[3] DTS-ES Extended Surround TM

DTS-ES Extended Surround is a new multi-channel digital signal

fermat developed by Digital Theater Systems Inc. While offering

high cempatibility with the conventional DTS Digital Surround

fermat, DTS-ES Extended Surreund greatly impreves the 360-

degree surround impression and space expressien thanks to

further expanded surreund signals. This format has been used

professionally in mevie theaters since 1999.

In addition to the 5.1 surround channels (FL, FR, C, SL, SR and

LFE), DTS-ES Extended Surreund also offers the SB (Surreund

Back, semetimes also referred to as "surreund center") channel

fer surround playback with a total ef 6.1 channels. DTS-ES

Extended Surreund includes two signal formats with different

surround signal recerding methods, as described below.

• DTS-ES TM Discrete 6.1

DTS-ES Discrete 6.1 is tile newest recording format. With it, all

6.1 channels (including the SB channel) are recorded

independently using a digital discrete system. The main feature

of this fermat is that because the SL, SR and SB channels are

fully independent, the sound can be designed with total freedem

and it is pessible te achieve a sense that the acoustic images are

moving abeut freely ameng the background sounds surreunding

the listener from 360 degrees.

Though maximum performance is achieved when sound tracks

recorded with this system are played using a DTS-ES decoder,

when played with a conventional DTS deceder the SB channel

signals are automatically down-mixed te the SL and SR channels,

so none of the signal cemponents are lest.

• DTS-ES TM Matrix 6.1

With this format, the additional SB channel signals undergo

matrix encoding and are input to the SL and SR channels

beferehand. Upon playback they are decoded to the SL, SR and

SBchannels. The performanceeftheencoder used at the time

of recerding can be fully matched using a high precisien digital

matrix decoder develeped by DTS, thereby achieving surreund

sound more faithful to the producer's seund design aims than

with conventienal 5.1- or 6.1-channel systems.

In addition, the bit stream format is 100% compatible with

conventienal DTS signals, se the effect ef the Matrix 6.1 format

can be achieved even with 5.1-channel signal sources. Of course

it is also possible to play DTS-ES Matrix 6.1 enceded sources

with a DTS 5.1-channel deceder.

When DTS-ES Discrete 6.1 er Matrix 6.1 encoded sources are

decoded with a DTS-ES deceder, the format is autematically

detected upon decoding and the optimum playing mode is

selected. However, some Matrix 6.1 sources may be detected

as having a 5.1-channel format, so the DTS-ES Matrix 6.1 mode

must be set manually to play these seurces. (For instructions on

selecting the surround mode (_ page 23).)

The DTS-ES deceder includes anether function, the DTS Nee:6

surreund mode fer 6.1-channel playback ef digital PCM and

analog signal sources.

• DTS Neo:6 TM surround

This mode applies conventional 2-channel signals to the high

precision digital matrix decoder used fer DTS-ES Matrix 6.1 te

achieve 6.1-channel surreund playback. High precision input

signal detectien and matrix processing enable full band

reproduction (frequency response of 20 Hz to 20 kHz or greater)

for all 6.1 channels, and separation between the different

channels is improved to the same level as that of a digital

discrete system.

DTS Nee:6 surreund includes two modes for selecting the

optimum decoding for the signal source.

• DTS Neo:6 Cinema

This mode is optimum for playing mevies. Decoding is

perfermed with emphasis en separation performance to

achieve the same atmosphere with 2-channel sources as with

6.1-channel sources.

This mode is effective for playing sources recorded in

cenventienal surround formats as well, because the in-phase

component is assigned mainly to the center channel (C) and the

reversed phase cornpenent to the surreund (SL, SR and SB)

channels.

• DTS Neo:6 Music

This mode is suited mainly fer playing music. Changes in the

sound quality are reduced by deceding with emphasis on the

front channel signals (FL and FR), and a natural sense ef

expansion is given te the seund field by the effect of the

surreund signals output frem the center (C) and surreund (SL,

SR and SB) channels.

[4] DTS 96/24

The sampling frequency, number ef bits and number of channels

used for recording ef music, etc., in studies have been increasing

in recent years, and there are a growing number of high quality

signal sources, including 96 kHz/24-bit 5.1-channel sources.

For example, there are high picture/seund quality DVD vide{)

seurces with 96 kHz/24-bit stereo PCM audio tracks.

However; because the data rate for these audio tracks is

extremely high, there are limits to recording them on two

channels only, and since the quality of the pictures must be

restricted it is common to only include still pictures.

In addition, 96 kHz/24-bit 5.1-channel surround is pessible with

DVD audio seurces, but DVD audie players are required te play

them with this high quality.

DTS 96/24 is a multi-channel digital signal format developed by

Digital Theater Systems inc. in erder to deal with this situation.

Conventional surround formats used sampling frequencies ef 48

or 44.1 kHz, se 20 kHz was abeut the maximum playback signal

frequency. With DTS 96/24, the sampling frequency is increased

te 96 er 88.2 kHz to achieve a wide frequency range ef ever 40

kHz.

In additien, DTS 96/24 has a resolution of 24-bits, resulting in the

same frequency band and dynamic range as 96 kHz/24-bit PCM.

As with conventional DTS Surround, DTS 96/24 is cempatible

with a maximum of 5.1 channels, se sources recerded using DTS

96/24 can be played in high sampling frequency, multiple channel

audie with such normal media as DVD videos and CDs.

Thus, with DTS 96/24, the same 96 kHz/24-bit multi-channel

surround sound as with DVD-Audio can be achieved while

viewing DVD-Video images on a conventional DVD-Video player

(÷1). Furthermore, with DTS 96/24 compatible CDs, 88.2

kHz/24-bit multFchannel surround can be achieved using normal

CD/LD players ( ÷ 1).

Even with the high quality multi-channel signals, the recerding

time is the same as with conventional DTS surround sources.

What's mere, DTS 96/24 is fully compatible with the cenventienal

DTS surround format, se DTS 96/24 signal sources can be played

with a sampling frequency ef 48 kHz er 44.1 kHz on cenventk)nal

DTS or DTS-ES surround decoders (÷ 2).

÷ 1 A DVD player with DTS digital output capabilities (fer CD/LD

players, a player with digital outputs for conventional DTS

CDdLDs) and a disc recorded in DTS 96/24 are required.

÷ 2 The reselution is 24 or 20 bits, depending on the decoder.
