Glossary

Album
Section of a music piece or an image on a DATA
CD/DVD containing MP3/WMA audio tracks or
JPEG files.
Chapter
Subdivision of a title on a DVD. A title is composed
of several chapters.
®
DivX
Digital video technology created by DivX, Inc.
Videos encoded with DivX technology are among
the highest quality with a relatively small file size.
Dolby Digital
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.
DVD
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 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
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
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.
File
An MP3/WMA track, JPEG image, or a DivX video
on a DATA CD/DATA DVD. ("File" is an exclusive
definition for this unit.) A single file consists of a
single track, image, or movie.
Film based software, Video based software
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.
Scene
On a VIDEO CD with PBC (playback control)
functions, the menu screens, moving pictures and
still pictures are divided into sections called
"scenes."
Title
The longest section of a picture or music feature on
a DVD, movie, etc., in video software, or the entire
album in audio software.
Track
Section of a picture or a music piece on a VIDEO
CD, CD, or MP3/WMA. An album is composed of
several tracks (MP3/WMA only).
VIDEO CD
A compact disc that contains moving pictures.
The picture data uses the MPEG 1 format, one of a
worldwide standard of digital compression
technology. The picture data is compressed to about
1/140 of its original size. Consequently, a 12 cm
VIDEO CD can contain up to 74 minutes of moving
pictures.
VIDEO CDs also contain compact audio data.
Sounds outside the range of human hearing are
compressed while sounds we can hear are not
compressed. VIDEO CDs can hold 6 times the
audio information of conventional audio CDs.
There are 3 versions of VIDEO CDs.
• Version 1.0, 1.1: You can play only moving
pictures and sound.
• Version 2.0: You can play high-resolution still
pictures and enjoy PBC functions.
This unit conforms to all 3 versions above.
