Audio formats/Decoding
Dolby
The Dolby technologies are explained below.
See http://www.dolby.com for more detailed
information.
Dolby Digital
Dolby Digital is a multichannel digital audio
coding system widely used in cinemas, and
in the home for DVD and digital broadcast
soundtracks.
Dolby TrueHD
Dolby TrueHD is the lossless encoding technol-
ogy developed for high-definition optical discs
in the upcoming era.
Dolby Digital Plus
Dolby Digital Plus is the audio technology for
all high-definition programming and media. It
combines the efficiency to meet future broad-
cast demands with the power and flexibility to
realize the full audio potential expected in the
upcoming high-definition era.
Dolby Digital Surround EX
Dolby Digital Surround EX (the EX stands for
EXtended) is an extension of Dolby Digital
encoding whereby a surround back channel
is matrixed into the surround left/right chan-
nels for 6.1 channel playback. This allows for
compatibility with Dolby Digital 5.1 channel
decoding, as well as for decoding using Dolby
Digital EX.
Dolby Pro Logic IIx and Dolby Surround
Dolby Pro Logic IIx is an improved version of the
Dolby Pro Logic II (and Dolby Pro Logic) decod-
ing system.
Dolby Surround is an encoding system which
embeds surround sound information within
a stereo soundtrack, which a Dolby Pro Logic
decoder can then use for enhanced surround
listening with greater sound detail.
Dolby Pro Logic IIz
Adding a pair of speakers above the front left
and right speakers adds expressiveness in the
vertical direction to the previous horizontally-
oriented sound field. The height channel
strengthens the sound field’s sense of three-
dimensionality and air, producing presence and
expansion.
DTS
The DTS technologies are explained below.
See http://www.dts.com for more detailed
information.
DTS Digital Surround
DTS Digital Surround is a 5.1-channel audio
coding system from DTS Inc. now widely used
for DVD-Video, DVD-Audio, 5.1 music discs,
digital broadcasts, and video games.
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 High Resolution Audio
A high definition audio technology by which
signals can be transferred over HDMI cables.
DTS-ES
DTS-ES (the ES stands for Extended Surround)
is a decoder that is capable of decoding both
DTS-ES Discrete 6.1 and DTS-ES Matrix 6.1
encoded sources.
DTS Neo:6
DTS Neo:6 can generate 7.1 channel surround
sound from any matrixed stereo source (such
as video or TV) and from 5.1 channel sources.
DTS Neural Surround
DTS Neural Surround can generate 7.1 chan-
nel surround sound from any matrixed stereo
source (such as video or TV).
THX
The THX technologies are explained below.
See http://www.thx.com for more detailed
information.
THX Cinema
A mode for playing in a home theater environ-
ment the sound tracks of theater movies that
have been recorded and edited for playback in
large spaces such as movie theaters.
THX Music
A mode adjusted mainly for listening to music
that has been masterized at a higher level than
movie sound tracks.
THX Games
A mode for playing the sound of games with
spatial fidelity. In many cases the sound is
mixed in the same way as for movies, but this
mode is meant for small environments rather
than the large environments of theaters.
THX Surround EX
A mode using technology developed jointly
by Dolby Laboratories and THX for creating a
sound field behind the listeners.
THX Loudness Plus
A mode creating a rich, subtle surround sound
field through optimal calibration of the volume
and frequency response of the individual chan-
nels according to the volume level.
Decoding
A technology for converting digital signals
that have been compressed upon recording
by a digital signal processing circuit, etc., into
the original signals. The term “decoding” (or
“matrix decoding”) is also used for the technol-
ogy which converts 2-channel sound sources
into multiple channels or expands 5.1-channel
signals into 6.1 or 7.1 channels.
Calibrating the sound field/
Improving the sound quality
Phase Control
The Phase Control technology incorporated into
this receiver’s design provides coherent sound
reproduction through the use of phase match-
ing for an optimal sound image at your listening
position.
Full Band Phase Control
The Full Band Phase Control feature calibrates
the frequency-phase characteristics of the
speakers connected.
Virtual Surround Back
When you’re not using surround back speakers,
selecting this mode allows you to hear a virtual
surround back channel through your surround
speakers. You can choose to listen to sources
with no surround back channel information.
Virtual Height
When you’re not using front height speak-
ers, selecting this mode allows you to hear a
virtual front height channel through your front
speakers.
Virtual Depth
When this mode is selected, the sound field
expands virtually to behind the display, result-
ing in a sound field with the same depth as
the 3D picture to achieve a better sense of
presence.
Auto Sound Retriever
The Auto Sound Retriever feature employs
DSP technology to restore sound pressure
and smooth jagged artifacts left over after
compression.
With some audio inputs, the Sound Retriever
effect is automatically optimized based on the
bitrate information of the contents that have
been input to achieve high sound quality.
