•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 t_rmat used for normal audio CDs. The frequency is equal to or higher than 100 kHz 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 nmlti-
channel sound on DVD video, and is filly 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 96124 offers sound quality transparent to the original 96124
master, and 96124 5. l-channel sound with fill-quality fill-motion video tbr music programs and motion picture soundtracks on DVD video.
•DTS Digital Surround
DTS digital surround "a,as developed to replace the analog soundtracks of movies with a 5.1-channeldigital 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 6.1 -channel
reproduction by adding the surround back channel to the existing 5.1- channel format.
•DTS Express
This is an audio tbnnat tbr 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 lnternet while playing the main program.
•DTS-HD High Resolution Audio
DTS-HD High Resolution Audio is a high resolution audio
technology developed tUr 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-defnition home theater experience.
Supporting bitrates up to 6.0 Mbps tUr Blu-ray Disc, DTS-HD High
Resolution Audio can carry up to 7.1 discrete channels of 24-bit/96 kHz audio sinmltaneously.
DTS-HD High Resolution Audio also remains fldly compatible with
the existing multichannel audio systems that incorporate DTS Digital Surround.
•DTS-HD Master Audio
DTS-HD Master Audio is an advanced lossless audio technology
developed for high-defnifon disc-based media including Blu-ray Disc. Selected as an optional audio standard tUr 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 sinmltaneously. Supported by HDMI version 1.3 and designed
for the optical disc players and AV receivers/amplifiers of the fllture,
DTS-HD Master Audio also remains filly compatible with the
existing nmltichannel audio systems that incorporate DTS Digital Surround.
•FLAC
This is a fie t_rmat for lossless audio data compression. FLAC is
interior to lossy compression tbrmats in compression rate but provides higher audio quality.
•HDMI
HDMI (High-Defnition Multimedia Interface) is the frst 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. HDMI transmits all ATSC HDTV standards and supports 8-channel digital audio, with
bandwidth to spare to accommodate filture enhancements and requirements.
When used in combination with HDCP (High-bandwidth Digital Content Protection), HDMI provides a secure audio/video interface
that meets the security requirements of content providers and system
operators. For fimher information on HDMI, visit the HDMI website at "http://www.hdmi.org/".
•LFE0.1 channel
This channel reproduces lo'a,-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 ent_rces a low-frequency range compared to the tull-rangereproduced by the other 5/6 channels in Dolby Digital or DTS 5.1/6.1 -channel systems.
•Neural Surround
Neural Surround represents the latest advancement in surround technology and has been adopted by XM Satellite Radio t_r 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 t_r 6- channel playback by the specifc decoder. It enables playback with the fldl- range channels with higher separation just like digital discrete signal
playback. There are two modes available: "Music mode" for music sources and "Cinema mode" t_r movie sources.
•PCM (Linear PCM)
Linear PCM is a signal format under "a,hich 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 tUr sampling the size of the analog signal per
very small unit of time. Standing t_r "Pulse Code Modulation", the analog signal is encoded as pulses and then modulated for recording.
•Sampling frequency and number of
quantized bits
When digitizing :m 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 t?equencies that can be played back, and the higher the number of quantized bits, the more finely the sound level can be reproduced.
