■ THX Select
Before any home theatre component can be THX Select
certified, it must incorporate pass a rigorous series of
quality and performance tests. Only then can a product
feature the THX Select logo, which is your guarantee that
the Home Theatre products you purchase will give you
superb performance for many years to come. THX Select
requirements cover every aspect of the product including
power amplifier and pre-amplifier performance and
operation, and hundreds of other parameters in both the
digital and analog domain.
■ THX Surround EX
THX Surround EX - Dolby Digital Surround EX is a joint
development of Dolby Laboratories and the THX Ltd.
In a movie theater, film soundtracks that have been
encoded with Dolby Digital Surround EX technology are
able to reproduce an extra channel which has been added
during the mixing of the program. This channel, called
Surround Back, places sounds behind the listener in
addition to the currently available front left, front center,
front right, surround right, surround left and subwoofer
channels. This additional channel provides the opportunity
for more detailed imaging behind the listener and brings
more depth, spacious ambience and sound localization
than ever before.
Movies that were created using the Dolby Digital
Surround EX technology, when released into the home
consumer market may exhibit wording to that effect on the
packaging. A list of movies created using this technology
can be found on the Dolby web site at www.dolby.com. A
list of available DVD software titles encoded with this
technology can be found at www.thx.com.
Only receiver and controller products bearing the THX
Surround EX logo, when in the THX Surround EX mode,
faithfully reproduce this new technology in the home.
This product may also engage the THX Surround EX
mode during the playback of 5.1 channel material that is
not Dolby Digital Surround EX encoded. In such cases the
information delivered to the Surround Back channel will
be program dependent and may or may not be pleasing
depending on the particular soundtrack and the tastes of
the individual listener.
■ Component video signal
With the component video signal system, the video signal
is separated into the Y signal for the luminance and the PB
and P
R signals for the chrominance. Color can be
reproduced more faithfully with this system because each
of these signals is independent. The component signal is
also called the “color difference signal” because the
luminance signal is subtracted from the color signal.
A monitor with component input jacks is required in order
to use the component signal for output.
■ Composite video signal
With the composite video signal system, the video signal
is composed of three basic elements of a video picture;
color, brightness and synchronization data. A composite
video jack on a video component transmits these three
elements combined.
■ S-video signal
With the S-video signal system, the video signal normally
transmitted using a pin cable is separated and transmitted
as the Y signal for the luminance and the C signal for the
chrominance through the S-video cable. Using the S
VIDEO jack eliminates video signal transmission loss and
allows recording and playback of even more beautiful
images.
