• 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

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

decoders, soundtracks will be able to be encoded

specifically to take full advantage of Pro Logic

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.

About Dolby Pro Logic

IIx

Dolby Pro Logic IIx technology delivers a natural

and immersing 7.1-channel listening experience to

the home theater environment. A product of

Dolby's expertise in surround sound and matrix

decoding technologies, Dolby Pro Logic II x is a

complete surround sound solution that maximizes

the entertainment experience from stereo as well

as 5.1-channel encoded sources.

DESCRIPTION

DTS was introduced in 1994 to provide 5.1

channels of discrete digital audio into home theater

systems.

DTS brings you premium quality discrete

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.

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 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.

Dolby Pro Logic IIx is fully compatible with Dolby

Surround Pro Logic technology and can optimally

decode the thousands of commercially available

Dolby Surround encoded video cassettes and

television programs with enhanced depth and

spatiality. It can also process any high-quality

stereo or Advanced Resolution 5.1-channel music

content into a seamless 6.1- or 7.1-channel

listening experience.

Circle Surround II (CS-II) is a powerful and

versatile multichannel technology. CS-II is

designed to enable up to 6.1 multichannel surround

sound playback from mono, stereo, CS encoded

sources and other matrix encoded sources. In all

cases the decoder extends it into 6 channels of

surround audio and a LFE/subwoofer signal. The

CS-II decoder creates a listening environment that

places the listener “inside” music performances

and dramatically improves both hi-fi audio

conventional surround-encoded video material.

CS-II provides composite stereo rear channels to

greatly improve separation and image positioning –

adding a heightened sense of realism to both audio

and A/V productions.

CS-II is packed with other useful feature like dialog

clarity (SRS Dialog) for movies and cinema-like

bass enrichment (TruBass). CS-II can enable the

dialog to become clearer and more discernable in

movies and it enables the bass frequencies

contained in the original programming to more

closely achieve low frequencies – overcoming the

low frequency limitations of the speakers by full

octave.
