DTS is essentially a modern day incarnation of the Vitaphone "sound on disc" system, it uses a timecode, read by a timecode reader on the projector, to sync with a CD-Rom (or DVD) which is encoded with six channels: Left, Center, Right, Right Surround, Left Surround, and Low-Frequency Effects/Subwoofer. 70mm versions may have a different channel layout, most commonly "Special Venue" (Left, Left Extra, Center, Right, Right-Extra, and Surround)
Unlike Dolby Digital and other optical soundtracks, DTS does not usually suffer from wear incurred from careless print handling (unless, for example, there is an emulsion scratch directly on the timecode), instead, DTS fails because of scratched or otherwise damaged DTS discs. More often, a print will arrive without any DTS disks. If you have a print with DTS discs, it is recommended that you do a test screening to make sure they will play back flawlessly.
DTS is the only sound format used in modern 70mm prints. It is CRUCIAL that full run-throughs of 70mm prints with DTS tracks be done as there is no analog backup.
Many collectors and archives treat original DTS discs with extreme care and do not use them for projection purposes. Instead, they make copies of the discs and use those, usually also saving them as ISO files and migrating them from time to time. This way, the original discs are handled as little as possible.
The first film released in DTS was JURASSIC PARK (1993)
