Digital audio compression technology that
Digital Theater Systems, Inc. developed.
This technology conforms to 5.1-channel
surround sound. The rear channel is stereo
and there is a discrete subwoofer channel in
this format. DTS provides the same 5.1
discrete channels of high quality digital
audio.
Good channel separation is realized because
all of the channel data is recorded discretely
and little deterioration is realized because all
channel data processing is digital.
DVD VIDEO (page 6)
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 is 4.7 GB (Giga Byte),
which is 7 times that of a CD. The data
capacity of a double-layer and single-sided
DVD is 8.5 GB, a single-layer and double-
sided DVD is 9.4 GB, and double-layer and
double-sided DVD is 17GB.
The picture data uses the MPEG 2 format,
one of the worldwide standards of digital
compression technology. The picture data is
compressed to about 1/40 (average) of its
original size. The DVD also uses a variable
rate coding technology that changes the data
to be allocated according to the status of the
picture. Audio information is recorded in a
multi-channel format, such as Dolby Digital,
allowing you to enjoy a more real audio
presence.
Furthermore, various advanced functions
such as the multi-angle, multilingual, and
Parental Control functions are provided with
the DVD.
DVD-RW (page 6)
A DVD-RW is a recordable and rewritable
disc with the same size as the DVD VIDEO.
The DVD-RW can be recorded in two
different modes: VR mode and Video mode.
VR (Video Recording) mode enables various
programming and editing functions, some of
which are limited in the case of Video mode.
Video mode complies with DVD VIDEO
format and is compatible with DVD players
while a DVD-RW recorded in VR mode can
only be played on DVD-RW compliant
players. The “DVD-RW” appears in this
manual, or the on-screen display refers to
DVD-RWs in VR mode.
Film based software (page 85)
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.
Interlace format (page 84)
Interlace format shows every other line of an
image as a single “field” and is the standard
method for displaying images on television.
The even number field shows the even
numbered lines of an image, and the odd
numbered field shows the odd numbered
lines of an image.
Index (SACD/CD)/Video Index (VIDEO CD)
A number that divides a track into sections to
easily locate the point you want on an SACD/
CD or VIDEO CD. Depending on the disc, no
index may be recorded.
Parental Control (page 72)
A function of the DVD used to limit playback
of the disc according to the age of the user
and the limitation level in each country. The
limitation varies from disc to disc; when it is
activated, or playback is completely
prohibited, violent scenes are skipped or
replaced with other scenes, etc.
