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 22, 58)
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 21)
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 22, 58)
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 the same 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 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.
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.
Interlace format (page 17)
Interlace format shows every other line of an
image as a single “field” and is the standard
method for displaying images on television.
The even number field shows the even
numbered lines of an image, and the odd
numbered field shows the odd numbered lines
of an image.
