| Dolby Surround Sound existed in home receivers before Dolby Pro Logic.
| Pro Logic was an improvement over "plain" Dolby Surround. It added
| steering logic to help direct the sounds to the proper speakers.
Right. I think what I meant to say is that home Dolby Surround is two
channels (left and right with mono rear) while theater Dolby Surround is
three channels (left, right with mono rear and center channel steering).
When three channel Dolby Surround was added to home receivers they renamed
it "Pro Logic" to avoid confusion with two channel Dolby Surround.
| Now Dolby Digital is a discrete set up while Dolby Surround and it's
| enhanced version, Pro Logic were matrixed kind of similar to SQ
| quadraphonic sound.
Exactly. The trick is to use phase inversion to matrix multiple audio
tracks together. Which sounds (heh) like it shouldn't work, but it does
when done right. When done wrong -- like on the Japanese audio for the DVD
box set of "The Slayers" -- it screws up everything.
