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 Digital audio.
■ Aspect ratio
The width of a TV screen relative 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 several chapters, a
title on a DVD disc is usually divided into chapters.
See Title.
■ Component video output
Each signal of luminance(Y) and component(Pb/
Cb, Pr/Cr) is independent to output so that you can
experience picture color as it is.
Also, due to compatibility with progressive video
(525p/480p), you can experience higher-density
picture than that in interlace (525i/480i).
■ CPRM
(Content Protection for Recordable Media)
CPRM is a copy protection system with scramble
system regarding 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 converter, generating
a stream of numbers. On playback, a digital-to-
analog converter generates an analog signal
based on these numbers. See Sampling frequency
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.
■ DTS (Digital Theater System)
DTS is a 5.1 channel surround sound system, but
it is different from Dolby Digital. The formats were
developed by Digital Theater System, Inc.
■ Finalize
To make DVD discs, which have been recorded
on, possible to play in DVD players. With this unit,
it is possible to finalize DVD-R/DVD-RW discs.
■ MP3 (MPEG Audio Layer 3)
MP3 is a method of compressing files. You can
copy MP3 files on CD-RW/R discs from the
computer and play 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)
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 Digital audio.
