Glossary
Analog audio
An electrical signal that directly represents
sound. In contrast, digital audio which can
be an electrical signal, but is an indirect rep-
resentation 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
experience 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
writing software cannot write on, it pre-
vents 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 inter-
vals (44,
100 times a second for CD
audio) by an analog-to-digital convert-
er, generating a stream of numbers.
On playback, a digital-to-analog con-
verter generates an analog signal
based on these numbers. 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 possi-
ble to finalize 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.
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 possi-
ble 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 (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 pro-
vides less flickering and higher image
resolution than traditional (525i/480i)
TV signals. Refer to page
15 for instruc-
tions 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 com-
patible region codes.You can find the
region code of your unit by looking at
the rear panel. Some discs are compati-
ble with more than one region (or all
regions).
Sampling frequency
The rate which sound is measured by
a specified interval to turn it into digi-
tal audio data.The numbers of sam-
pling in one second defines as sam-
pling frequency.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 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 pic-
ture will be materialized.
Title (DVD only)
A collection of chapters on DVD disc.
See also chapter.
Track
Audio CDs use tracks to divide the
content of a disc.The DVD equivalent is
called a chapter. See also Chapter.
