Additional Information
Glossary
Chapter (page 9)
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 19, 67)
Digital audio compression technology
developed by Dolby Laboratories. This
technology conforms to 5.1-channel surround
sound. The rear channel is stereo and there is
a discrete subwoofer channel in this format.
Dolby Digital provides the same 5.1 discrete
channels of high quality digital audio found in
“Dolby Digital” theatre 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 19)
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, centre and rear signals. The
rear channel is monaural.
DTS (page 19, 67)
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 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 (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 (page 18)
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/60
fields (25 frames/50 fields) per second.
Index (CD)/Video Index (VIDEO CD) (page
12)
A number that divides a track into sections to
easily locate the point you want on a CD or
VIDEO CD. Depending on the disc, no index
may be recorded.
