Glossary

■ 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 100 kHz and the

dynamic range is 120 dB. This unit can transmit or receive DSD

signals via 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 5.1-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 5.1-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 6.1-channel

reproduction by adding the surround back channel to the existing 5.1-

channel format.

■ DTS 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.

■ DTS-HD 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-HD 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.

■ HDMI

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. HDMI 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), HDMI provides a secure audio/video interface

that meets the security requirements of content providers and system

operators. For further information on HDMI, visit the HDMI website

at “http://www.hdmi.org/.”

■ 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 5.1/6.1-channel systems.

■ 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.

■ S-video signal

With the S-video signal system, the video signal normally transmitted

using a pin cable is separated and transmitted as the Y signal for the

luminance and the C signal for the chrominance through the S-video

cable. Using the S VIDEO jack eliminates video signal transmission

loss and allows recording and playback of even more beautiful

images.

■ 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.

■ “x.v.Color”

A color space standard supported by HDMI version 1.3. It is a more

extensive color space than sRGB, and allows the expression of colors

that could not be expressed before. While remaining compatible with

the color gamut of sRGB standards, “x.v.Color” expands the color

space and can thus produce more vivid, natural images. It is

particularly effective for still pictures and computer graphics.
