• HDMI

HDMI (Higll-Definifion Mukimedia Interface) is the first

induslry-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-definilion video as well as

mulfi-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 inlertace that meets the security requirements

of content providers and system operators. For filrther

intk)rmafion on HDML visit the HDMI website at

• LFEO.1 channel

This channel reproduces low-trequenc3, signals. The

frequency range of this channel is from 20 Hz to 120 Hz.

Tfiis channel is counted as 0.1 because it only enR)rces a

low-frequency range compared to the fidl-range

reproduced by the other 5 channels in Dolby Digital or

DTS 5.1 -channel systems.

• Neural Surround

Nenral Surround _vlvpresents the latest advancement in

surround technology and has been adopted by XM

Satellite Radio fi_rdigital radio broadcast of surround

recordings and live events ill surround sound. Neural

Surround _'_employs psychoacoustic frequency domain

processing which allows delivery of a morn detailed sound

stage with superior channel separation and localization of

audio elements.

• PCM (Linear PCM)

Linear PCM is a signa] tbrmat 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 t_r sampling tfie size of the analog signal per

very small unit of time. Standing tk)r"Pulse Code

Modulation", the ana]og signal is encoded as pulses and

then modulated fi)r recording.

• Sampling frequency and number of

quantized bits

When digitizing an analog audio signal, the nunlber of

times tfie signal is sampled per second is called the

sampling fi'equency, while the degree of fineness when

converting the sound ]evel into a numeric value is cal]ed

tfie nmnber of quanfized bits. The range of rates that can

be played back is determined based on the sampling rate,

while the d} namic range representing the sound level

difference is determined by the number of quantized bits.

Ill principle, the higher the sampling fi;equency, the wider

lhe range of frequencies lfiat can be played back, and the

higher the number of quantized bits, the more finely the

sound level can be reproduced.

• SILENT CINEMA

Yamahahas developed a natural, realistic sound effect

DSP algoritfimtk)rheadphones. Parameters fi)r

headphones have been set tBl"each sound field so that

accurate representations of all the sound field programs

can be enjoyed on headphones.

• Virtual CINEMA DSP

Yamaha has developed a Virtual CINEMA DSP algorithm

that allows you to enjoy DSP sound field sun'ound eft_cts

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.
