HOLE ACCUMULATION DIODE (HAD)
A CCD sensor with improved performance
in spectral response, vertical smear, and
sensitivity. The HAD sensor also introduced
electronic shuttering capability to IT type
sensors.
•Advanced HAD: Provides brilliant results
even in low-light situations due to its
greater luminance sensitivity and its wider
dynamic range which drastically improves
the signal to noise ratio. This advantage is
especially obvious for natural evening
scenes or indoor events.
•Hyper HAD: A derivative of the HAD sensor
that incorporates On Chip Lensing (OCL)
and the use of microscopic lenses
mounted over each sensing pixel. Hyper
HAD sensors with OCL have no
perceptible smear and nearly doubled
sensitivity.
I.LINK
See IEEE 1394.
ID3

can be used to support up 63 external
devices from a single port. It supports
isochronous data — delivering data at a
guaranteed rate which makes it ideal for
devices that need to transfer high levels of
data in real-time, such as video devices.
Also known as FireWire, i.LINK or Lynx.
•IEEE 1394a: Supports data rates of up to
400Mbps
•IEEE 1394b: Supports data rates of up to
800Mbps
INFOLITHIUM
Battery technology that displays remaining
charge and precise remaining recording
time in minutes on the viewfinder or LCD
screen.
INTEGRATED CIRCUIT (IC)
A complex set of electronic components
and their interconnections that are etched
or imprinted on a chip.
INTERLACE SCAN
The means by which traditional video
creates images on screen. Interlaced
scanning breaks down a single frame of
video into 2 fields, one containing the odd
numbered lines, the other containing the
even. These 2 fields are then alternately
broadcast/shown to maintain high picture
quality with limted bandwidth.
INTERMEDIATE FREQUENCY (IF)
A frequency to which a carrier frequency is
shifted as an intermediate step in
transmission or reception.
INTERVAL RECORDING
Capturing a series of images/frames at
preset intervals. Also known as Time Lapse.
•Interval Recording: Captures 3 frames at
preset intervals.
•Smooth Interval Recording: Captures 1
frame at preset intervals.

The International Standards Organisation
ergonomic requirements for flat panel
displays
JOINT PHOTOGRAPHIC EXPERTS
GROUP (JPEG)
JPEG compresses graphics of
photographic color depth better than other
file formats like GIF, and it retains a high
degree of color fidelity. This makes JPEG
files smaller and quicker to download. You
can choose how much to compress a
JPEG file, but since it is a lossy format, the
smaller you compress the file, the more
color information will be lost.
KEYSTONE CORRECTION
Keystone is a distortion of the image
caused by projecting at the wrong vertical
angle. Digital keystone correction produces
an inverse effect that cancels this distortion.
LETTERBOX
Converts widescreen content into 4:3
content by placing black bars at the top and
bottom of the picture.
LIGHT EMITTING DIODE (LED)
A diode is a semiconductor device through
which current can go in only one direction.
As a side effect, light-emitting diodes
produce either visible or infrared light and
require very little power.
LIQUID CRYSTAL DISPLAY (LCD)
A two-dimensional array of small crystals
that are normally opaque, but become
transparent when voltage is applied to
them. LCDs are often back-lit for viewing in
a dark room.
LITHIUM-ION (LI-ION)
A type of a battery composed of Lithium,
the lightest metal and the metal that has the
highest electrochemical potential. Because
of its lightness and high energy density,
Lithium-Ion batteries are ideal for portable
devices, such as phones and notebook
computers. In addition, Lithium-Ion batteries
have no memory effect and do not use
poisonous metals, such as lead, mercury or
cadmium.

added to the soundtrack for extra effect.
This track does not inherently contain all the
bass of the soundtrack.
LOW PASS FILTER (LPF)
A network of elements used to attenuate all
frequencies above a pre-determined
frequency. Frequencies below the cutoff are
passed without effect.
MAGICGATE (MG)
A copyright protection technology for
MagicGate Memory Stick and compliant

MPX
Found in analog cassette decks, it removes
non-musical high-frequency noise from
tapes during recording and eliminates
interaction with the bias frequency.
MULTI-SESSION
A feature of many recordable CD drives and
discs that enables you to add data to a CD-
ROM on different occasions. This is an
improvement over older CD-Rs, which
required you to burn all your data onto the
disc at once.
NATIONAL TRANSMISSION
STANDARDS COMMITTEE (NTSC)
"Analog video standard that delivers 525
lines at 60 fields (half-frames interlaced) per
second, and is the official standard for video
in North America; and parts of South
America and Asia.
•NTSC 3.58: The original NTSC standard.
•NTSC 4.43: A variation of NTSC where the
signal is encoded using the PAL subcarrier
frequency and chroma modulation. Also
known as PAL60.
NICAM STEREO
NICAM is a digital stereo compression
system developed by BBC engineers that
has proven to be extremely rugged,
providing high quality stereo sound even
when the signal is weak.
NIGHTSHOT
Take monochrome pictures in low-light and
no-light situations. With the flip of a switch,
the infrared NightShot mode is activated,
which defeats the flash and an infrared
picture is captured with invisible, infra-red
light. NightShot makes it possible to take
pictures or MPEG movies of sleeping
children and nocturnal wildlife in a way that is
impossible with all other cameras.
NOISE REDUCTION (NR)
The process of reducing the imperfections
in analog signal to deliver a purer video or
audio experience.
OHM

electric current (I) and resistance (R), named
for German physicist Georg Simon Ohm
(1789 to 1854).
ON SCREEN DISPLAY (OSD)
Provides clearer menu functions by using a
display to view the menu, while the controls
are on the remote control or the control unit.
OPTICAL DIGITAL
An optical digital line allows you to transfer
sound in lossless, digital quality.
OXYGEN FREE COPPER (OFC)
Improves signal transmission and
conduction.
PACKET WRITING
Packet writing is a technology that enables
the writing of data to a CD-R incrementally,
in multiple small blocks of data, rather than in
a single block (as in disk-at-once recording),
or in blocks defined by tracks (as in track-at-
once recording), the other two common
methods. Packet writing software makes it
possible for the user to save data to a CD-R
or CD-RW in the same way as it would be
saved to the hard drive or a floppy.
PAN AND SCAN
Converts widescreen content into 4:3
content by selectively zooming and
cropping portions of the widescreen picture.
Whilst completely filling a 4:3 aspect ratio
screen, 25% to 40% of the widescreen
content is lost.
PEAK MUSIC POWER OUTPUT
(PMPO)
A method of rating the power output of
speakers or amplifiers which works by
calculation of power peaks.
PERSONAL COMPUTER MEMORY
CARD INTERNATIONAL
ASSOCIATION (PCMCIA)
An organization consisting of some 500
companies that has developed a standard
for small, credit card-sized devices, called
PC Cards. Originally designed for adding
memory to portable computers, the
PCMCIA standard has been expanded
several times and is now suitable for many
types of devices. There are three types of
PCMCIA cards:
•Type I cards: Up to 3.3 mm thick, and are
used primarily for adding additional ROM or
RAM to a computer.
•Type II cards: Up to 5.5 mm thick. These
cards are often used for modem and
wireless cards.
•Type III cards: Up to 10.5 mm thick, which is
sufficiently large for portable disk drives.
PHASE-LOCKED LOOP (PLL)
An electronic circuit employed within a radio
receiver which precisely tunes it to a station
frequency and rejects interference which
might otherwise hinder this operation. The
synthesiser which tunes the radio uses a
small quartz crystal to generate a stable
reference frequency.
PICTURE IN PICTURE (PIP)
Displays a small picture from another video
source, over one corner of the main picture.
POWERBURN
Advanced buffer under-run technology that
also continues to monitor both data stream
and media to optimise disc creation.
PRECISION DRIVE
Delivers clear DVD playback. Utilising two
separate reading heads (or pickup) to read
DVD and CD recordings, playback accuracy
is superb without a complicated switching
mechanism. It compensates for minor
imperfections like the warping of discs,
minor shakes and rattles, making perfect
playback from imperfect conditions possible.
PROGRESSIVE SCAN
An alternate means to interlaced video used
to create images on screen. Progressive
scanning reproduces an entire video frame
in a single pass, from top to bottom thereby
reducing flicker, improving contrast and
producing a more film-like result.
PULSE CODE MODULATION (PCM)
An uncompressed, digitally coded
representation of an analog signal. The
waveform is sampled at regular intervals and
a series of pulses in coded form (usually
quantized) are generated to represent the
amplitude.
