DVD VIDEO (page 8)
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 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. 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 8)
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 (page 50, 53)
A JPEG image recorded on a DATA CD
(“File” is an exclusive definition for this
player.) A single file consist of a single
image.
Film based software, Video based
software (page 66)
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.
Video Index (VIDEO CD) (page 14)
A number that divides a track into sections to
easily locate the point you want on a VIDEO
CD. Depending on the disc, no index may be
recorded.
Normal (Interlace) format (page 66)
Normal (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.
Progressive format (page 66)
Compared to the Normal (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 Normal (Interlace) format can show 30
frames/60 fields in one second, the
Progressive format can show 60 frames in one
second. The overall picture quality increases
and still images, text, and horizontal lines
appear sharper. This player is compatible
with the 480 progressive format.
Progressive JPEG (page 56)
Progressive JPEGs are used mostly on the
internet. They are different from other JPEGs
in that they “fade in” gradually instead of
being drawn from top to bottom when
displayed on a browser. This lets you view the
image while it is being downloaded.
Scene (page 11)
On a VIDEO CD with PBC (playback
control) functions, the menu screens, moving
pictures and still pictures are divided into
sections called “scenes.”
