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 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.

while discs created in VR (Video Recording)
mode allow the contents to be programmed or
edited.
