Glossary
Chapter (page 55)
Sections of a picture or a music feature
that are smaller than titles. A title is
composed of several chapters.
Depending on the disc, no chapters may
be recorded.
CPRM (page 35)
CPRM (Content Protection for
Recordable Media) is a coding
technology that protects copyrights for
images.
Dolby Digital (page 96)
Digital audio compression technology
developed by Dolby Laboratories. This
technology conforms to multi-channel
surround sound. The rear channel is
stereo and there is a discrete subwoofer
channel in this format. Dolby Digital
provides the same discrete channels of
high quality digital audio found in
“Dolby Digital” theater surround sound
systems. Good channel separation is
realized because all of the channel data is
recorded discretely and little
deterioration occurs because all channel
data processing is digital.
Dolby Surround (Pro Logic)
(page 96)
Audio signal processing technology that
Dolby Laboratories developed for
surround sound. When the input signal
contains a surround component, the Pro
Logic process outputs the front, center
and rear signals. The rear channel is
monaural.
DTS (page 96)
Digital audio compression technology
that Digital Theater Systems, Inc.
developed. This technology conforms to
multi-channel surround sound. The rear
channel is stereo and there is a discrete
subwoofer channel in this format. DTS
provides the same discrete channels of
high quality digital audio.
Good channel separation is realized
because all of the channel data is
recorded discretely and little
deterioration occurs because all channel
data processing is digital.
DVD VIDEO (page 49)
A disc that contains up to eight 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-R (page 35)
A DVD-R is a recordable disc that is the
same size as a DVD VIDEO. Contents
can be recorded only once to a DVD-R,
and will have the same format as a DVD
VIDEO.
DVD-RW (page 35)
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. DVDs 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 (page 35)
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.
Film based software, Video based
software (page 51)
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, display images at 30
frames (or 60 fields) per second.
Index (page 57)
A number that divides a track into
sections to easily locate the point you
want on a CD. Depending on the disc, no
index may be recorded.
Interlace format (page 51)
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.
Progressive format (page 51)
Compared to the Interlace format that
alternately shows every other line of an
image (field) to create one frame, the
Progressive format shows the entire
image at once as a single frame. This
means that while the Interlace format can
show 30 frames/60 fields in one second,
the Progressive format can show 60
frames in one second. The overall
picture quality increases and still images,
text, and horizontal lines appear sharper.
Title (page 55)
The longest section of a picture or music
feature on a DVD, movie, etc., in video
software, or the entire album in audio
software.
Track (page 55)
Sections of a music feature on a CD (the
length of a song).
