Dolby Digital EX
Dolby Digital EX is a 6.1-channel surround format
proposed by Dolby Laboratories that allows users
to enjoy in their homes the “DOLBY DIGITAL
SURROUND EX” audio format jointly developed by
Dolby Laboratories and Lucas Films.
The 6.1 channels of sound, including surround back
channels, provide improved sound positioning and
expression of space.
Dolby Digital Plus
Dolby Digital Plus is an improved Dolby Digital signal
format that is compatible with up to 7.1 channels
of discrete digital sound and also improves sound
quality thanks to extra data bit rate performance.
It is upwardly compatible with conventional Dolby
Digital, so it offers greater flexibility in response to
the source signal and the conditions of the playback
device.
Dolby Pro Logic g
Dolby Pro Logic g is a matrix decoding technology
developed by Dolby Laboratories.
Regular music such as that on CDs is encoded into
5 channels to achieve an excellent surround effect.
The surround channel signals are converted into
stereo and full band signals (with a frequency
response of 20 Hz to 20 kHz or greater) to create
a “three-dimensional” sound image offering a rich
sense of presence for all stereo sources.
Dolby Pro Logic gx
Dolby Pro Logic gx is a further improved version of
the Dolby Pro Logic g matrix decoding technology.
Audio signals recorded in 2 channels are decoded
to achieve a natural sound with up to 7.1 channels.
There are three modes: “Music” suited for playing
music, “Cinema” suited for playing movies, and
“Game” which is optimized for playing games.
Dolby Pro Logic gz
Dolby Pro Logic gz introduces a new dimension to
Home Entertainment through the addition of a pair
of front height channels. Compatible with stereo,
5.1-channel and 7.1-channel content, Dolby Pro
Logic gz provides enhanced spaciousness, depth
and dimension to movies, concert video and video
game playback while maintaining the full integrity
of the source mix.
Dolby Pro Logic gz identifies and decodes spatial
cues that occur naturally in all content, directing
this information to the front height channels,
complementing the performance of left and right
surround sound speakers. Content that is encoded
with Dolby Pro Logic gz height channel information
Explanation of terms
can be even more revealing, with perceptually
discrete height channel information bringing an
exciting new dimension to home entertainment.
Dolby Pro Logic gz, with front height channels is
also an ideal alternative for households that cannot
support the placement of back surround speakers
of a typical 7.1-channel system but may have
bookshelf space available to support the addition of
height speakers.
Dolby TrueHD

with a sampling frequency of 192kHz/24bit
resolution. Dolby TrueHD is adopted for applications
that put very high importance on sound quality.
Downmix
This function converts the number of channels of
surround audio to less number of channels and
plays back.
