Glossary

Analog audio

An electrical signal that directly

represents sound. In contrast, digi-

tal audio can be an electrical sig-

nal, but is an indirect representa-

tion of sound. See also Digital

audio.

Aspect ratio

The width of a TV screen relative

to its height. Conventional TVs are

4:3 (in other words, the screen is

almost square); widescreen models

are 16:9 (the screen is almost

twice as wide as it is high).

Chapter

Just as a book is split up into sev-

eral chapters, a title on a DVD

disc is usually divided into chap-

ters. See also Title.

Component video output

This is a video signal format that

conveys each of three principal

colors of light (red, blue and

green) through different signal

lines.This allows the viewers to

experience picture colors as origi-

nal as it is.There are several signal

formats, including Y/PB/PR and

Y/CB/CR.

CPRM

(Content Protection for

Recordable Media)

This is a format used to record

copy-once programs. By recording

coded data on the area of DVD

discs that ordinary writing soft-

ware cannot write on, it prevents

copy-once programs from being

recorded repeatedly on different

media.

Digital audio

An indirect representation of

sound by numbers. During record-

ing, the sound is measured at dis-

crete intervals (44, 100 times a

second for CD audio) by an ana-

log-to-digital converter, generating

a stream of numbers. On playback,

a digital-to-analog converter gen-

erates an analog signal based on

these numbers. See also Sampling

frequency and Analog audio.

Dolby Digital

The system developed by Dolby

Laboratories to compress digital

sound. It offers you sound of

stereo(2ch) or multi-channel

audio (up to 5.1ch).

DTS (Digital Theater System)

DTS is a 5.1 channel surround

sound system, but it is different

from Dolby Digital.The formats

were developed by Digital Theater

System, Inc.

Finalize

To make recorded contents on

DVD discs possible to be played

back on DVD players.With this

unit, it is possible to finalize

DVD-RW/DVD-R discs.

MP3 (MPEG Audio Layer 3)

MP3 is a method of compressing

files.You can copy MP3 files on

CD-RW/-R discs from the com-

puter and play back the files on

this unit.

PCM

(Pulse Code Modulation)

PCM is a format that converts

audio into digital data. It is mainly

used for Audio CDs and DAT.This

unit can play back sounds as real-

istic as possible by converting

even compressed Dolby Digital

and MPEG audio to PCM.

Playlist

From this list you can play back

contents of a disc in your desired

order or sequence.Also it allows

to search a specific scene directly.

Progressive scan (480p)

A type of display that does not

split each frame into fields, and

instead scans directly through all

the scanlines of each frame in

order. Progressive scan provides

less flickering and higher image

resolution than traditional (480i)

TV signals. Refer to page 14 for

instructions on selective progres-

sive scan mode.

Regions code

Regions associate discs and play-

ers with particular areas of the

world.This unit will only play back

discs that have compatible region

codes.You can find the region

code of your unit by looking at

the rear panel. Some discs are

compatible with more than one

region (or all regions).

Sampling frequency

The rate which sound is measured

by a specified interval to turn it

into digital audio data.The num-

bers of sampling in one second

defines as sampling frequency.The

higher the rate, the better the

sound quality is.

SAP

(Secondary Audio Program)

Sub-audio channel which is deliv-

ered separately from main-audio

channel.This audio channel is used

as an alternate in bilingual broad-

casting.

S-Video output

It delivers independently each sig-

nal of color(C) and luminance(Y)

to TV as video signals, so that

higher-quality picture will be

materialized.

Title (DVD only)

A collection of chapters on DVD

disc. See also Chapter.

Track

Audio CDs use tracks to divide

the content of a disc.The DVD

equivalent is called a chapter. See

also Chapter.
