■ Sound field program information
CINEMA DSP
Since the Dolby Surround and DTS systems were
originally designed for use in movie theaters, their effect
is best felt in a theater having many speakers designed for
acoustic effects. Since home conditions, such as room
size, wall material, number of speakers, and so on, can
differ so widely, it is inevitable that there are differences in
the sound heard. Based on a wealth of actually measured
data, Yamaha CINEMA DSP uses Yamaha original DSP
technology to combine Dolby Pro Logic, Dolby Digital
and DTS systems to provide the audiovisual experience of
movie theater in the listening room of your own home.
SILENT CINEMA
Yamaha has developed a natural, realistic sound effect
DSP algorithm for headphones. Parameters for
headphones have been set for each sound field program so
that accurate representations of all the sound field
programs can be enjoyed on headphones.
Virtual CINEMA DSP
Yamaha has developed a Virtual CINEMA DSP algorithm
that allows you to enjoy DSP surround effects even
without any surround speakers by using virtual surround
speakers. It is even possible to enjoy Virtual CINEMA
DSP using a minimal two-speaker system that does not
include a center speaker.
Video information
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
output component signals.
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.
