x 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.
x Digital Cinema Sound (DCS)
A 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.
x Dolby Digital
Digital audio encoding/decoding technology
developed by Dolby Laboratories, Inc. It
consists of front (left/right), center, surround
(left/right) and subwoofer channels. It is a
designated audio standard for DVD video and
also known as 5.1 channel surround. Since
surround information is recorded and
reproduced in stereo, more realistic sound with
fuller presence is delivered than with Dolby
surround.
x DTS Digital Surround
Digital audio encoding/decoding technology
for theaters developed by DTS, Inc. It
compresses audio less than Dolby Digital,
delivering a higher quality sound
reproduction.
x PCM (Pulse Code Modulation)
A method of converting analog audio to digital
audio for easy enjoyment of digital sound.
x Sampling frequency
To convert analog audio to digital, analog data
should be quantified. This process is called
sampling, and the number of times per second
the analog data is quantified is called the
sampling frequency. A standard music CD
stores data quantified at 44,100 times per
second, which is expressed as a sampling
frequency of 44.1 kHz. Generally speaking, a
higher sampling frequency means better sound
quality.
