x Dolby Pro Logic II
This technology converts 2 channel stereo
recorded audio into 5.1 channel for playback.
There is a MOVIE mode for movies and
MUSIC mode for stereo sources such as
music. Old movies encoded in the traditional
stereo format can be enhanced with 5.1
channel surround sound.
x 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).
x 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.
x DTS 96/24
A high sound quality digital signal format. It
records audio at a sampling frequency and bit
rate of 96 kHz/24bit which is the highest
possible for DVD video. The number of
playback channels varies depending on the
software.
x 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.
x 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
surround left and surround right channels. It is
ideal for playback of motion picture
soundtracks.
x 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.
x HDMI (High-Definition
Multimedia Interface)
HDMI is an interface that supports both video
and audio on a single digital connection. The
HDMI connection carries standard to high
definition video signals and multi channel
audio signals to audio/video components, such
as HDMI equipped TVs, in digital form
without degradation. The HDMI specification
supports HDCP (High-bandwidth Digital
Contents Protection), a copy protection
technology that incorporates coding
technology for digital video signals.
x 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.
