Analogue audio
An electrical signal that directly
represents sound. In contrast,
digital audio can also 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 (i.e., the screen is almost
square). Widescreen models are
16:9 (the screen is almost twice
as wide as its height).
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.
CM SKIP
This unit can skip TV commercials
during DVD Video playback.
Once [CM SKIP] is pressed, the
start point will be set forward 30
seconds and playback resume
automatically. (You can press
[CM SKIP] up to 6 times.)
CPRM
(Content Protection for
Recordable Media)
CPRM is a scrambling copy
protection system for the
protection of “copy-once”
broadcast programmes (e.g.
some satellite broadcasts).
Digital audio
An indirect representation of
sound using numbers. During
recording, the sound is measured
at discrete intervals (44 or 100
times a second for CD audio) by
an analogue-todigital converter,
generating a stream of numbers.
On playback, a digital-to-
analogue converter generates an
analogue signal based on these
numbers. See also Sampling
frequency and Analogue audio.
Dolby Digital
A system developed by Dolby
Laboratories that compresses
digital sound. It works with stereo
(2ch) or multi-channel audio.
DTS
(Digital Theater System)
DTS is a Multi-channel surround
sound system, but it is different
from Dolby Digital. Both formats
were developed by Digital
Theater Systems, Inc.
Finalise
To make DVDs that have been
recorded playable in DVD players.
It is possible to finalise DVD-RW/-R
discs with this unit.
JPEG
(Joint Photographic Experts
Group)
JPEG is a method of compressing
still image files. You can copy
JPEG files on CD-RW/-R discs
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 discs from a computer
and play back the files on this
unit.
PBC (Video CD only)
(Playback Control)
This function enables you to play
back interactive software using a
menu screen. See also Title.
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 possible
by converting even compressed
Dolby Digital and MPEG audio to
PCM.
Playlist
From this list you can play back
contents of a disc in your desired
order or in sequence. It is also
possible to directly search for a
specific scene.
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 at which sound is
measured by a specified interval
to turn it into digital audio
data. The number of samples
in one second is defined as the
sampling frequency. The higher
the rate is, the better the possible
sound quality.
S-Video output
Video is output as the individual
signals of colour(C) and
luminance(Y), so a higher-quality
picture will be displayed.
Title
(DVD)
A collection of chapters on a
DVD. See also chapter.
(Video CD)
The contents of a Video CD.
When playing back a Video CD
with the PBC function, the Title
menu will appear automatically.
Track
Audio CDs and Video CDs use
tracks to divide the contents of a
disc. The DVD equivalent is called
a chapter. See also Chapter.
