DCS (Digital Cinema Sound)
In collaboration with Sony Pictures
Entertainment, Sony measured the sound
environment of their studios and integrated the
data of the measurement with Sony DSP (Digital
Signal Processor) technology to develop
“Digital Cinema Sound.” “Digital Cinema
Sound” simulates in a home theater an ideal
movie theater sound environment based on the
preference of the movie director.
Digital Cinema Auto Calibration
Digital Cinema Auto Calibration was developed
by Sony to automatically measure and adjust the
speaker settings to your listening environment in
a short period of time.
Dolby Digital
This movie theater sound format is more
advanced than Dolby Surround Pro Logic. In
this format, the surround speakers output stereo
sound with an expanded frequency range, and a
subwoofer channel for deep bass is
independently provided. This format is also
called “5.1” with the subwoofer channel
designed as the 0.1 channel (since it functions
only when a deep bass effect is needed). All six
channels in this format are recorded separately
for superior channel separation. Furthermore,
since all the signals are processed digitally, less
signal degradation occurs.
Dolby Pro Logic II
Dolby Pro Logic II creates five full-bandwidth
output channels from 2 channel sources. This is
done using an advanced, high-purity matrix
surround decoder that extracts the spatial
properties of the original recording without
adding any new sounds or tonal colorations.

Movie mode
The Movie mode is for use with stereo television
shows and all programs encoded in Dolby
Surround. The result is enhanced sound field
directionality that approaches the quality of
discrete 5.1-channel sound.
x
Music mode
The Music mode is for use with any stereo music
recordings, and provides a wide and deep sound
space.
Dolby Surround Pro Logic
As one method of decoding Dolby Surround,
Dolby Surround Pro Logic produces four
channels from 2 channel sound. Compared with
the former Dolby Surround system, Dolby
Surround Pro Logic reproduces left-to-right
panning more naturally and localizes sounds
more precisely. To take full advantage of Dolby
Surround Pro Logic, you should have one pair of
surround speakers and a center speaker. The
surround speakers output monaural sound.
DTS
Digital audio compression technology
developed by DTS, Inc. This technology
conforms to 5.1-channel surround. This format
is comprised of a stereo rear channel and a
discrete subwoofer channel. DTS provides the
same 5.1 discrete channels of high quality digital
audio. The good channel separation is realized
due to the all channel data being recorded
discretely and processed digitally.
Dual Stereo Subwoofer
Whereas a conventional subwoofer provides
only a monaural signal in which the lower
frequencies of the left and right signals are
mixed together, a stereo subwoofer provides
independent lower frequencies from each
channel for a richer, lower ambience.
HDMI (High-Definition Multimedia
Interface)
HDMI is an interface that supports both video
and audio on a single digital connection,
allowing you to enjoy high quality digital
picture and sound. The HDMI specification
supports HDCP (High-bandwidth Digital
Content Protection), a copy protection
technology that incorporates coding technology
for digital video signals.
Interlace format
(Interlaced scanning)
The interlace format is the NTSC standard
method for displaying TV images at 30 frames
per second. Each frame is scanned twice -
alternately between the even numbered scanning
