DTS
Digital audio compression technology
that the Digital Theater Systems, Inc.
developed. This technology conforms
to 5.1-channel surround. The surround
channel is stereo 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 because the
all channel data is recorded discrete and
processed in digital.
DVD VIDEO
A disc that contains up to 8 hours of
moving pictures even though its diameter
is the same as an AUDIO CD.
The data capacity of a single-layer and
single-sided DVD VIDEO, at 4.7 GB
(Giga Byte), is 7 times that of an AUDIO
CD. Furthermore, the data capacity of a
dual-layer and single-sided DVD VIDEO
is 8.5 GB, a single-layer and double-sided
DVD VIDEO 9.4 GB, and a dual-layer
and double-sided DVD VIDEO 17 GB.
The picture data uses the MPEG 2
format, one of the worldwide standards
for digital compression technology. The
picture data is compressed to about 1/40
of its original size. The DVD VIDEO
also uses variable rate coding technology
that changes the data to be allocated
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 VIDEO.
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
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.
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.
File
A JPEG image file recorded on a DATA
CD or 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
DVD VIDEOs can be classified as Film
based or Video based software. Film
based DVD VIDEOs contain the same
images (24 frames per second) that are
shown at movie theaters. Video based
DVD VIDEOs, such as television dramas
or sitcoms, displays images at 30 frames
(or 60 fields) per second.
