DVD VIDEO (page 7)
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 VIDEO 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 Dolby Digital as well as in PCM, 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 VIDEO.

conforms to up to 7.1-channel surround.
Parental Control (page 78)
A function of the DVD VIDEO used to limit
playback of the disc according to the age of
the user and the limitation level in each
country. The limitation varies from disc to
disc; when it is activated, or playback is
completely prohibited, violent scenes are
skipped or replaced with other scenes, etc.
Region Code (page 7)
This system is used to protect copyrights. A
region number is allocated on each DVD
player or DVD disc according to the sales
region. Each region code is shown on the
player as well as on the disc packaging. The
player can play the discs that match its region
code. The player can also play discs with the
mark. Even when the region code is not
shown on the DVD, the region limit may still
be activated.
