Section of a music piece or an image on a data 
CD containing MP3 audio tracks or JPEG files.

Subdivision of a title on a DVD. A title is 
composed of several chapters.

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

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 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.

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.

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.

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.

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.

A JPEG image recorded on a DATA CD or a 
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.

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,
