Before I begin, let me give you a primer on the two technologies promoted at the event. First and foremost was Dolby's Surround 7.1 implementation. Right now, the standard is 5.1 which features a left, right, and center speaker in the front, a left and right speaker in the back, and the .1 is the subwoofer or bass channel. The new 7.1 setup is a left, right, and center speaker in the front, a left and right speaker on the direct left and right, a left and right speaker on the back wall, and a .1 subwoofer channel. The general principle is that the more channels you have, the more immersive a sound-scape or audio environment you can create.
Dolby's new glasses are made by 3M and include a security device to stop forgetfulness in its tracks. More importantly, now that the lenses are made with plastic film rather than glass, each pair of Dolby 3D glasses is only $12 a piece, and not $50. That is a definite plus for nervous exhibitors worried about losing money from accidental theft.
