Glossary

Analogue audio
An electrical signal that directly

represents sound. In contrast,

digital audio can also 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

(i.e., the screen is almost square).

Widescreen models are 16:9 (the

screen is almost twice as wide as its

height).

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
Each signal of luminance(Y) and

component (P

, P

) is

independent to output so that you

can experience picture colour as it

is.

Also, due to compatibility with

progressive video (625p/525p), you

can experience higher-density

picture than that in interlace (625i/

525i).

CPRM

(Content Protection for

Recordable Media)
CPRM is a scrambling copy

protection system for the protection

of “copy-once” broadcast

programmes (e.g. some satellite

broadcasts).

Digital audio
An indirect representation of sound

using numbers. During recording,

the sound is measured at discrete

intervals (44,100 times a second for

CD audio) by an analogue-to-digital

converter, generating a stream of

numbers. On playback, a digital-to-

analogue converter generates an

analogue signal based on these

numbers. See also Sampling

frequency and Analogue audio.

Dolby Digital
A system developed by Dolby

Laboratories that compresses

digital sound. It works with stereo

(2ch) or multi-channel audio.

DTS

(Digital Theater System)
DTS is a multi channel surround

sound system. By connecting to

DTS decoder, you can enjoy

dynamic and realistic sound like

movie theatre. DTS surround sound

technologies were developed by

DTS, Inc.

Finalise
To make DVDs that have been

recorded playable in DVD players. It

is possible to finalise DVD-RW/-R

and DVD+RW/+R discs with this

unit.

INSTANT SKIP
This unit can skip TV commercials

during DVD Video playback. Once

[INSTANT SKIP] is pressed, the

start point will be set forward 30

seconds and playback resume

automatically. (You can press

[INSTANT SKIP] up to 6 times.)

JPEG

(Joint Photographic Experts

Group)
JPEG is a method of compressing

still image files. You can copy JPEG

files on CD-RW/-R discs from a

computer and play back the files on

this unit.

MP3

(MPEG Audio Layer 3)
MP3 is a method of compressing

files. You can copy MP3 files on

CD-RW/-R discs from a computer

and play back the files on this unit.

PBC (Video CD only)

(Playback Control)
This function enables you to play

back interactive software using a

menu screen. See also Title.

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

contents of a disc in your desired

order or in sequence. It is also

possible to directly search for a

specific scene.

Progressive Scan (625p/525p)
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 (625i/

525i) TV signals. Refer to pages 19

and 69 for instructions on the

Progressive Scan mode selection.

Region 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 on the rear

panel. Some discs are compatible

with more than one region (or all

regions).

Sampling frequency
The rate at which sound is

measured by a specified interval to

turn it into digital audio data. The

number of samples in one second is

defined as the sampling frequency.

The higher the rate is, the better the

possible sound quality.

S-Video output
Video is output as the individual

signals of colour(C) and

luminance(Y), so a higher-quality

picture will be displayed.

Title
(DVD)

A collection of chapters on a DVD.
