DVD+RW (page 8)
A DVD+RW (read “plus RW”) is a recordable and
rewritable disc. DVD+RWs use a recording
format that is comparable to the DVD VIDEO
format.
DVD-R (page 8)
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.
DVD-RW (page 8)
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. 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.
DVD VIDEO (page 10)
A disc that contains up to eight hours of moving
pictures on a disc the same diameter 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, which
is a worldwide standard 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 on the DVD.
Hard disk drive (page 2)
A hard disk drive is a whole mechanical system
that consists of disks and drive. Disks are flat,
circular, rigid plates coated with a thin magnetic
media. Magnetic heads record data on the rapidly
spinning disks, and this enables the speedy and
efficient reading and writing of data.
File (page 66)
A JPEG image recorded on a DATA CD. (File is
an exclusive definition for this recorder.) A single
file consist of a single image.
Interlace format (page 26)
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.
MPEG Audio (page 62)
International standard coding system used to
compress audio digital signals authorized by ISO/
IEC. MPEG 2, used on DVDs, conforms to up to
7.1-channel surround.
Original (page 71)
Titles actually recorded on a HDD/DVD-RW (VR
mode). Erasing original titles frees up disc space.
Playlist (page 71)
Playback information created from the actual
recordings on a HDD/DVD-RW (VR mode). A
Playlist leaves the original titles as they are, and
contains only the information needed to control
playback. A Playlist title takes up very little disc
space.
Progressive format (page 26)
Compared to the Interlace format that alternately
shows every other line of an image (field) to create
one frame, the Progressive format shows the entire
image at once as a single frame. This means that
while the Interlace format can show 25-30 frames/
50-60 fields in one second, the Progressive format
can show 50/60 frames in one second. The overall
picture quality increases and still images, text, and
horizontal lines appear sharper.
Title (page 66)
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 (page 66)
Sections of a music feature on a CD/VIDEO CD
(the length of a song).
