Glossary

Analog audio

An electrical signal that directly repre-

sents sound. In contrast, digital audio

which can be an electrical signal, but

is an indirect representation 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 con-

veys each of three principal colors of

light (red, blue and green) through

different signal lines. This allows the

viewers to experience picture colors

as original as it is. There are several

signal formats, including Y/P

and

Y/C

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 (up to 5.1ch).

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+R/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 computer and play back

the files on this unit.

PBC (Playback Control)
(Video CD only)

This function enables you to play back

interactive software using a menu

screen. See also Video CD.

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.

Progressive Scan (525p/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 tradi-

tional (525i/480i) TV signals. Refer to

page 71 for instructions on selective

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

compatible region codes. You can find

the region code of your unit by looking

at the rear panel. Some discs are com-

patible 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

separately from main-audio channel.

This audio channel is used as an alter-

nate 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 pic-

ture will be materialized.

Title (DVD only)

A collection of chapters on DVD disc.
