Glossary
Album
Section of a music piece or an image on a data CD
containing MP3 audio tracks or JPEG files.
Chapter
Subdivision of a title on a DVD. A title is
composed of several chapters.
Digital Cinema Auto Calibration (D.C.A.C.)
Digital Cinema Auto Calibration was developed
by Sony to automatically measure and adjusts the
speaker settings to your listening environment in a
short period of time.
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 movie theatre 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” with the
subwoofer channel designed as the 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.
Dolby Pro Logic II
Dolby Pro Logic II creates five full-bandwidth
output channels from 2 channel sources. This is
done using an advanced, high-purity matrix
surround decoder that extracts the spatial
properties of the original recording without adding
any new sounds or tonal colorations.
DTS
Digital audio compression technology developed
by Digital Theater Systems, Inc. This technology
conforms to 5.1-channel surround. This format
comprises of stereo rear channel 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 due to the all channel data being
recorded discretely and processed in digitally.
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
a worldwide standard 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 processes
allocated data 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.
DVD-RW
A DVD-RW is a recordable and rewritable disc
that is the same size as a DVD VIDEO. The DVD-
RW has two different 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.
DVD+RW
A DVD+RW (plus RW) is a recordable and
rewritable disc. DVD+RWs use a recording
format that is comparable to the DVD VIDEO
format.
