English

JPEG:

(Joint Photographic Experts Group)
JPEG is a method of compressing

still image files. You can copy JPEG

files on CD-RW / R or DVD+R / RW

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 or DVD+R / RW discs from a

computer and play back the files on

this unit.

Multichannel:
DVD is specified to have each sound

track constitute one sound field.

Multichannel refers to a structure of

sound tracks having three or more

channels.

Parental control:
A function of the DVD to limit playback

of the disc by the age of the users

according to the limitation level in

each country. The limitation varies

from disc to disc; when it is activated,

playback will be prohibited if the

software’s level is higher than the

user-set level.
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.
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.

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

it is 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)

AUDIO OUT jacks:
Jacks on the back of the DVD System

that send audio to another system (TV,

Stereo, etc.)

Bit rate:
The amount of data used to hold a given

length of music; measured in kilobits

per seconds, or kbps. Or, the speed at

which you record.Generally, the higher

the bit rate, or the higher the recording

speed, the better the sound quality.

However, higher bit rates use more

space on a disc.

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.

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 astream of numbers.

On playback, a digital-to-analogue

converter

generates an analogue signal based

on these numbers. See also Sampling

frequency and Analogue audio.

Disc menu:
A screen display prepared for allowing

of selection of images, sound, subtitle,

multi-angles etc. recorded on the DVD.
Dolby

Digital:

A system developed by Dolby

Laboratories that compresses digital

sound. It works with stereo (2ch) or

multi-channel audio.

HDMI

(High Definition Multimedia Interface)

A digital interface between audio

and video source. It can transmit

component video, audio and control

signal with one cable connection.

Title:
(DVD)

A collection of chapters on a DVD.
