Cinema Studio EX
A surround sound mode that can be regarded
as the compilation of Digital Cinema Sound
technology, delivers the sound of a dubbing
theater using three technologies: “Virtual
Multi Dimensions,” “Screen Depth Matching,”
and “Cinema Studio Reverberation.”
“Virtual Multi Dimensions,” the virtual
speaker technology, creates a virtual multi-
surround environment with actual speakers up
to 7.1 channels, and brings the surround sound
experience of a theater with the latest facilities
into your home.
“Screen Depth Matching” reproduces treble
attenuation, fullness, and depth of sound
usually created in a theater using sound
emission from behind the screen. This is then
added to the front and center channels.
“Cinema Studio Reverberation” reproduces
the sound characteristics of state-of-the-art
dubbing theaters and recording studios,
including Sony Pictures Entertainment’s
dubbing studios. There are three modes, A/B/
C, available according to the studio type.

Component video
A format for transmitting video signal
information consisting of three separate
signals: luminance Y, chrominance Pb, and
chrominance Pr. High quality pictures, such as
DVD video or HDTV pictures, are transmitted
more faithfully. The three jacks are color-
coded green, blue, and red.
x
Composite video
A standard format for transmitting video
signal information. The luminance signal Y
and chrominance signal C are combined and
transmitted together.
x
Crossover frequency
The frequency at which two speaker’s
frequencies intersect.
x
DeepColor
Video signals for which the color depth of
signals passing through an HDMI jack have
been raised.
The number of colors that could be expressed
by 1 pixel was 24 bits (16,777,216 colors) with
the current HDMI jack. However, the number
of colors which can be expressed by 1 pixel
will be 36, etc., bits when the receiver
corresponds to DeepColor.
Since the gradation of the depth of a color can
be expressed more finely with more bits,
continuous color changes can be more
smoothly expressed.

Digital Cinema Sound (DCS)
Unique sound reproduction technology for
home theater developed by Sony, in
cooperation with Sony Pictures Entertainment,
for enjoying the exciting and powerful sound
of movie theaters at home. With this “Digital
Cinema Sound” developed by integrating a
DSP (Digital Signal Processor) and measured
data, the ideal sound field intended by
filmmakers can be experienced at home.

Digital Concert Hall
“Digital Concert Hall” delivers richer sound
for 2ch stereo sources such as CDs, etc. With
the use of 5.1ch or 7.1ch speakers and virtual
speaker technology, stereoscopic
reverberation and reflected sound are
reproduced, and music software can be
enjoyed with richer sound and presence. The
sound field in a concert hall is recreated by a
geometrical analysis of the concert hall and
precise modeling of reflected and reverberant
sounds based on actual measured data. Tonal
qualities such as sound strength and frequency
response are taken into account and calculated
on the DSP (Digital Signal Processor) to bring
reverberation in. Sound is enjoyed with natural
and comfortable resonance, as if listening to
music in a concert hall.
