Glossary

Analog audio

An electrical signal that directly represents

sound. In contrast, digital audio which can be

an electrical signal,but is an indirect repre-

sentation 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 several

chapters,a title on a DVD disc is usually

divided into chapters. 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 experi-

ence picture colors as original as it is.

There are several signal formats,including

Y / PB/ PRand 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 writ-

ing software 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 recording, the sound

is measured at discrete intervals (44,

100 times a second for CD audio) by

an analog-to-digital converter,generat-

ing a stream of numbers. On playback,

a digital-to-analog converter generates

an analog signal based on these num-

bers. 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.

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/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 computer 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 realistic as possible by

converting even compressed Dolby

Digital and MPEG audio to PCM.

Playlist

From this list you can play back con-

tents 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.

See page 17 for instructions on selec-

tive progressive scan mode.

Regions code

Regions associate discs and players with

particular areas of the world. This unit

will only play back discs that have com-

patible 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 numbers of sampling in

one second defines as sampling fre-

quency.The higher the rate, the better

the sound quality is.

SAP (Secondary Audio Program)

Sub-audio channel which is delivered sep-

arately from main-audio channel. This

audio channel is used as an alternate in

bilingual broadcasting.

S-Video output

It delivers independently each signal of

color(C) and luminance(Y) to TV as video

signals,so that higher-quality picture will

be materialised.

Title (DVD only)

A collection of chapters on DVD disc.
