DTS: Digital Theater Systems. In cinemas, DTS is a multichannel audio source for synchronized film sound. A modified SMPTE time code is optically imaged on the film itself, and the DTS processor uses this to synchronize the soundtrack audio which is recorded in a compressed form on standard CD-ROM media. The timecode modifications allow identifying data that ensures that a certain film's soundtrack will only run with that film. Release-current "trailer" soundtracks are also recorded on most film DTS disks and also on separate trailer-only disks. DTS processors can hold 2 or 3 CDs to allow for 2-disk soundtracks and/or trailer disks. DTS uses a lighter compression scheme than Dolby Digital for audio.
DTS was first shown in the cinema with the release of Jurassic Park in 1993.
- DTS is also a sound format available on some DVDs. This system uses a similar compression algorithm but does not require separate DTS CD-ROM media.
