Description
PC 3D Ready A projector that is PC 3D Ready can accept a 120Hz frame-
sequential 3D signal from a computer via either NVIDIA's 3D
Vision system or one of several educational software suites. These
projectors are not compatible with the HDMI
used on 3D Blu-ray players and set-top boxes. This type of projector
is also refered to as 3D Ready.
Persistence
The disposition of humans to amalgamate sequential still images into
of Vision
perceived motion. For most people, this occurs at around 16 fps.
Phase
The characteristic of when a wave is at its peak, trough, or zero point
going up or down. Measured in degrees. Two sine waves of the same
frequency that are 180 degrees out of phase will cancel each other
out, yielding no signal.
Pico Projector A marketing term to describe a small hand held projector that can
fit in your pocket. A pico projector can be a stand-alone device that
connects to a computer or other video device or a projection module
that is integrated with a phone, portable computer, MP3 player or
other small device.
Picture-in-
The ability of a projector (or any video display device) to display two
picture
independent video signals at once. One signal usually fills the main
screen and the other is displayed in an inset window. Usually the
audio from the image on the main screen is the default, and no audio
is available on the inset picture.
Poly-Si
One of several projector display technologies. Monochrome Poly-
(silicon) LCD
Si LCDs are typically placed in each of the three colour (red, green,
blue) light paths inside a projector to produce a colour image from
a common light source. Poly-Si technology is a bit faster than the
Active Matrix TFT providing slightly smoother video.
Power Focus
A motor driven lens that adjusts focus using a button on the
projector's control panel and/or a remote control.
Power Output With audio amplifiers, the amount of power sent to drive the
speakers. Peak output is quite often specified, which is somewhat
misleading compared to the average amount of power an amplifier
can continously produce (RMS rating).
Power Zoom
A zoom lens that is driven by a motor and controlled from the
projector's control panel and/or remote control.
Pre-amp
A switching device used to select a line-level audio signal for
amplification. Sometimes offers signal processing as well.
Progressive
A display mode in which all the horizontal lines of an image are
Scan
displayed at one time in a single frame, unlike an interlaced scan
in which a frame consists of two separate fields with the first
field consisting of odd horizontal lines and the second field even
horizontal lines. Progressive scan is used by projectors, computer
monitors, HDTV systems, and some digital camcorders. Progressive
Scan requires a faster horizontal scan frequency than interlaced
images of the same resolution
