DVD VIDEO
A disc that contains up to 8 hours of
moving pictures even though its diameter
is the same as an AUDIO CD. The data
capacity of a single-layer and single-
sided DVD VIDEO, at 4.7 GB (Giga
Byte), is 7 times that of an AUDIO CD.
Furthermore, the data capacity of a dual-
layer and single-sided DVD VIDEO is
8.5 GB, a single-layer and double-sided
DVD VIDEO 9.4 GB, and a dual-layer
and double-sided DVD VIDEO 17 GB.
The picture data uses the MPEG 2
format, one of the worldwide standards
for digital compression technology. The
picture data is compressed to about 1/40
of its original size. The DVD VIDEO
also uses variable rate coding technology
that changes the data to be allocated
according to the status of the picture.
The audio data is recorded in Dolby
Digital as well as in PCM, allowing you to
enjoy more realistic audio presence.
Furthermore, various advanced functions
such as the multi-angle, multilingual, and
Parental Control functions are provided
with the DVD VIDEO.
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

image file, DivX and MPEG4 video file
(MHC-GZR33Di only) recorded on a
DATA CD, DATA DVD or USB device.
("File" is an exclusive definition for this
system.)
Film based software, Video based
software
DVD VIDEOs can be classified as Film
based or Video based software. Film

DVD VIDEOs, such as television dramas
or sitcoms, display images at 30 frames
(or 60 fields) per second.
