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

Information stored at the end of an MP3 file. The tag can contain information about the Title/Song name, Artist, Album, Year, Comment, Genre and Track.

IEEE 1394

"A very fast data transfer standard, which 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

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.

ISO-13406-2

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.

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 products.

MICROMV

Provides up to 60 minutes of high-quality, MPEG-2 digital video footage and adds a 64-kb memory chip. The memory chip allows for a multi-search function that lets users access different sections of the tape as they would a DVD by creating thumbnail images of all of the recorded scenes on the tape.

MPX

Found in analog cassette decks, it removes non-musical high-frequency noise from tapes during recording and eliminates interaction with the bias frequency.

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 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

The relationship between voltage (V), electric current (I) and resistance (R), named for German physicist Georg Simon Ohm (1789 to 1854).

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.

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.
