Chapter
Sections of a picture or a music piece on a DVD
that are smaller than titles. A title is composed of
several chapters. Each chapter is assigned a
chapter number enabling you to locate the
chapter you want.
Dolby Digital
This sound format for movie theaters 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
to realize superior channel separation.
Furthermore, since all the signals are processed
digitally, less signal degradation occurs.
DTS
Digital audio compression technology that the
Digital Theater Systems, Inc. developed. This
technology conforms to 5.1-channel surround.
The surround channel is stereo and there is
discrete sub woofer channel in this format. DTS
provides the same 5.1 discrete channels of high
quality digital audio. The good channel
separation is realized because the all channel
data is recorded discrete and processed in
digital.
DVD
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, at 4.7 GB (Giga Byte), is 7 times
that of a CD. Furthermore, the data capacity of a
dual-layer and single-sided DVD is 8.5 GB, a
single-layer and double-sided DVD 9.4 GB, and
a dual-layer and double-sided DVD 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 of its original size. The DVD also
uses the 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.
File
Section of a picture on a data CD containing
JPEG image files.
Film based software, Video based
software
DVDs can be classified as Film based or Video
based software. Film based DVDs contain the
same images (24 frames per second) that are
shown at movie theaters. Video based DVDs,
such as television dramas or sit-coms, displays
images at 30 frames (or 60 fields) per second.
