DTS
DTS has been adopted as a sound recording format in the latest movie theaters since the release of “JURASSIC PARK”
in 1993, and has a good reputation for high quality sound and dynamic surround effects.
In this system, 6 channels of digital sound are recorded on CD-ROM, rather than on the film. DTS adopts a
simultaneous playback format. With a low rate of compression of sound signals and a high rate of transmittance, a
higher sound quality format is produced. Also, unlike the process of recording digital sounds on film directly, the only
components required are a CD-ROM player as might be used with a personal computer and a DTS processor, and
therefore less investment is required than with other formats. For this reason, the format is being introduced in more
and more movie theaters, and is being adopted in home movie software (DVD, LD) and music software (5.1 channel
CD).
More than 11,000 movie theaters around the world have adopted the DTS format, which is now the most popular digital
format for movie theaters, especially in U.S.A, Europe, and Asia.
