Glossary
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.
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 (44,100 times a second for 
CD audio) by an analogue-to-digital 
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. DTS surround sound 
technologies were developed by 
DTS, Inc.
Finalise
To make DVDs that have been 
recorded playable in DVD players, 
finalise DVD-RW / R and 
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.
