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.
A DVD-RW is a recordable and rewritable
disc that is the same size as the DVD VIDEO.
The DVD-RW has two different modes: VR

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.
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.
Film based software, Video based

dramas or sit-coms, displays images at 30
frames (or 60 fields) per second.
HDMI (High-Definition Multimedia
Interface)
HDMI is an interface that supports both video
and audio on a single digital connection. The
HDMI connection carries standard to high
definition video signals and multi-channel
audio signals to AV components such as
HDMI equipped TVs, in digital form without
degradation.
Since the video signals are compatible with
the current DVI (Digital Visual Interface)
format, HDMI jacks can be connected to DVI
jacks by way of an HDMI-DVI converter
cord. The HDMI specification supports
HDCP (High-bandwidth Digital Contents
Protection), a copy protection technology that
incorporates coding technology for digital
video signals.
ID3 tag

Index (CD/Super Audio CD)/Video Index
(VIDEO CD) (page 9, 13, 48)

Normal (Interlace) format (page 77)
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.
