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 as video standards.
Trusted Device List (TDL)
The Goal of the TDL is to maintain timely and accurate information on participating auditoriums so that
participating subscribers can obtain information needed to issue KDMs. The TDL has several data sources:
Device manufacturers, Exhibitors, Deployment Entities, Integrators, Service Providers (interacting with
Exhibitors), regional authorities and Support.
USB
Universal Serial Bus (USB) is an industry standard developed in the mid-1990s that defines the cables,
connectors and communications protocols used in a bus for connection, communication, and power supply
between computers and electronic devices. USB 2.0 (also called "Hi-Speed"), adding higher maximum
signaling rate of 480 Mbit/s (effective throughput up to 35 MB/s or 280 Mbit/s), in addition to the "USB 1.x Full
Speed" signaling rate of 12 Mbit/s.[16] USB 2.0 connectors are usually colored black. USB 3.0 defines a new
SuperSpeed mode with a signaling speed of 5 Gbit/s and a usable data rate of up to 4 Gbit/s (500 MB/s). A
USB 3.0 port is usually colored blue, and is backwards compatible with USB 2.0.
