japan.

As I have pointed out, in another post, in the late 70s early 80s Dolby
bought rights
to the CBS and Sansui patents. That's called covering your posterior
(against potential
patent suits).

But you're right, Brian the Dolby stuff is mostly based on QS. I'm told.

Actually I thought all the hi-fi tweeks - you know the type that buy signal
cables that cost $700 per meter - they prefer DTS to Dolby Digital because
of the less severe data rate reduction used.
