DTS was introduced in 1994 to provide 5.1 channels of
discrete digital audio into home theater systems.
DTS brings you premium quality discrete multi-channel
digital 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
channel 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.
Neo6 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-
theater 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
presentation.
< Neo 6 offers a music mode to expand stereo nonmatrix
recordings into the five-or six-chnnel 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 Surroud format, DTS-ES Extended Surround
greatly improves the 360-degree surround impression and
space expression thanks to further expanded surround
signals. This format has been used professionally in movie
theaters 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.

Dolby Digital identifies the use of Dolby Digital (AC-3) audio
coding for such consumer formats as DVD and DTV. As with
film sound, Dolby Digital can provide up to five full-range
channels for left, center, and right screen channels,
independent left and right surround channels, and a sixth (
".1") channel for low-frequency effects.
Dolby Surround Pro Logic II is an improved matrix decoding
technology that provides better spatiality and directionality
on Dolby Surround program material; provides a convincing
three-dimensional soundfield on conventional stereo music
recordings; and is ideally suited to bring the surround
experience to automotive sound. While conventional
surround programming is fully compatible with Dolby
Surround Pro Logic II decoders, soundtracks will be able to
be encoded specifically to take full advantage of Pro-Logic
II playback, including separate left and right surround
channels. (Such material is also compatible with
conventional Pro Logic decoders. )
Dolby Digital EX creates six full-bandwidth output channels
from 5.1-channel sources. This is done using a matrix
decoder that derives three surround channels from the two
in the original recording. For best results, Dolby Digital EX
should be used with movies soundtracks recorded with
Dolby Digital Surround EX.
