DTS was introduced in 1994 to provide 5.1 channels of dis- crete digital audio into home theater systems.
DTS brings you premium quality discrete multi-channel digi- tal sound to both movies and music.
DTS is a multi-channel sound system designed to create full range digital sound reproduction.
The no compromise DTS digital process sets the standard of quality for cinema sound by delivering an exact copy
of the studio master recordings to neighborhood and home theaters.
Now,every moviegoer can hear the sound exactly as the moviemaker intended.
DTS can be enjoyed in the home for either movies or music on of DVD's, LD's, and CD's.

The advantages of discrete multichannel systems over matrix are well known.
But even in homes equipped for discrete multichannel, there remains a need for high-quality matrix decoding. This is because of the large library of matrix surround motion pictures available on disc and on VHS tape; and analog television broadcasts.
The typical matrix decoder of today derives a center chan- nel and a mono surround channel from two-channel matrix stereo material. It is better than a simple matrix in that it includes steering logic to improve separation, but because of its mono, band-limited surround it can be disappointing to users accustomed to discrete multichannel.
Neo:6 offers several important improvements as follow.
<Neo:6 provides up to six full-band channels of matrix decoding from stereo matrix material. Users with 6.1 and 5.1 systems will derive six and five separate channels, respectively. corresponding to the standard home-the- ater speaker layouts.
<Neo:6 technology allows various sound elements within a channel or channels to be steered separately, and in a way which follows naturally from the original presenta- tion.
<Neo:6 offers a music mode to expand stereo nonmatrix recordings into the five-or six-channel layout, in a way which does not diminish the subtlety and integrity of the original stereo recording.
DTS-ES Extended Surround is a new multi-channel digital signal format developed by Digital Theater Systems Inc. While offering high compatibility with the conventional DTS Digital Surround format, DTS-ES Extended Surround greatly improves the 360-degree surround impression and space expression thanks to further expanded surround sig- nals. This format has been used professionally in movie the- aters since 1999.
In addition to the 5.1surround channels (FL, FR, C, SL, SR and LFE), DTS-ES Extended Surround also offers the SB (Surround Back) channel for surround playback with a total of 6.1 channels. DTS-ES Extended Surround includes two signal formats with different surround signal recording methods, as DTS-ES Discrete 6.1 and DTS-ES Matrix 6.1.

The stereo CD is a 16-bit medium with sampling at 44.1 kHz. Professional audio has been 20- or 24- bit for some time, and there is increasing interest in higher sampling rates both for recording and for delivery into the home. Greater bit depths provide extended dynamic range. Higher sam- pling rates allow wider frequency response and the use of anti-alias and reconstruction filters with more favorable aural characteristics.
DTS 96/24 allows for 5.1channel sound tracks to be encod- ed at a rate of 96kHz/24bits on DVD Video titles.
When DVD-video appeared, it became possible to deliver 24-bit, 96 kHz audio into the home, but only in two channels, and with serious limitations on picture. This capability has had little use.
DVD-audio allows 96/24 in six channels, but a new player is needed, and only analog outputs are provided, necessitat- ing the use of the D/A converters, and analog electronics provided in the player.
DTS 96/24 offers the following:
1.Sound quality transparent to the original 96/24 master.
2.Full backward compatibility with all existing decoders. (Existing decoders will output a 48 kHz signal)
3.No new player required: DTS 96/24 can be carried on DVD-video, or in the video zone of DVD-audio, accessible to all DVD players.
4.96/24 5.1-channel sound with full-quality full motion video, for music programs and motion picture soundtracks on DVD-video.
