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.
