Additional Information
DVD (page 6)
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.
