GLOSSARY
DVI
Digital Visual Interface is a display interface developed in response to the proliferation of digital flat panel displays.
The digital video connectivity standard that was developed by DDWG (Digital Display Work Group). This connection standard offers
two different connectors: one with 24 pins that handles digital video signals only, and one with 29 pins that handles both digital
and analog video. This standard uses TMDS (Transition Minimized Differential Signal) from Silicon Image and DDC (Display Data
Channel) from VESA (Video Electronics Standards Association).
DVI can be single or dual link.
RS232
An Electronic Industries Association (EIA) serial digital interface standard specifying the characteristics of the communication path
between two devices using either D-SUB 9 pins or D-SUB 25 pins connectors. This standard is used for relatively short-range
communications and does not specify balanced control lines. RS-232 is a serial control standard with a set number of conductors,
data rate, word length and type of connector to be used. The standard specifies component connection standards with regard to
computer interface. It is also called RS-232-C, which is the third version of the RS-232 standard, and is functionally identical to the
CCITT V.24 standard. Logical '0' is > + 3V, Logical '1' is < - 3V. The range between -3V and +3V is the transition zone.
Scheimpflug principle
The "plane of sharp focus" can be changed so that any plane can be brought into sharp focus. When the DMD plane and lens plane
are parallel, the plane of sharp focus will also be parallel to these two planes. If, however, the lens plane is tilted with respect to the
DMD plane, the plane of sharp focus will also be tilted according to geometrical and optical properties. The DMD plane, the principal
lens plane and the sharp focus plane will intersect in a line below the projector for downward lens tilt.
SMPTE
Society of Motion Picture and Television Engineers - A global organization, based in the United States, that sets standards for
baseband visual communications. This includes film as well video standards.
