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 discs.
Dolby Digital Plus
Dolby Digital Plus is a compressed digital audio format developed by Dolby Laboratories, Inc. that supports
7.1-channel audio. Dolby Digital Plus remains fully compatible with the existing multichannel audio systems
that support Dolby Digital. This technology is used for audio on BD (Blu-ray discs).
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
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.
