Analog audio
An electrical signal that directly
represents sound. Compare this
to 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 sev-
eral chapters, a title on a DVD
disc is usually divided into chap-
ters. See also Title.
Component video output
Each signal of luminance(Y) and
component(P
B/CB,PR/CR) is inde-
pendent to output so that you can
experience picture color as it is.
CPRM
(Content Protection for
Recordable Media)
CPRM is a copy protection sys-
tem with scramble system regard-
ing the recording of “copy-once”
broadcast programs (e.g. some
satellite broadcasts).
Digital audio
An indirect representation of
sound by numbers. During record-
ing, the sound is measured at dis-
crete intervals (44, 100 times a
second for CD audio) by an ana-
log-to-digital converter, generating
a stream of numbers. On playback,
a digital-to-analog converter gen-
erates an analog signal based on
these numbers. See also Sampling
frequency and Analog audio.
Dolby Digital
The system to compress digital
sound developed by Dolby
Laboratories. It offers you sound
of stereo(2ch) or multi-channel
audio (up to 5.1ch).
MP3 (MPEG Audio Layer 3)
MP3 is a method of compressing
files.You can copy MP3 files on
CD-R/RW discs from the comput-
er and play the files on this unit.
Finalize
To make DVD discs, which have
done recording, possible to play in
DVD players.With this unit, it is
possible to finalize DVD-R/DVD-
RW discs.
PCM
(Pulse Code Modulation)
The most common system of
encoding digital audio, found on
CDs and DAT. Excellent quality,
but requires a lot of data com-
pared to formats such as Dolby
Digital and MPEG audio. For com-
patibility with digital audio
recorders (CD, MD and DAT) and
AV amplifiers with digital inputs,
this unit can convert Dolby Digital
and MPEG audio to PCM. See also
Digital audio.
Playlist
From this list you can play con-
tents of a disc as your desired
order or in sequence.Also it is
allowed to search a specific scene
directly.
Regions code
Regions associate discs and play-
ers with particular areas of the
world.This unit will only play 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 which sound is measured
by a specified interval to turn into
digital audio data.The numbers of
sampling in one second defines as
sampling frequency.The higher the
rate, the better the sound quality
as possible as it is.
SAP
(Secondary Audio Program)
Sub-audio channel which is deliv-
ered separately from main-audio
channel.This audio channel is used
as an alternate in bilingual broad-
casting.
S-Video output
It delivers independently each sig-
nal of color(C) and luminance(Y)
to TV as video signals, so that
higher-quality picture will be
gained.
Title (DVD only)
A collection of chapters on DVD
disc. See also chapter.
Track
Audio CDs use tracks to divide
up the content of a disc.The DVD
equivalent is called a chapter. See
also Chapter.
