Chapter (page 28)
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 (pages 22 and 45)
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 (page 23)
Audio signal processing technology that
Dolby Laboratories developed for surround
sound. When the input signal contains a
surround component, the process outputs the
front, center and rear signals. The rear
channel is monaural.
Digital audio compression technology that
DTS, 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 (page 7)
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.
A DVD+R (read “plus 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.
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.
The DVD-R 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.
