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 relative to its height.
Conventional TVs are 4:3 (in other words, the TV screen is
almost square); widescreen models are 16:9 (the TV
screen is almost twice as wide as it is high).
Chapter (DVD only)
Just as a book is split up into several chapters, a title on a
DVD is usually divided into chapters. See also "Title".
Component Video Output
Each signal of luminance (Y) and component (P
C ) is independent to output so that you can experience
R
picture color as it is.
Also, due to compatibility with progressive video (480p),
you can experience higher-density picture than that in
interlace (480i) mode.
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 also "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.
Finalize
To make DVD, which have been recorded on, possible to
play back in DVD players. With this unit, it is possible to
finalize DVD-RW, and DVD-R.
HDMI™ (high definition multimedia interface)
A digital interface between audio and video source. It can
transmit component video, audio, and control signal with
one cable connection.
JPEG (joint photographic experts group)
JPEG is a method of compressing still image files. You
can copy JPEG files on CD-RW/-R from a computer and
play back the files on this unit.

GLOSSARY

PCM (pulse code modulation)
The most common system of encoding digital audio,
found on CD 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".
Progressive Scan (480p)
A type of display that does not split each frame into fields,
and instead scans directly through all the scan lines of
each frame in order. Progressive scan provides less
flickering and higher image resolution than traditional
(480i) TV signals. Refer to page 78 for instructions on
selective progressive scan mode.
Region Code
/C , P /
B B R
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 which sound is measured by a specified interval
to turn into digital audio data. The numbers of sampling in
one second defines as sampling frequency. The higher
the rate, the better the sound quality.
S-Video Output
It delivers independently each signal 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. See also "Chapter".
Track
Audio CD use tracks to divide up the content of a disc.
The DVD equivalent is called a chapter. See also
"Chapter".
Video mode
Video mode is the same recording format as used on the
DVD videos you purchase in local shops. You can play
back the discs recorded in this format in most DVD
players, however it offers only limited editing. You will
need to finalize discs recorded in video mode before
playing them back on other units.
VR mode
A basic recording format for DVD-RW. VR mode offers
advanced editing, however it is playable only on VR mode
compatible unit. Finalization is recommended before
playing them back on other units.
