recorded in Dolby Digital Surround EX.
With this additional channel you will
experience improved dynamics and a better
sensation of movement within the sound
fi eld. If media sources recorded in Dolby
Digital EX are decoded with a Digital EX
decoder, the format is detected
automatically, and the Dolby Digital EX
mode is selected. However, some media
sources recorded in Dolby Digital EX can
be detected as simple Dolby Digital media
sources. In this case Dolby Digital EX should
be selected manually.
DTS Digital Surround Modes
The following are further descriptions about the
DTS surround modes.
[DTS-HD Master Audio]
•
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™ (Expanded Surround)]
•
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
EN
22
– DTS-HD
– This
"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]
•
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, 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]
•
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.
