SWITCHER
A signal selector—specifically, the Marquee Signal Switcher formerly manufactured by Christie—can be connected
for adding more sources to a projector.
SYNC
This term refers to the part of the video signal that is used to stabilize the picture. Sync can occur in three forms:
• Composite sync: the horizontal and vertical components are together on one cable.
• Sync-on-green: the sync is part of the green video.
• Separate sync or H.SYNC and V.SYNC: the horizontal and vertical components of the sync are on two
separate cables.
SYNC WIDTH
The duration of each sync pulse generated by a computer. The sync width is part of the blanking time.
TTL VIDEO
A type of RGB video with digital characteristics.
TAMPER INTERLOCK
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.
TERMINATED
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).
THROW DISTANCE
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 ratio = throw distance / screen width.
TINT
Balance of red-to-green necessary for realistic representation of NTSC signals.
TMDS
Transition Minimized Differential Signaling is the basis for DVI (Digital Visual Interface)
TRAILER
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.
