What does DTS Digital Sound® do for cinemas?
The DTS Digital Sound process for motion pictures is designed for the digital sound release of motion pictures in 6-track theaters. It also allows playback of videos for “pre-show” such as commercials. The playback of digital sound is a dual system where the digital audio data is recorded on CD-ROM discs. A proprietary DTS timecode is printed on the motion picture print along with a conventional stereo optical soundtrack. The timecode is used by the DTS system to synchronize the sound and picture. The timecode lies between the picture and optical sound track, and is printed onto the release print from the soundtrack negative. There is a single inventory of prints. The DTS system provides left, center, right, split surrounds (or mono surround) and subwoofer channels. The DTS system is completely automatic and fail-safe in operation requiring no action by the projectionist. DTS automatically starts and stops, and tracks film breaks and changeovers. The digital audio data is sampled at 44
