Section of a music or picture piece on 

a DATA CD or DATA DVD containing 

MP3 audio tracks, JPEG image files.

Subdivision of a title on a DVD VIDEO. 

A title is composed of several chapters.

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.

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.

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. 

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 VIDEO. 

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.
