Frequently Asked Questions
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
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(Pb/Cb, Pr/Cr) is
independent to output so that you
can experience picture color as it is.
Also, due to compatibility with
progressive video (525p/480p),
you can experience higher-density
picture than that in interlace
(525i/480i).
CPRM
(Content Protection for
Recordable Media)
CPRM is a copy protection system
with scramble system regarding
the recording of “copy-once”
broadcast programs (e.g. some
satellite broadcasts).
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, generating a
stream of numbers. On playback,
a digital-to-analog converter
generates 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.
Finalize
To make DVD discs, which have
been recorded on, possible to play
in DVD players. With this unit, it is
possible to finalize DVD-R/DVD-
RW 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 the files on this unit.
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 compared
to formats such as Dolby Digital
and MPEG audio. For compatibility
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
contents of a disc as your desired
order or in sequence. Also it is
allowed 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
provides less flickering and higher
image resolution than traditional
(525i/480i) TV signals. Refer
to page 13 for instructions on
selective Progressive Scan mode.
Regions code
Regions associate discs and
players 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
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
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.
–– Can I record to CD-R/RW?
No, this unit records only DVDs.
–– Can I play DVD-Video that is bought in another country?
Possible when the region code of the disc is 1 and All.
–– Is this unit JPEG compatible?
No.
–– Can I connect the unit to my PC?
No, you cannot control the unit by PCs.
