• Dolby Pro Logic IIx
Technology for
7.1
channel (or
6.1
channel)
playback. Along with audio encoded in Dolby
Digital Surround EX,
5.1
channel Dolby
Digital encoded audio can be reproduced
in
7.1
channel (or
6.1
channel). Furthermore,
existing stereo recorded content can also be
reproduced in
7.1
channel (or
6.1
channel).
• Dolby Surround (Dolby Pro
Logic)
Audio processing technology developed by
Dolby Laboratories, Inc. Center and mono
surround information is matrixed into two
stereo channels. When reproduced, audio is
decoded and output in 4 channel surround
sound. This is the most common audio
processing method for DVD-video.
• DTS 96/24
A high sound quality digital signal format.
It
records audio at a sampling frequency and bit
rate
of
96kHz/24bit which
is
the highest
possible for DVD-video. The number
of
playback channels varies depending on the
software.
• DTS Digital Surround
Digital audio encoding/decoding technology
for theaters developed by DTS, Inc.
It
compresses audio less than Dolby Digital,
delivering a higher quality sound
reproduction.
• DTS-ES
Format for
6.1
channel playback with
surround back information. There are two
modes, "Discrete 6.1" which records all
channels independently, and "Matrix 6.1"
which matrixes surround back channel into LS
(left surround) and RS (right surround)
channels.
It
is ideal for playback
of
motion
picture soundtracks.
• DTS Neo:6
This technology converts 2 channel stereo
recorded audio for
6.1
channel playback.
There are two modes to select according to the
playback source or your preference, CINEMA
for movies, and MUSIC for stereo sources
such as music.
• HDMI (High-Definition
Multimedia Interface)
HDMI (High-Definition Multimedia
Interface) is an interface that supports both
video and audio on a single digital connection,
allowing you to enjoy high quality digital
picture and sound. The HDMI specification
supports HDCP (High-bandwidth Digital
Contents Protection), a copy protection
technology that incorporates coding
technology for digital video signals.
• PCM (Pulse Code Modulation)
A method
of
converting analog audio to digital
audio for easy enjoyment
of
digital sound.
• Sampling frequency
To convert analog audio to digital, analog data
should be quantified. This process is called
sampling, and the number
of
times per second
the analog data
is
quantified
is
called the
sampling frequency. A standard music CD
stores data quantified at 44,100 times per
second, which is expressed as a sampling
frequency
of
44.1 kHz. Generally speaking, a
higher sampling frequency means better sound
quality.
• x.v.Color
x.v.Color
is
a more familiar term for the
xvYCC standard proposed by Sony, and is a
trademark
of
Sony. xvYCC is an international
standard for color space
in
video.
This standard can express a wider color range
than the currently used broadcast standard.
