Audio information

Audio decoding format
Dolby Digital
Dolby Digital is a compressed digital audio format developed by Dolby Laboratories, Inc. that
supports 5.1-channel audio. This technology is used for audio on most DVD disc.
Dolby Pro Logic II
Dolby Pro Logic II enables 5-channel playback from 2-channel sources. There are three modes
available: “Music mode” for music sources, “Movie mode” for movie sources, and “Game mode”
for game sources.
DTS Digital Surround
DTS Digital Surround is a compressed digital audio format developed by DTS, Inc. that supports
5.1-channel audio. This technology is used for audio on most DVD discs.
DSD (Direct Stream Digital)
DSD (Direct Stream Digital) technology stores audio signals on digital storage media, such as
SACD (Super Audio CDs). The signals are stored at a high-frequency sampling rate of 2.8224
MHz. The highest frequency response is equal to or higher than 100 kHz, with a dynamic range of
120 dB. This technology offers better audio quality than that used for CDs.

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
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.
