LUMINANCE
The signal representing the measurable intensity (comparable to brightness) of an electronic image when the image is
represented as separate
chrominance
and
luminance
. Luminance also expresses the light intensity of a diffuse source as
a function of its area; measured in lumens or candles per square foot (1 lumen per square foot = 1
foot-lambert
).
SMPTE RP 98 calls for a luminance of 12 to 22 footlamberts for theatre screens. Refer to
Foot-Lambert
.
LUX
The amount of visible light per square meter incident on a surface.
1 lux = 1 lumen/square meter = 0.093 foot-candles
MENU
A list of selectable options displayed on the
Touch Panel Controller
.
METADATA
Descriptive data about the format of the content—i.e., “data about data”. When receiving metadata, digital cinema
projectors will know the correct aspect ratio of the image, and the sound processor will know the correct format of the
audio, all without effort on the part of the person setting up the show on a particular projector.
MIB
A database file defining a particular network object (such as a device: TPC, server, etc.) that can be monitored by a
network management system such as SNMP.
NTSC VIDEO
A video output format of some video tape and disk players. There are two types of NTSC (National Television
Standards Committee) video: NTSC 3.58 and NTSC 4.43. NTSC 3.58 is used primarily in North America and Japan.
NTSC 4.43 is less commonly used.
NON-CINEMA
Alternative program material such as concerts, plays, sporting events, and potentially corporate training or conferenc-
ing, presented in theatres in addition to motion picture exhibition. A non-cinema source connects to one of the
projector’s DVI ports.
NON-SYNC
Audio played in a theatre, generally from a CD, when the cinematic presentation is not running, such as during
intermissions and prior to the start of film presentation.
NON-UNICODE
The non-unicode method of encoding produces a concise character set of 256 alpha-numeric characters typically used
in for ASCII messaging in most Western languages. Virtually all TPC functions can be executed remotely via non-
unicode (default) or unicode messaging—this is auto-detected. Refer to
Unicode
.
OPTICAL SCREEN
A type of rear-projection screen which re-directs light through the screen to increase image brightness in front of the
screen. Screen gain is usually greater than 1 but audience viewing angles are reduced. Rarely used in cinema
applications.
