Analog Audio g
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 p
The width of a TV screen relative to its height.
Older Conventional TVs are 4:3 (in other words, the TV
screen is almost square); widescreen DTV (Digital TV)
models are 16:9 (the TV screen is almost twice as wide as
it is high).
Block Noise
A distortion of digital images in the shape of blocks
caused by the application of data compression.
Chapter (HDD/DVD) p
Just as a book is split up into several chapters, a title on
HDD/DVD is usually divided into chapters. See also "Title".
Component Video Output p
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).
Digital Audio g
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 y g
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) g
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) j p g p
JPEG is a method of compressing still image files. You can
copy JPEG files from your personal computer to a disc,
and play them back on this unit.

PCM (pulse code modulation) p
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) g
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 110 for instructions on
selective progressive scan mode.
Region Code g
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 p g q
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) y
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 p
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 (HDD/DVD)
A collection of chapters on HDD/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".
