Dolby Digital identifies the use of Dolby Digital
audio coding for such consumer formats as DVD
and DTV. As with film sound, Dolby Digital can
provide up to five 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
s o u n d f i e l d o n c o n v e n t i o n a l s t e r e o m u s i c
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
specifically 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.
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.

Circle Surround II (CS-II) is a powerful and
versatile multichannel technology. CS-II is
designed to enable up to 6.1 multichannel
surround sound playback from mono, stereo, CS
encoded sources and other matrix encoded
sources. In all cases the decoder extends it into 6
channels of surround audio and a LFE/subwoofer
signal. The CS-II decoder creates a listening
environment that places the listener "inside" music
performances and dramatically improves both hi-fi
audio conventional surround-encoded video
material. CS-II provides composite stereo rear
channels to greatly improve separation and image
positioning – adding a heightened sense of realism
to both audio and A/V productions.
CS-II is packed with other useful feature like dialog
clarity (SRS Dialog) for movies and cinema-like
bass enrichment (TruBass). CS-II can enable the
dialog to become clearer and more discernable in
movies and it enables the bass frequencies
contained in the original programming to more
closely achieve low frequencies – overcoming the
low frequency limitations of the speakers by full
octave.
