The Internet standard protocol developed to manage nodes (servers, workstations,
routers, switches and hubs etc.) on an IP network. SNMP enables network
administrators to manage network performance, find and solve network problems,
and plan for network growth.
The device (such as a server) connected to the projector for supplying incoming data.
See Channel.
A signal selector—specifically, the Marquee Signal Switcher formerly manufactured
by Christie—can be connected for adding more sources to a projector.
The part of the video signal that stabilizes the picture. Sync can occur in three forms:
1)
"Composite sync": the horizontal and vertical components are together on one
cable.
2)
"Sync-on-green": the sync is part of the green video.
3)
"Separate sync" or "H.SYNC and V.SYNC": the horizontal and vertical
components of the sync are on two separate cables.
The duration of each sync pulse generated by a computer. The sync width is part of
the blanking time.
A type of RGB video with digital characteristics.
A switch that detects when the light engine compartment is unlocked. It is monitored
by the electronics to log accesses. If activated, encrypted playback such as cinema
presentations for example will be interrupted.
A wire connecting a single video source to a display device, such as a projector, must
be terminated by a resistance (usually 75 for video).
The distance between the front feet of the projector and the screen. Also called
"Projector-to-Screen Distance". Always use the correct Christie throw distance
formula to calculate the proper throw distance (±5%) required for your lens.
Throw ratio = throw distance / screen width.
Balance of red-to-green necessary for realistic representation of NTSC signals.
Transition Minimized Differential Signaling is the basis for DVI (Digital Visual
Interface)
Motion picture material presented prior to screening of the feature, so called because
they were originally presented following the feature. Trailers are generally
manufactured and created by the distributor in close cooperation with the producer;
they are distributed by trailer specialists at no charge. Types of trailers include
previews, teasers, house and/or policy trailers, advertisements, and public service
announcements.
The Unicode method of encoding produces a very large character set typically
required for ASCII messaging in non-Western languages such as Chinese, Russian,
etc. In unicode, every number (code) is unique to a single character. A limited
number of TPC functions can be executed remotely via unicode or non-unicode
(default) messaging—this is auto-detected. See also non-unicode.
