Description
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.
