GLOSSARY
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
TV
screen
is
almost square); widescreen models are 16:9 (the
TV
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
is
usually
divided
into
chapters.
See
also "Title".
Component Video
Output
Each
signal
of
luminance
(Y)
and
component
(Ps/Cs,
PRI
CR)
is
independent
to
output
so
that
you can experience
picture color
as
it
is.
Also,
due
to
compatibility
with
progressive video (480p),
you can experience higher-density picture than
that
in
interlace (480i).
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".
DivX'"
DivX'"
is
a codec (compression/decompression)
that
can
compress images
to
a very small
amount
of
data.
Dolby'" Digital
The system
to
compress digital sound developed by
Dolby Laboratories. It offers you sound
of
stereo(2ch)
or
multi
channel audio.
DTS'"
(Digital Theater System)
DTS
is
a
multi
channel surround sound system.
By
connecting
to
DTS
decoder you can enjoy dynamic and
realistic sound like movie theatre.
DTS
surround sound
technologies were developed by
DTS,
Inc.
Finalize
To make
DVD,
which have been recorded on, possible
to
play back in DVD players.
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.
JPEG
ijoint photographic experts group)
JPEG
is
a
method
of
compressing still image files. You can
copy
JPEG
files on CD-RW/-R
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 from the
computer
and play back
the
files on this unit.
PCM (pulse code modulation)
The
most
common
system
of
encoding digital audio,
found
on
CD
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".
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. Refer
to
page 94
for
instructions on
selective progressive
scan
mode.
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 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.
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.
See
also "Chapter".
