Dolby Digital (page 78)
Digital audio compression technology developed
by Dolby Laboratories. This technology conforms
to multi-channel surround sound. The rear channel
is stereo and there is a discrete subwoofer channel
in this format. Dolby Digital provides the same
discrete channels of high quality digital audio
found in “Dolby Digital” theater surround sound
systems. Good channel separation is realized
because all of the channel data is recorded
discretely, and little deterioration occurs because
all channel data processing is digital.
DTS (page 78)
Digital audio compression technology by Digital
Theater Systems, Inc. This technology conforms
to multi-channel surround sound. The rear channel
is stereo and there is a discrete subwoofer channel
in this format. DTS provides the same discrete
channels of high quality digital audio.

RW has two different modes: VR mode and Video
mode. DVDs created in Video mode have the

DVD VIDEO (page 30)
A disc that contains up to eight hours of moving
pictures on a disc the same diameter 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, which
is a worldwide standard 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 on the DVD.
