DivX

®

Digital video technology created by
DivXNetworks, Inc. Videos encoded with DivX
technology are among the highest quality with a
relatively small file size.

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” 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.

File

DivX video on a DATA CD/DATA DVD.
(“File” is an exclusive definition for this
system.) A single file consists of a single image
or movie.
