• DSD
Direct Stream Digital (DSD) technology stores audio signals on
digital storage media, such as Super Audio CDs. Using DSD, signals
are stored as single bit values at a high-frequency sampling rate
of
2.8224 MHz, while noise shaping and oversampling are used to
reduce distortion, a common occurrence with very high quantization
of
audio signals. Due to the high sampling rate, better audio quality
can be achieved than that offered by the PCM format used for normal
audio CDs. The frequency is equal to or higher than
100kHz
and the
dynamic range is 120 dB. This unit can transmit or receive DSD
signals input from the HDMI jack.
• DTS 96/24
DTS 96/24 offers an unprecedented level
of
audio quality for multi-
channel sound on DVD video, and is fully backward-compatible with
all DTS decoders. "96" refers to a 96 kHz sampling rate compared to
the typical 48 kHz sampling rate. "24" refers to 24-bit word length.
DTS 96/24 offers sound quality transparent to the original 96/24
master, and 96/24
5.
I-channel sound with full-quality full-motion
video for music programs and motion picture soundtracks on DVD
video.
• DTS Digital Surround
DTS digital surround was developed to replace the analog soundtracks
of
movies with a 5.l-channel digital sound track, and is now rapidly
gaining popularity in movie theaters around the world. DTS, Inc. has
developed a home theater system so that you can enjoy the depth
of
sound and natural spatial representation
of
DTS digital surround
in
your home. This system produces practically distortion-free 6-channel
sound (technically, front left and right, center, surround left and right,
and LFE
0.1
(subwoofer) channels for a total
of
5.1
channels). This
unit incorporates a DTS-ES decoder that enables
6.
I-channel
reproduction
by
adding the surround back channel to the existing 5.1-
channel formal.
• OTS Express
This
is
an audio format for next-generation optical discs such as Blu-
ray discs. It uses optimized low bit rate signals for network streaming.
In
the case
of
a Blu-ray disc, this format is used with secondary audio,
enabling you to enjoy the commentary
of
the movie producer via the
Internet while playing the main program.
• OTS-HO High Resolution Audio
DTS-HD High Resolution Audio
is
a high resolution audio
technology developed for high-definition disc-based media including
Blu-ray Disc. Selected as an optional audio standard for Blu-ray Disc,
this technology delivers sound that is virtually indistinguishable from
the original, offering a high-definition home theater experience.
Supporting bitrates
up
to 6.0 Mbps for Blu-ray Disc, DTS-HD High
Resolution Audio can carry
up
to
7.1
discrete channels
of
24-bit/96
kHz audio simultaneously.
DTS-HD High Resolution Audio also remains fully compatible with
the existing multichannel audio systems that incorporate DTS Digital
Surround.
• DTS-HO Master Audio
DTS-HD Master Audio is an advanced lossless audio technology
developed for high-definition disc-based media including Blu-ray
Disc. Selected as an optional audio standard for Blu-ray Disc, this
technology delivers sound that
is
bit-for-bit identical to the studio
master, offering a high-definition home theater experience.
Supporting bitrates
up
to
24.5 Mbps for Blu-ray Disc, DTS-HD
Master Audio can carry up to
7.1
discrete channels
of
24-bit/96 kHz
audio simultaneously. Supported by HDMI version 1.3 and designed
for the optical disc players and
AV
receivers/amplifiers
of
the future,
DTS-HD Master Audio also remains fully compatible with the
existing multichannel audio systems that incorporate DTS Digital
Surround.

• FLAC
This is a file format for lossless audio data compression. FLAC is
inferior to lossy compression formats in compression rate but provides
higher audio quality.
• HOMI
HDMI (High-Definition Multimedia Interface)
is
the first industry-
supported, uncompressed, all-digital audio/video interface. Providing
an interface between any source (such
as
a set-top box or
AV
receiver)
and an audio/video monitor (such
as
a digital television), HDMI
supports standard, enhanced or high-definition video as well as multi-
channel digital audio using a single cable. HDM! transmits all ATSC
HDTV standards and supports 8-channel digital audio, with
bandwidth to spare to accommodate future enhancements and
requirements.
When used in combination with HDCP (High-bandwidth Digital
Content Protection), HOMI provides a secure audio/video interface
that meets the security requirements
of
content providers and system
operators. For further information on HDMI, visit the HDM! website
at ''http://www.hdmi.orgf'.
• LFE
0.1
channel
This channel reproduces low-frequency signals. The frequency range
of
this channel is from 20 Hz to 120 Hz. This channel is counted as
0.1
because it only enforces a low-frequency range compared to the
full-range reproduced
by
the other 5/6 channels
in
Dolby Digital
or
DTS
5.116.
I-channel systems.
• Neural Surround
Neural Surround represents the latest advancement in surround
technology and has been adopted by XM Satellite Radio for digital
radio broadcast
of
surround recordings and live events
in
surround
sound. Neural Surround employs psychoacoustic frequency domain
processing which allows delivery
of
a more detailed sound stage with
superior channel separation and localization
of
audio elements.
System playback
is
scalable from
5.1
to
7.1
multi-channel surround
playback.
• Neo:6
Neo:6 decodes the conventional 2-channel sources for 6- channel
playback by the specific decoder. It enables playback with the full-
range channels with higher separation just like digital discrete signal
playback. There are two modes available: "Music mode" for music
sources and "Cinema mode" for movie sources.
• PCM (Linear PCM)
Linear PCM is a signal format under which an analog audio signal is
digitized, recorded and transmitted without using any compression.
This is used as a method
of
recording CDs and DVD audio. The PCM
system uses a technique for sampling the size
of
the analog signal per
very small unit
of
time. Standing for "Pulse Code Modulation", the
analog signal is encoded as pulses and then modulated for recording.
• Sampling frequency and number
of
quantized bits
When digitizing an analog audio signal, the number
of
times the
signal is sampled per second is called the sampling frequency, while
the degree
of
fineness when converting the sound level into a numeric
value is called the number
of
quantized bits. The range
of
rates that
can be played back is determined based on the sampling rate, while
the dynamic range representing the sound level difference is
determined by the number
of
quantized bits. In principle, the higher
the sampling frequency, the wider the range
of
frequencies that can be
played back, and the higher the number
of
quantized bits, the more
finely the sound level can be reproduced.
