DVD VIDEO
A disc that contains up to 8 hours of moving
pictures even though its diameter is the same as
a 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 a 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 is 9.4 GB, and a
dual-layer and double-sided DVD VIDEO is
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.
