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 / P
B / 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 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.
See also chapter.
Track
Audio CDs use tracks to divide the con-
tent of a disc. The DVD equivalent is
called a chapter. See also Chapter.
WMA
WMA is the audio file compressing
technology developed by Microsoft.
You can copy WMA files on CD-RW /
R discs from a computer and play them
back on this unit.
