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 24, 69)
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 cinema audio 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)
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, 69)
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 can be played on other DVD
players while a DVD-RW recorded in VR
mode can only be played on DVD-RW
compliant players. The "DVD-RW"
appearing in this manual, and the on-screen
displays refer to DVD-RWs in VR mode.
Film based software, Video based
software (page 66)
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.
Index (CD)/Video Index (VIDEO CD) (page
9)
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.
