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 is rela-
tive 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".
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 recording, the sound is
measured at discrete intervals
(44,100 times a second for CD
audio) by an analog-to-digital con-
verter, generating a stream of
numbers. On playback, a digital-
to-analog converter generates an
analog signal based on these
numbers. See also "Sampling fre-
quency" 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
6 channels (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
been recorded on, possible to
play in other 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 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 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 sound rate is measured by a
specified interval to turn into digi-
tal 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)
Second-audio channel delivered
separately from main-audio chan-
nel. 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".
