Dolby Digital identifi es the use of Dolby Digital audio
coding for such consumer formats as DVD and
DTV. As with fi lm sound, Dolby Digital can provide
up to fi ve full-range channels for left, center, and
right screen channels, independent left and right
surround channels, and a sixth (".1") channel for
low-frequency effects.
Dolby Surround Pro Logic II is an improved matrix
decoding technology that provides better spatiality
and directionality on Dolby Surround program
material; provides a convincing three-dimensional
soundfi eld on conventional stereo music recordings;
and is ideally suited to bring the surround experience
to automotive sound. While conventional surround
programming is fully compatible with Dolby Surround
Pro Logic II decoders, soundtracks will be able to be
encoded specifi cally to take full advantage of Pro
Logic II playback, including separate left and right
surround channels. (Such material is also compatible
with conventional Pro Logic decoders.)
Dolby Digital EX creates six full-bandwidth output
channels from 5.1-channel sources. This is done
using a matrix decoder that derives three surround
channels from the two in the original recording. For
best results, Dolby Digital EX should be used with
movies soundtracks recorded with Dolby Digital
Surround EX.
About Dolby Pro Logic IIx
Dolby Pro Logic IIx technology delivers a natural
and immersing 7.1-channel listening experience
to the home theater environment. A product of
Dolby's expertise in surround sound and matrix
decoding technologies, Dolby Pro Logic IIx is a
complete surround sound solution that maximizes
the entertainment experience from stereo as well
as 5.1-channel encoded sources.
Dolby Pro Logic IIx is fully compatible with Dolby
Surround Pro Logic technology and can optimally
decode the thousands of commercially available
Dolby Surround encoded video cassettes and
television programs with enhanced depth and
spatiality. It can also process any high-quality
stereo or Advanced Resolution 5.1-channel music
content into a seamless 6.1- or 7.1-channel listening
experience.
Dolby Pro Logic IIz Height is designed to more
effectively use existing program material when
height channel speaker outputs are present. Dolby
Pro Logic IIz Height can be used to upmix a variety of
sources from movies and music, but are particularly
well-suited to upmix game content.
The Dolby Headphone technology provides a
surround sound listening experience over
headphones.
When listening to multichannel content such as DVD
movies over headphones, the listening experience is
fundamentally different than listening to speakers.
Since the headphone speaker drivers are covering
the pinna of the ear, the listening experience differs
greatly from traditional speaker playback. Dolby
utilizes patented headphone perspective curves to
solve this problem and provides a non-fatiguing,
immersive, home theater listening experience.
Dolby Headphone also delivers exceptional 3D
audio from stereo material.
