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 Surround format, DTS-ES Extended
Surround gready improves the 3BO-degree surround impression and space expression thanks to fur[her expanded
surround signals This format has been used professionally in movie theaters since 1999
In addition to the 51 surround channels (FL, FR, C, SL, SR and LFE), DTS-ES Extended Surround also offers the
SB (Sunound Back, sometimes also referred to as "surround center") channel for sunound playback with a total
of 61 channeJs DTS-ES Extended Surround includes two signal formats with different surround signal recording
methods, as described below
• DTS-ES
TM
Discrete 6.1
DTS-ESTM Discrete 61 is the newest recording format With it, all 61 channeJs (including the SB channel)
are recorded independently using a digital discrete system The main feature of this format is that because
the SL, SR and SB channels are fully independent, the sound can be designed with total freedom and it is
possible to achieve a sense that the acoustic images are moving about freely among the background sounds
surrounding the listener from 360 degrees
Though maximum per[ormance is achieved when sound tracks recorded with this system are played using
a DTS-ES decode_, when played with a conventional DTS decoder the SB channel signals are automatically
down-mixed to the SL and SR channels, so none of the signal components are lost
• 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 beforehand Upon playback they are decoded to the SL, SR and SB channels The performance
of the encoder used at the time of recording can be fully matched using a high precision digital matrix
decoder developed by DTS, thereby achieving surround sound more faithful to the producer's sound design
aims than with conventional 51- or 6 1-channel systems
In addition, the bit stream format is 100% compatible with conventional DTS signals, so the effect of the
Matrix 6I format can be achieved even with 5 t-channel signal sources Of course it is also possible to play
DTSES Matrix 61 encoded sources with a DTS 5 1-channel decoder
When DTS-ES Discrete 61 or Matrix 6I encoded sources are decoded with a DTS-ES decoder, the format
is automatically detected upon decoding and the optimum playing mode is selected However, some Matrix
61 sources may be detected as having a 5 t-channel format, so the DTSES Matrix 61 mode must be set
manually to play these sources
(For instructions on selecting the surround mode, see page 301
The DTS-ES decoder includes another function, the DTS Neo:6 surround mode for 6 1-channel playback of
digital PCM and analog signal sources
• DTS Neo:6 TMsurround
This mode applies conventional 2-channel signals to the high precision digital matrix decoder used for DTS-
ES Matrix 61 to achieve 6 1-cbannel surround playback¸ High precision input signal detection and matrix
processing enable full band reproduction (frequency response of 20 Hz to 20 kHz or greater) for all 6I
channels, and separation between the different channels is _mproved to the same level as that of a digital
discrete system¸
DTS Neo:6 surround includes two modes for selecting the optimum decoding for the signal source¸
• DTS Neo:6 Cinema
This mode is optimum for playing movies Decoding is per[ormed with emphasis on separation
performance to achieve the same atmosphere with g-channel sources as with 6 1-channel sources
This mode is effective for playing sources recorded in conventional surround formats as well, because the
in-phase component is assigned mainly to the center channel (C) and the reversed phase component to
the surround (SL, SR and SB channels)
• DTS Nee:6 Music
This mode is suited mainly for playing music Changes in the sound qualify are reduced by decoding with
emphasis on the front channel signals {FL and FRI, and a natural sense of expansion _s g_ven to the sound
field by the effect of the surround signals output from the center (C) and surround (SL, SR and SB)
channels
The sampling frequency, number of bits and number of channels used for recording of music, etc, in studios has
been increasing in recent years, and there are a growing number of high quality signal sources, including 96
kHd24 bit 5 1-channel sources
For example, there are high picture/sound quality DVD video sources 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 possible with DVD audio sources, but DVD audio players are
required to play them with this high quality
DTS 96/24 is a multi-channel digital signal format developed by Digital Theater Systems Inc in order to deal with
this situation
Conventional surround formats used sampling frequencies of 48 or 44 1 kHz, so 20 kHz was about the maximum
playback signal frequency With DTS 96/24, the sampling frequency is increased to 96 or 882 kHz to achieve a
wide frequency _ange of over 40 kHz
In addition, DTS 96/24 has a resolution of 24 bits, resulting in the same frequency band and dynamic lange as 96
kHd24 bit PCM
As with conventional DTS Surround, DTS 96/24 is compatible with a maximum of 51 channels, so sources
recorded using DTS 96/24 can be played in high sampling frequency, multiple channel audio with such normal
media as DVD videos and CDs
Thus, with DTS 96/24, the same 96 kHz/24 bit muki-channel surround sound as with DVD-Audio can be achieved
while viewing DVD-Video images on a conventional DVD-Video player {_11 Furthermore, with DTS 96/24
compatible CDs, 882 kHz/24 bit multi-channel surround can be achieved using normal CD/LD players ( _ 1 )
Even with the high quality multFchannel signals, the recording time is the same as with conventional DTS
surround sources
What's more, DTS 96/24 is fully compatible with the conventional DTS surround format, so DTS 96/24 signal
sources can be played with a sampling frequency of 48 kHz or 441 kHz on conventional DTS or DTS-ES surround
decoders ( ÷ 2)
1 : A DVD player with DTS digital output capabilities (for CD/LD players, a player with digital outputs for
conventional DTS CDs/LDs) and a disc recorded in DTS 96/24 are required
2: The resolution is 24 or 20 bits, depending on the decoder
