APPENDIX ➤ Glossary En 74

WMA (Windows Media Audio)

One of the compressed digital audio formats developed by Microsoft Corporation. With psychoacoustic

technologies, this compression method achieves a high compression rate. Reportedly, it is capable of

compressing data quantity by about 1/20 maintaining a certain level of audio quality.

■ Others

LFE (Low Frequency Effects) 0.1 channel

This channel reproduces low-frequency bass signals and has a frequency range from 20 Hz to 120 Hz. This

channel is added to the channels for all bands with Dolby Digital or DTS to enhance low frequency audio

effects. This channel is labeled 0.1 because it is limited to only low frequency audio.

Lip sync

Video output sometimes lags behind audio output due to the complexity of signal processing caused by an

increase in video signal capacity. Lip sync is a technique for automatically correcting the timing lag

between audio and video output.

HDMI and video information

Component video signal

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

the Pb and Pr signals for chrominance. Color can be reproduced more faithfully with this system because

each of these signals is independent.

Composite video signal

With the composite video signal system, color, brightness, and synchronization data signals are combined

and transmitted with a single cable.

Deep Color

Deep Color is a technology that HDMI specification supports. Deep Color increases the number of available

colors within the boundaries defined by the RGB or YCbCr color space. Conventional color systems

process the color using 8 bits. Deep Color processes the color with 10, 12, or 16 bits. This technology

allows HDTVs and other displays to increase from millions of colors to billions of colors and eliminate

on-screen color banding for smooth tonal transitions and subtle gradations between colors.

HDMI

HDMI (High-Definition Multimedia Interface) is the world-wide standard interface for digital audio/video

signal transmission. This interface transmits both digital audio and digital video signals using a single cable

without any loss. HDMI complies with HDCP (High-bandwidth Digital Content Protection) and provides a

secure audio/video interface. For further information on HDMI, visit the HDMI website at

“http://www.hdmi.org/”.

x.v.Color

“x.v.Color” is a technology that the HDMI specification supports. It is a more extensive color space than

sRGB and allows the expression of colors that were not hitherto possible. While remaining compatible with

the color gamut of sRGB standards, “x.v.Color” expands the color space, and thus can produce more vivid,

natural images.

Yamaha technologies

CINEMA DSP (Digital Sound Field Processor)

Since the Dolby Surround and DTS systems were originally designed for use in movie theaters, their effect is

best experienced in a theater that has many speakers designed for acoustic effects. Since home conditions

(such as room size, wall material, and number of speakers) can differ so widely, it is inevitable that there are

differences in the sound that you hear. Based on a wealth of actually measured data, CINEMA DSP,

Yamaha’s original DSP technology provides the audiovisual experience of a movie theater in your own

home.

Compressed Music Enhancer

The Compressed Music Enhancer feature compensates for missing harmonics in compression music

formats (such as MP3). As a result, this technology provides improved performance for the overall sound

system.

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

Virtual CINEMA DSP allows the system to virtually reproduce the sound field of the surround speakers with

front left and right speakers. Even if the surround speakers are not connected, the unit creates the realistic

sound field in a listening room.
