Explanation of terms

A
Adobe RGB color / Adobe YCC601 color
Like x.v.Color, each of these color spaces defi nes
a palette of available colors that is larger than the
traditional RGB color model.
D
Deep Color
This technology allows expression of more number
of colors than the conventional 8 bits and can
reproduce colors close to natural ones without color
streak.
Dolby Digital
Dolby Digital is a multi-channel digital signal format
developed by Dolby Laboratories.
A total of 5.1 channels are played: 3 front channels
("FL" , "FR" and "C"), 2 surround channels
("SL" and "SR") and the "LFE" channel for low
frequencies.
Because of this, there is no crosstalk between
channels and a realistic sound fi eld with a "three-
dimensional" feeling (sense of distance, movement
and positioning) is achieved.
A realistic, powerful sense of presence is achieved
when playing movie sources in AV rooms as well.
Dolby Digital EX
Dolby Digital EX is a 6.1-channel surround format
proposed by Dolby Laboratories that allows users
to enjoy in their homes the "DOLBY DIGITAL
SURROUND EX" audio format jointly developed by
Dolby Laboratories and Lucas Films.
The 6.1 channels of sound, including surround back
channels, provide improved sound positioning and
expression of space.
Dolby Digital Plus
Dolby Digital Plus is an improved Dolby Digital signal
format that is compatible with up to 7.1 channels
of discrete digital sound and also improves sound
quality thanks to extra data bit rate performance.
It is upwardly compatible with conventional Dolby
Digital, so it offers greater fl exibility in response to
the source signal and the conditions of the playback
equipment.
Dolby TrueHD
Dolby TrueHD is a high defi nition audio technology
developed by Dolby Laboratories, using lossless
coding technology to faithfully reproduce the sound
of the studio master.
This format provides the facility to support up to
8 audio channels with a sampling frequency of
48
96kHz/24bit resolution and up to 6 audio channels
with a sampling frequency of 192kHz/24bit
resolution. Dolby TrueHD is adopted for applications
that put very high importance on sound quality.
Dolby Pro Logic g
Dolby Pro Logic g is a matrix decoding technology
developed by Dolby Laboratories.
Regular music such as that on CDs is encoded into
5 channels to achieve an excellent surround effect.
The surround channel signals are converted into
stereo and full band signals (with a frequency
response of 20 Hz to 20 kHz or greater) to create
a "three-dimensional" sound image offering a rich
sense of presence for all stereo sources.
Dolby Pro Logic gx
Dolby Pro Logic gx is a further improved version of
the Dolby Pro Logic g matrix decoding technology.
Audio signals recorded in 2 channels are decoded
to achieve a natural sound with up to 7.1 channels.
There are three modes: "Music" suited for playing
music, "Cinema" suited for playing movies, and
"Game" which is optimized for playing games.
Downmix
This function converts the number of channels of
surround audio to less number of channels and
plays back.
DTS
This is an abbreviation of Digital Theater System,
which is a digital audio system developed by DTS.
When playing back audio by connecting this system
with a device such as DTS amplifi er, accurate sound
fi eld position and realistic sound effect as if you are
in a movie theater can be obtained.
DTS 96/24
DTS 96/24 is a digital audio format enabling high
sound quality playback in 5.1 channels with a
sampling frequency of 96 kHz and 24 bit quantization
on DVD-Video.
DTS Digital Surround
DTS Digital Surround is the standard digital surround
format of DTS, Inc., compatible with a sampling
frequency of 44.1 or 48 kHz and up to 5.1 channels
of digital discrete surround sound.
DTS-ES™ Discrete 6.1
DTS-ES™ Discrete 6.1 is a 6.1-channel discrete
digital audio format adding a surround back (SB)
channel to the DTS digital surround sound.
Decoding of conventional 5.1-channel audio signals
is also possible according to the decoder.
DTS-ES™ Matrix 6.1
DTS-ES™ Matrix 6.1 is a 6.1-channel discrete digital
audio format inserting a surround back (SB) channel
to the DTS digital surround sound through matrix
encoding. Decoding of conventional 5.1-channel
audio signals is also possible according to the
decoder.
DTS Express
DTS Express is an audio format supporting low bit
rates (max. 5.1 channels, 24 to 256 kbps).
DTS-HD
This audio technology provides higher sound quality
and enhanced functionality than the conventional
DTS and is adopted as an optional audio for Blu-ray
Disc. This technology supports multi-channel, high
data transfer speed, high sampling frequency, and
lossless audio playback. Maximum 7.1-channels are
supported in Blu-ray Disc.
DTS-HD High Resolution Audio
DTS-HD High Resolution Audio is an improved
version of the conventional DTS, DTS-ES and
DTS 96/24 signals formats, compatible with
sampling frequencies of 96 or 48 kHz and up to
7.1 channels of discrete digital sound. High data
bit rate performance provides high quality sound.
This format is fully compatible with conventional
products, including conventional DTS
surround 5.1-channel data.
DTS-HD Master Audio
DTS-HD Master Audio is a lossless audio format
created by Digital Theater System (DTS). This
format provides the facility to support up to 8 audio
channels with a sampling frequency of 96kHz/24bit
resolution and up to 6 audio channels with a
sampling frequency of 192kHz/24bit resolution.
It is fully compatible with conventional products,
including conventional DTS digital surround
5.1-channel data.
DTS NEO:6™ Surround
DTS NEO:6™ is a matrix decoding technology
for achieving 6.1-channel surround playback
with 2-channel sources. It includes "DTS NEO:6
Cinema" suited for playing movies and "DTS
NEO:6 Music" suited for playing music.
Dynamic range
The difference between the maximum undistorted
sound level and the minimum discernible level
above the noise emitted by the device.
H
HDCP
When transmitting digital signals between devices,
this copyright protection technology encrypts
the signals to prevent content from being copied
without authorization.
HDMI
This is an abbreviation of High-Defi nition Multimedia
Interface, which is an AV digital interface that can
be connected to a TV or amplifi er. Video signal and
audio signal can be connected using 1 cable.
L
LFE
This is an abbreviation of Low Frequency Effect,
which is an output channel that emphasizes
low frequency effect sound. Surround audio is
intensifi ed by outputting 20 Hz to 120 Hz deep
bass.
M
MP3 (MPEG Audio Layer-3)
This is an internationally standardized audio data
compression scheme, using the "MPEG-1" video
compression standard. It compresses the data
volume to about one eleventh its original size while
maintaining sound quality equivalent to a music CD.
digital
MPEG (Moving Picture Experts Group), MPEG-2,
MPEG-4
These are the names for digital compression format
standards used for the encoding of video and audio.
Video standards include "MPEG-1 Video", "MPEG-
2 Video", "MPEG-4 Visual", "MPEG-4 AVC". Audio
standards include "MPEG-1 Audio", "MPEG-2
Audio", "MPEG-4 AAC".
P
Protection Circuit
This is a function to prevent damage to components
within the power supply when an abnormality
such as an overload, excess voltage occurs or
temperature for any reason.
In this unit, the power indicator blinks and the unit
enters standby mode when an abnormality occurs.
S
Sampling frequency
Sampling involves taking a reading of a sound wave
(analog signal) at regular intervals and expressing
the height of the wave at each reading in digitized
