• 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 multichannel
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
signals. This format has been used professionally
in movie theaters since 1999.
In addition to the 5.1 surround 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 sampling 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 encoded 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, necessitating 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.
Dolby Digital identifies the use of Dolby Digital
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
s o u n d f i e l d o n c o n v e n t i o n a l s t e r e o m u s i c
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.

DESCRIPTION
DTS was introduced in 1994 to provide 5.1
channels of discrete digital audio into home theater
systems.
D T S b r i n g s y o u p r e m i u m q u a l i t y d i s c r e t e
multichannel digital sound to both movies and
music.
DTS is a multichannel 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.
B u t e v e n i n h o m e s e q u i p p e d f o r d i s c r e t e
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.
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-theater
speaker layouts.
• N e o : 6 t e c h n o l o g y a l l o w s v a r i o u s s o u n d
elements within a channel or channels to be
steered separately, and in a way which follows
naturally from the original presentation.
