Sound field program information

CINEMA DSP
Since the Dolby Surround and DTS systems were originally designed for
use in movie theaters, their effect is best felt in a theater having many
speakers designed for acoustic effects. Since home conditions, such as
room size, wall material, number of speakers, and so on, can differ so
widely, it is inevitable that there are differences in the sound that is heard.
Based on a wealth of actually measured data, Yamaha CINEMA DSP uses
Yamaha's original DSP technology to combine Dolby Pro Logic, Dolby
Digital, and DTS systems to provide the audiovisual experience of a movie
theater in the listening room of your own home.
Compressed Music Enhancer
The Compressed Music Enhancer feature of this unit enhances your
listening experience by regenerating the missing harmonics in compression
artifacts. As a result, it compensates for flattened complexity due to the loss
of high-frequency fidelity as well as lack of bass due to the loss of low-
frequency bass, providing 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 field
program, 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 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

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 TV), 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

"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
were not hitherto possible. 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.
