Dolby Digital
This digital audio format provides discrete 5.1-channel surround sound.
Dolby Digital source materials available include DVDs, LaserDiscs, HDTV
broadcasts, some satellite delivered programming, and the output of some
digital cable set top boxes.
Dolby Digital Surround EX
This processing mode is a joint development of Dolby Laboratories and the
THX division of LucasFilm, Ltd. Film soundtracks encoded with Dolby Digital
Surround EX technology contain an extra channel, added to the soundtrack
during mixing, called Surround Back, which places audio behind the listener
in addition to the existing front left, front center, front right, surround left,
surround right, and subwoofer channels. This additional channel provides
more detailed imaging behind the listener creating more depth, spacious
ambience and sound localization than before.
A list of movies created using Dolby Digital Surround EX can be found on
the Dolby web site at www.dolby.com.
NOTE: Both Surround EX and DTS-ES mode can also be engaged
during the playback of 5.1 channel material that is not Dolby Digital
Surround EX or DTS-ES encoded. When used this way, signals from
the left and right surrounds are used to synthesize the surround back
channel. Results using this method will vary, depending on the source
material and may enhance or detract from the viewing experience.
Dolby Pro Logic II
Dolby Pro Logic II is a substantial enhancement to the original Pro Logic
process. In addition to full-bandwidth surrounds, Pro Logic II provides three
unique user adjustable music processing options: Panorama, Dimension, and
Center Width. These choices are also available when employing the Cirrus
Extra Surround processing option with Pro Logic II Music mode.
Panorama provides an extension of the front stereo image around the listen-
ers into the surround channels, creating an enveloping wraparound effect.
Dimension enables adjustment of the surround image between the front
and rear of your room. Certain types of music can benet from the smoother
overall balance and more natural sounding image made possible by using
the Dimension control.
Center Width provides variable adjustment of the center channel image and
location, to create a more seamless front soundstage as well as control of the
sense of ‘width’ across the L/C/R loudspeaker array. A phantom center image
can also be created from just the left and right front speakers.
DTS
This digital data format is similar to Dolby Digital, but uses a higher sampling
rate. DTS also provides a maximum of 5.1 channel surround channels and
is available on compact disc, DVD and LaserDiscs. Audio-only DTS discs
may be used with any CD, LD or DVD player with a digital audio output, but
DVD discs with DTS audio must be used on players with the “DTS Digital
Out” logo.
