DTS SURROUND MODES
The following are further descriptions about the DTS surround modes.
DTS-HD MASTER AUDIO
DTS-HD Master Audio is a technology that delivers master audio sources
recorded in a professional studio to listeners without any loss of data,
preserving audio quality. DTS-HD Master Audio adopts variable data
transfer rates, facilitating data transfer to the maximum rate of 24.5 Mbps
in the Blu-ray disc format, 18.0 Mbps in the HD-DVD format, which by
far exceeds that of a standard DVD. These high data transfer rates enable
lossless transmission of 96 kHz/24-bit 7.1-channel audio sources without
deteriorating the quality of the original sound. DTS-HD Master Audio is an
irreplaceable technology that can reproduce sound faithfully as intended
by the creator of music or movies.
DTS - ES EXTENDED SURROUND ™ (DTS ES)
This is a new multi-channel digital format which greatly improves the 360°
spatial sensation of the Surround impression thanks to the greater space
expansion of the surround signals, providing high compatibility with the
conventional DTS format.
In addition to the 5.1 channels, the expanded DTS-ES Surround also
offers the back surround (also sometimes called the “surround centre”)
in reproduction, providing a total of 6.1 channels. The expanded DTS-ES
Surround includes two formats, with two different methods of surround
signal recording, as follows:
DTS-ES™ DISCRETE 6.1
Since the signals of the 6.1 Surround channels (including the back channel)
are completely independent, it is possible to achieve the sensation that the
acoustic image is moving about freely among the background sounds, 360
degrees surrounding the listener.
Although maximum quality is achieved with sound tracks recorded using
this system and reproduced using the DTS-ES decoder, when played with
a conventional DTS decoder, the back surround channel is automatically
downmixed in the surround right and surround left channels of the
surround system, in such a way that none of the signal components are
lost.
DTS - ES™ MATRIX 6.1
In this format, the additional signals of the back channel receive a matrix
encoding and are inputted into the right and left surround channels.
During reproduction they are decoded to the right, left and back surround
channels.
Since this bit-stream format is 100% compatible with conventional DTS
signals, the DTS-ES Matrix 6.1 format effect can also be achieved from
sources with DTS-ES 5.1 signals.
Naturally, it is also possible to reproduce from a DTS 5.1 channel decoder,
signals recorded in DTS-ES 6.1.
When a DTS-ES decoder processes a discrete DTS-ES 6.1 or in Matrix 6.1,
these formats are automatically detected and the Optimum Surround
mode is selected. However, some DTS-ES Matrix 6.1 sources may be
detected as DTS. In this case the DTS-ES Matrix mode should be selected
manually in order to reproduce them.
DTS NEO: 6™ SURROUND
This mode applies the conventional 2-channel signals such as digital PCM
or analog stereo signals to the high precision digital matrix decoder used
for DTS-ES Matrix 6.1 to achieve 6.1-channel surround playback. DTS Neo: 6
surround includes two modes for selecting the optimum decoding of the
signal sources:
DTS NEO: 6 CINEMA :
This method is ideal for the reproduction of
movies. The decoding takes place by emphasizing the separation in
order to achieve the same atmosphere with 2-channel, as with 6.1-
channel sources.
DTS NEO: 6 MUSIC :
Mainly recommended for music reproduction.
The right and left front channels do not pass through the decoder and
are reproduced directly so there is no loss in sound quality, and the
effects of the right surround, left surround, central and back surround
channels add a natural sensation of expansion of the sound field.
