Glossary
Chapter (page 9, 13, 53)
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.
Dolby Digital (page 24, 82)
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 are
recorded discretely and little deterioration is
realized because all channel data processing
is digital.
Dolby Surround (Pro Logic) (page 23, 81)
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 24, 82)
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 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 17 GB.
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, 36)
A DVD-RW is a recordable and rewritable
disc that is the same size as the 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 (page 6)
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
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.
