Digital Theatre Sound.


(Digital Theater Sound) A family of digital audio encoding technologies used in movie theaters, home theaters and video games. Introduced in the movie "Jurassic Park" in 1993, the theater soundtrack is maintained on CD-ROMs that are synchronized with the film, making it compatible with existing theater systems (see image below).

DTS formats are not as compressed as Dolby Digital formats and therefore take up more space on the disc; however, many claim it to be the better quality. Following are the major DTS formats. See surround sound.

DTS Digital Surround (DTS) - 5.1 Channels
Five discrete channels of audio plus subwoofer (see surround sound).

DTS Extended Surround (DTS-ES) - 6.1 Channels
DTS-ES adds a rear center speaker in two ways. DTS-ES Discrete 6.1 uses a discrete center channel, whereas DTS-ES Matrix derives the channel from the other channels like Dolby Digital EX.

DTS Neo:6
Part of all DTS-ES decoders, Neo:6 creates six channels (5.1) from stereo sources. Resulting sound fills the room more than stereo, but not as good as true multi-channel formats. DTS Neo:PC provides the same capability for computers. See DTS UltraPC.

DTS 96/24
Boosts audio resolution on DVDs from 48/16 to 96/24. The 96/24 refers to 24-bit samples of the audio wave taken at 96 kHz rather than 16-bit samples at 48 kHz. Older DTS receivers will output a 48 kHz signal.

DTS-HD - High Resolution and Master Audio
Two high-definition DTS formats support 7.1 channels at 96/24 or stereo at 192/24 resolution. DTS-HD High Resolution Audio supports bit rates from 1.5 to 6 Mbps, while DTS-HD Master Audio supports up to 24.5 Mbps, sufficient to reproduce the original studio master bit for bit. DTS-HD formats are backward compatible and play on older DTS Digital Surround and EX equipment. DTS-HD and Dolby TrueHD are competing high-definition Blu-ray audio formats. HDMI 1.3 cables are required. See Blu-ray, Dolby Digital and HDMI.

Superseding DTS-HD and providing competition to Dolby Atmos (see Dolby Digital), DTS:X was introduced in 2015. Supporting 32 speaker locations, DTS:X works with any configuration in a hemispherical layout. Although height speakers are supported, they are not mandatory. Movie makers need only to create one version of their DTS:X sound track, which plays both in the cinema and home theaters.

DTS Headphone:X
A surround sound format for headphones. See DTS Headphone:X.

DTS Play-Fi
A streaming music protocol over Wi-Fi without data compression. See DTS Play-Fi.

The DTS Time Code
DTS is used with both 35 and 70mm movie projectors. This quad track 35mm film example shows the DTS time code that synchronizes the CD-ROM soundtrack. (Image provided under the Creative Commons Attribution ShareAlike 3.0 License, www.creativecommons.org/licenses/by-sa/3.0)
