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.

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, with a dynamic range of 120 dB. This unit can transmit

or receive DSD signals via the HDMI jack.

LFE 0.1 channel

This channel reproduces low-frequency bass signals, and has a frequency range 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-channels in Dolby Digital or DTS 5.1-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.

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 accuracy 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, whereas 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 accurately the sound level can be reproduced.

SILENT CINEMA

Yamaha has developed a natural, realistic sound effect DSP algorithm for headphones. Parameters

for headphones have been set for each sound program, so that accurate representations of all the

sound programs can be enjoyed on headphones.

Virtual CINEMA DSP

Yamaha has developed a Virtual CINEMA DSP algorithm that allows you to enjoy DSP surround

effects even without any surround speakers, by using virtual surround speakers. It is even possible

to enjoy Virtual CINEMA DSP using a minimal two-speaker system that does not include a center

speaker.

Video information

Component video signal

With the component video signal system, the video signal is separated into the Y signal for

luminance and the P

B and PR signals for chrominance. Color can be reproduced more faithfully with

this system because each of these signals is independent. The component signal is also called the

“color difference signal” because the luminance signal is subtracted from the color signal. A monitor

with component input jacks is required in order to output component signals.

Composite video signal

With the composite video signal system, the video signal comprises the three basic elements of a

video picture: color, brightness and synchronization data. A composite video jack on a video

component transmits these three elements combined.

Deep Color

Deep Color refers to the use of various color depths in displays, up from the 24-bit depths in

previous versions of the HDMI specification. This extra bit depth allows HDTVs and other displays

increase from millions of colors to billions of colors and eliminate on-screen color banding for smooth

tonal transitions and subtle gradations between colors. The increased contrast ratio can represent

many times more shades of gray between black and white. Additionally, Deep Color increases the

number of available colors within the boundaries defined by the RGB or YCbCr color space.

HDMI

HDMI (High-Definition Multimedia Interface) is the first industry supported, uncompressed, all-digital

audio/video interface. Providing an interface between any sources (such as set-top boxes or AV

receivers) and audio/video monitors (such as digital televisions), HDMI supports standard,

enhanced or high-definition video as well as multichannel 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/.”
