x Dolby Digital Plus
Dolby Digital Plus provides the flexibility and
efficiency to deliver more channels of
compelling surround sound for high-definition
video media. Its superior coding efficiencies
enable up to 7.1 channel of high-quality multi
channel audio without negatively impacting
bit budgets allocated for video performance or
additional feature sets.
x Dolby Digital Surround EX
Acoustic technology developed by Dolby
Laboratories, Inc. Surround back information
is matrixed into regular left and right surround
channels so that the sound can be reproduced
in 6.1 channel. Active scenes, especially, are
recreated with a more dynamic and realistic
sound field.
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 channels surround
sound. This is the most common audio
processing method for DVD video.
x Dolby TrueHD
Dolby TrueHD is Dolby's lossless audio
technology developed for high-definition
optical discs. Dolby TrueHD audio is bit-for-
bit identical to the original studio masters and
provides supreme-quality audio up to 8
channels at 96 kHz/24 bit and up to 6 channels
at 192 kHz/24 bit. Together with high-
definition video, it offers an unprecedented
home theater experience.
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.
