Glossary
Album
Section of a music or picture piece on
a DATA CD or DATA DVD containing
MP3 audio tracks, JPEG image files or
DivX image file.
Chapter
Subdivision of a title on a DVD VIDEO.
A title is composed of several chapters.
DivX ®
Digital video technology created by
DivX, Inc. Videos encoded with DivX
technology are among the highest quality
with a relatively small file size.
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
subwoofer 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 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.
