Chapter
Subdivision of a title on a DVD VIDEO.
A title is composed of several chapters.
Dolby Digital
This movie theater sound format is
more advanced than Dolby Surround
Pro Logic. In this format, the surround
speakers output stereo sound with
an expanded frequency range and a
subwoofer channel for deep bass is
independently provided. This format is
also called "5.1" because the subwoofer
channel is counted as 0.1 channel (since
it functions only when a deep bass effect
is needed). All six channels in this format
are recorded separately for superior
channel separation. Furthermore, since
all the signals are processed digitally, less
signal degradation occurs.
DTS
Digital audio compression technology
developed by DTS, Inc. This technology
conforms to 5.1-channel surround. The
surround channel is stereo and there
is discrete subwoofer channel in this
format. DTS provides the same 5.1
discrete channels of high quality digital
audio. The good channel separation is

to
realized because the all channel data
is recorded discrete and processed in
digital.
DVD VIDEO
A disc that contains up to 8 hours of
moving pictures even though its diameter
is the same as an 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 an 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.
