GLOSSARY
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 P
B
 
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.
