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 23, 59)
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 is recorded
discretely and little deterioration is realized
because all channel data processing is digital.
Dolby Surround (Pro Logic) (page 22)
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 23, 60)
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 (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 it’s
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
Dolby Digital as well as in PCM, 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.
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 VIDEO
CD or CD. Depending on the disc, no index
may be recorded.
Parental Control (page 47)
A function of the DVD used to limit playback
of the disc according to the age of the user
and the limitation level in each country. The
limitation varies from disc to disc; when it is
activated, or playback is completely
prohibited, violent scenes are skipped or
replaced with other scenes, etc.
Region Code (page 6)
This system is used to protect copyrights. A
region number is allocated on each DVD
player or DVD disc according to the sales
region. Each region code is shown on the
player as well as on the disc packaging. The
