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
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 (PB/CB, PR/
C
R) 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).
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+R, DVD-RW, and DVD-R.
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.
MP3 (MPEG audio layer 3)
MP3 is a method of compressing files. You can copy MP3
files on CD-RW/-R from the computer and play back the
files on this unit.
PBC (playback control) (video CD only)
This function enables you to play back interactive
software using a menu screen. See also “Video CD”.
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 (525p/480p)
A type of display that does not split each frame into
fields, and instead scans directly through all the scanlines
of each frame in order. Progressive scan provides less
flickering and higher image resolution than traditional
(525i/480i) TV signals. Refer to page 103 for instructions
on selective progressive scan mode.
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 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.
SAP (secondary audio program)
Sub-audio channel which is delivered separately from
main-audio channel. This audio channel is used as an
alternate in bilingual broadcasting.
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 CD
A digital format for store video data in compact disc.
