7.	THX ®	1982	2-6	Either					Theaters, DVD, LD, VHS

Note 1 - All formats require decoders, except Stereo and THX. THX is not a processing system but an audio/video quality control approval system. Its certification stamp means that the video and audio quality at theaters and CD/DVD discs meet uniform standards. This means the same movie viewed at one theater will not be different when viewing it at another theater.

Note 2 - Data rate = bits sampled X sample rate. A CD player (44.1kHz) rate was chosen for comparison. The DVD sample rate of 48kHz would make its data rate higher than shown.

Note 3 - LD = Laser Discs; DVD = Digital videodiscs; DTV = Digital TV; theaters = Movie theaters; VHS = Videotape format.
