ENGLISH
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.
• dts Neo:6
®
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.
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 fi ve
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 fi ve- or six-channel
layout, in a way which does not diminish the subtlety
and integrity of the original stereo recording.
• dts Digital Surround ES
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.

• dts Digital Surround 96/24
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 fi lters 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.
DTS-HD Master Audio is capable of delivering audio
that is a bit-for-bit identical to the studio master.
DTS-HD Master Audio delivers audio at super high
variable bit rates -24.5 mega-bits per second (Mbps)
on Blu-ray discs and 18.0 Mbps on HD-DVD - that
are signifi cantly higher than standard DVDs . This bit
stream is so "fast" and the transfer rate is so "high"
that it can deliver the Holy Grail of audio: 7.1 audio
channels at 96k sampling frequency/24 bit depths
that are identical to the original. With DTS-HD Master
Audio, you will be able to experience movies and
music, exactly as the artist intended: clear, pure, and
uncompromised.
