encoded information together with FM
signals. RDS makes tuning simpler because
it can display the name of a station
transmitting an RDS signal, and it will find the
strongest signal for this station automatically.

•Program Service (PS): The station name,

up to 8 characters. 

•Traffic Announcement (TA): Allows the

radio to search for travel information and
switch to the tuned station automatically
during a traffic announcement. 

•Alternative Frequency (AF): Allows the

automatic selection of stronger signals
where more than one exists for the same
station.

•Enhanced Other Network (EON): This

service allows automatic switching to
another station for the duration of a traffic
announcement; this switching is only
possible within the same network.

Any frequency within the electromagnetic
spectrum associated with radio wave
propagation. When an RF current is supplied
to an antenna, an electromagnetic field is
created that then is able to propagate
through space. Many wireless technologies
are based on RF field propagation.

Memory hardware that can be used by
programs to perform necessary tasks while
the computer is on; an integrated circuit
memory chip allows information to be
stored or accessed in any order and all
storage locations are equally accessible.

An image capture setting that records the
CCD image sensor's raw data (without
interpolation or electronic conversions
applied) that allows the user to control and
change recording parameters post shot
including colour depth, ISO setting, white
balance, saturation, colour bit depth and so
on.

Memory hardware that allows fast access
to permanently stored data but prevents
addition to or modification of the data.

A technology where all signals are
processed digitally, regardless of source:
minimising loss of signal degradation and
resulting in highly accurate image
reproduction.

A standard for serial communication which
defines the voltages that are used and the
pattern of voltage changes. It is electrically
unbalanced, meaning that the voltage
change on one wire is not balanced by an
equal and opposite change on another. This
makes the scheme simple to implement,
but less robust than other standards.

A method of rating the power output of
speakers or amplifiers. In contrast to Peak
Music Power Output, Root Mean Square
works through a mean averaging of the
components output. This rating provides a
far more accurate impression of the actual
performance.

Enhance your music compilation even after
the recording is completed. Record level
control allows changes to the recorded
volume, meaning that difference in volume
between different songs can be easily
corrected. Record fade in/out feature, on
the other hand, allows music fading
transition to be performed in 0.1 second
steps, up to 15 seconds in length.

This feature works alongside Cinema Studio
Reverberation to "relocate" the front
speakers behind the screen, as they would
be in a real cinema. The result is a larger
listening space and a truer realisation of the
theatre sound experience.

Analog video standard that delivers 625
lines at 50 fields (half-frames, interlaced) per
second.  Once common in Europe and
Africa, many countries that formerly
adopted SECAM have now switched to
PAL.

See ESP.

The collection of radio bands ranging from
2300kHz through to 27.41MHz.

Image compensation (keystone correction)
technology that allows the projector to be
positioned off-centre in both vertical and
horizontal planes.

The ratio of the desired signal level to the
level of unwanted noise.

A fully digital amplifier that enjoys excellent
efficiency in processing sound signals as
well as minimising any loss during idling
periods. It is also extremely frugal in energy
consumption due to the absence of analog
switches. The design and packaging of
amplifiers can be further refined to produce
high quality, high power units that reside
within an even smaller chassis.

Short signal paths between circuit sections
reduce noise and improve gain, ensuring a
stable and reliable tuner performance with
excellent audio quality. High-quality circuit
elements improve inter modulation
distortion and sensitivity.

Automatically controls the intermediate
frequency bandwidth in the FM band,
reducing sound interference.

Drawing from Sony's wealth of experience
in battery technology, Stamina technology
delivers longer operating times.

•480i: Standard Definition NTSC signal - 480

lines, interlace scan with 4:3 aspect ratio.

•576i: Standard Definition PAL signal - 576

lines, interlace scan with 4:3 aspect ratio.

The standard VHS recording time of PAL or
NTSC signals.

A type of speaker used to enhance bass
response in an audio or home theatre
system. It contains a woofer (or woofers) in
an independent enclosure. Subwoofers are
generally intended to cover the range below
200Hz and can extend down to 20Hz or
below. They lend weight to the overall
sound and presentation of a system by
providing extended bass response and low-
frequency impact which can be felt
physically, but is inaudible to the human ear,
especially on action movie soundtracks.
Due to non-directional nature of this bass
sound, a subwoofer can be positioned
almost anywhere in a normal room.

An alternative to the DVD-Audio format that
is designed to play on audio CD players and
Super Audio CD players by comprising two
layers: one with CD-Audio the other with
high quality audio. The audio encoding used
is Direct Stream Digital (DSD).

Technologies available do deliver excellent
picture quality.

An SVGA display has 800 horizontal pixels
by 600 vertical pixels, giving it a total display
resolution of 480,000 individual pixels.

Separated video. Offers improved picture
quality over composite video signals by
separating the picture signal into colour and
brightness information. 

An audio-visual connection type, typically
used to connect a television and other video
components primarily used in Europe. The
SCART cable can have up to 21 active pins
and can carry audio, video and control
signals. It was developed by the French
company Peritel.

One of the most widely supported file
formats for storing lossless, bit-mapped
images on personal computers.

A group of text pages transmitted with the
normal TV signal that can be read using a TV
that has a teletext function. First regular
teletext transmissions were from BBC in
Great Britain in the 1974.

The picture aspect ratio that approximates
that of 70mm film.

Memorises several seconds of unrecorded
data. This function automatically adds a
missed beginning e.g. of a radio program
that you may have wanted to record. 

A standard set in 1991. It is even more
stringent than MPR II, especially for
alternating electric fields. Not only are the
permitted field levels reduced compared
with MPR II, but the measuring distance is
reduced as well.

•TCO'95: Includes ergonomic and ecologic

requirements.

•TCO'99: Further expends the ergonomic

and ecologic requirements.

The amount of undesirable harmonics
present in an output audio signal expressed
as a precentage. The lower the percentage
the better.

The CD-ROM disc is created, writing a track
at a time; allowing for additional data (tracks)
to be added at a later time.

A technology from SRS Laboratory that
creates a broad, fully immersive sound
image within the listening area that wraps
around the listener's head regardless of
seating position. 

A loudspeaker driver designed to handle
high frequency (treble) signals.

A UXGA display has 1600 horizontal pixels by
1200 vertical pixels, giving it a total display
resolution of 1,920,000 individual pixels.

Allows connection via USB terminal to a PC
and broadcast live video with audio, edit
images, capture still images or play back
recorded video scenes.

Continually monitors the balance between
the current and voltage amplification stages
in an amplifier, thereby reducing distortion
even at high volume levels.

A mode that only scans the lines within the
picture area when widescreen aspect ratio
content is on the screen. This optimises
picture quality by not utilising scan lines for
the blank area at the top and bottom of the
screen.

A VGA display has 640 horizontal pixels by
480 vertical pixels, giving it a total display
resolution of 307,200 individual pixels.

Overcomes one of the fundamental
challenges in accurately representing
theatre sound in a confined space. Using 3D
processing technology, it creates five pairs
of "virtual" surround speakers from the
existing rear speakers (or if unavailable the
two front speakers). "Pitched" 25 to 35
degrees overhead, these virtual speakers
create sound depth and scale, delivering a
more realistic, spacious surround sound
experience.

Voice-controlled recording on dictating
machines.

The standard unit of electric potential. It is
defined as the amount of electrical potential
between two points on a conductor carrying
a current of 1 ampere while 1 watt of power
is dissipated between the two points.

A unit of measurement of the power of an
audio signal.

Unit of power. More watts mean more
power, but how loud a system sounds also
depends on speaker sensitivity and room
size.

The ability of a camera to adjust the color
balance of a picture to compensate for the
ambient lighting.

Conventional MiniDisc playback is done with
16-bit signal processing, WBS technology
increases the rate to 18-bit or higher. This
results in more accurate playback of even
subtle sound signals, and greatly improves
the signal to noise ratio.
