DVD stands for Digital Versatile Disc. Due to wide spreading of this disk as a media for high-quality video distribution, DVD is often called Digital Video Disc. But most people just use the abbreviation - DVD without specifying what V is. A DVD disc and a CD disc look the same (both 120mm diameter). But that's the end of the "sameness". It's essentially a bigger (not in size, but capacity), faster CD that can hold cinema-like video, better-than-CD audio, and computer data. DVD aims to encompass home entertainment, computers, and business information with a single digital format, eventually replacing audio CD, videotape, laserdisc, CD-ROM, and perhaps even video game cartridges. DVD has widespread support from all major electronics companies, all major computer hardware companies, and all major movie and music studios. With this unprecedented support, DVD has become the most successful consumer electronics product of all time in less than three years of its introduction.

DVD glossary

Nanometer (nm)

One thousandth of one micrometer or 0.0394 microinches. Equivalent to 10 Angstroms (Å).

Non-Return-to-Zero (NRZ)

Bi-level digital code in which one level represents a binary ONE and the other level represents a binary ZERO.

Non-Return-to-Zero-Inverted (NRZ-I)

Bi-level digital code in which the levels are changed by a binary NRZ ONE and remain unchanged by an NRZ ZERO.

NPR

Non-Photoresist Mastering method using a Laser Beam Recorder that employs an ablative process to write onto a dye layer supported by a polished, optically flat glass substrate.

NTSC

National Television Systems Committee organized by the Electronic Industries Association for the development of NTSC commercial television standards used in the United States and also Canada, Japan, and other countries. Black-and-white TV uses a scanning system of 525 lines at 60 fields per second. Color uses 525 lines at 59.94 fields per second with a 3.58 MHz color subcarrier.

Numerical Aperture (NA)

Resolution or "spot" size of a lens. A small spot is produced by a lens having a high numerical aperture achieved using a large physical aperture and/or a short focal length. NA is equal to one-half of the reciprocal of the f-stop.

Native resolution
The resolution at which the video file was captured.

NTSC
NTSC stands for National Television System Committee, which devised the NTSC television broadcast system in 1953. The NTSC standard has a fixed vertical resolution of 525 horizontal lines stacked on top of each other, with varying amounts of 'lines' making up the horizontal resolution, depending on the electronics and formats involved. There are 59.94 fields displayed per second. A field is a set of even lines, or odd lines. The odd and even fields are displayed sequentially, thus interlacing the full frame. One full frame, therefore, is made of two interlaced fields, and is displayed about every 1/30 of a second.

Numerical Aperture (NA)
A number that represents the lens aperture of a laser pick-up device. The numerical aperture is a unitless measure of the light gathering capacity of the lens system and determines its resolving power and depth of field. A vacuum has NA of 1.0 by definition. The higher the number, the better.

NUON
NUON is the new media processor made by the VM Labs. NUON enhances the passive elements of digital video products such as DVD Players, digital set top boxes and digital satellite receivers, and transforms them into compelling interactive video entertainment systems. The NUON technology allows hardware manufacturers to replace their current media processors with a programmable, flexible solution to make movies better, bring music to the big screen, Internet access and games to the DVD Player.
