x Music mode
The Music mode is for use with any stereo music
recordings, and provides a wide and deep sound
space.
DTS
Digital audio compression technology
developed by DTS, Inc. This technology
conforms to 5.1-channel surround. This format
comprises of stereo rear channel and there is
discrete subwoofer channel in this format. 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 in
digitally.
DVD
A disc that contains up to 8 hours of moving
pictures even though its diameter is the same as
a CD.
The data capacity of a single-layer and single-
sided DVD, at 4.7 GB (Giga Byte), is 7 times
that of a CD. Furthermore, the data capacity of a
dual-layer and single-sided DVD is 8.5 GB, a
single-layer and double-sided DVD 9.4 GB, and
a dual-layer and double-sided DVD 17 GB.
The picture data uses the MPEG 2 format, one of
a worldwide standard of digital compression
technology. The picture data is compressed to
about 1/40 of its original size. The DVD also
uses the variable rate coding technology that
processes allocated data according to the status
of the picture.
The audio data is recorded in Dolby Digital as
well as in PCM, allowing you to enjoy more
realistic audio presence.
Furthermore, various advanced functions such
as the multi-angle, multilingual, and Parental
Control functions are provided with the DVD.
DVD+RW
A DVD+RW (plus RW) is a recordable and
rewritable disc. DVD+RWs use a recording
format that is comparable to the DVD VIDEO
format.
DVD-RW
A DVD-RW is a recordable and rewritable disc
that is the same size as a DVD VIDEO. The
DVD-RW has two different modes: VR mode
and Video mode. DVD-RWs created in Video
104
GB
mode have the same format as a DVD VIDEO,
while discs created in VR (Video Recording)
mode allow the contents to be programmed or
edited.
File
A JPEG image or a DivX video recorded on a
DATA CD/DATA DVD. ("File" is an exclusive
definition for this system.) A single file consists
of a single image or movie.
Film based software, Video based
software
DVDs can be classified as film based or video
based software. Film based DVDs contain the
same images (24 frames per second) that are
shown at movie theaters. Video based DVDs,
such as television dramas or sit-coms, displays
images at 30 frames (or 60 fields) per second.
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
contents 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
lines and then odd numbered scanning lines, at
60 times per second.
Mica-reinforced-cellular-diaphragm
The Mica-reinforced-cellular-diaphragm is
made of a light weight and highly rigid
composite material that consists of Mica flake
and synthetic fiber.
It is constructed with layers of Mica flake. This
construction realizes diaphragm with low
density and high rigidity at the same time.
In this system, a Mica-reinforced-cellular-
diaphragm is used for the subwoofer.
