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.

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.

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.

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.

With the composite video signal system, color, brightness, and synchronization data signals are combined 
and transmitted with a single cable.

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 (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 

“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.

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.

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.

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 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.
