Album
Section of a music or picture piece on
a DATA CD or DATA DVD containing
MP3 audio tracks, JPEG image les.
Chapter
Subdivision of a title on a DVD VIDEO.
A title is composed of several chapters.
Dolby Digital
is 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. is format is
also called “5.1” because the subwoofer
channel is counted as 0.1 channel (since
it functions only when a deep bass eect
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 eater Systems, Inc.
developed. is technology conforms
to 5.1-channel surround. e 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. e 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.
e 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.
e picture data uses the MPEG 2
format, one of the worldwide standards
for digital compression technology. e
picture data is compressed to about 1/40
of its original size. e DVD VIDEO
also uses variable rate coding technology
that changes the data to be allocated
according to the status of the picture.
e 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.
DVD-RW
A DVD-RW is a recordable and
rewritable disc that is the same size as
a DVD VIDEO. e DVD-RW has two
dierent modes: VR mode and Video
mode. DVD-RWs created in Video
mode have the same format as a DVD
VIDEO, while discs created in VR (Video
Recording) mode allow the contents to
be programmed or edited.
