The area (in pixels, for digital images) that constitutes the entire motion picture frame
image. Compare: active picture.
The distance between the projector's front feet centers and the screen. Also called
"Throw Distance”.
Shifting the frequency, sample rate, or frame rate to as to achieve a target frequency
or time relationship with another signal, most commonly by +/- .1%–the ratio of
NTSC to B&W TV frame rates. See: 3:2 pulldown.
A selectable TPC menu item that unfolds into a list of options pertaining to it.
A manufacturer of a digital video recorder/player/server, QuBit, frequently used for
providing digital cinema data. QuVis image compression uses a proprietary
technology called Quality Priority Encoding, based on wavelets, in which the user
selects a quality level based on signal-to-noise ratio. The data rate varies to
efficiently maintain that quality level. Frames are coded individually.
A translucent panel for screen projection. Incident light travels through the incident
surface of a rear screen and forms an image on the other surface. Rarely used for
cinema applications.
Composite positive motion picture prints, generally made from internegatives,
intended for distribution to exhibitors.
The ability to manipulate the physical size, placement and/or aspect ratio of an
image. Also called scaling.
The maximum number of pixels that the projector can display horizontally and
vertically across an image, such as 1280 x 1024 (called SXGA) or 2048 x 1080.
The minimum time required for a CRT projector to move the position of the scanning
spot from the right edge to the left edge.
The video output (analog or digital) of most computers. Analog RGB video can have
3, 4, or 5 wires — one each for red, green, and blue, and either none, one or two for
sync. For three-wire RGB, the green wire usually provides sync. (See TTL Video).
A common asynchronous data transmission standard recommended by the
Electronics Industries Association (EIA). Also called serial communication.
A less common asynchronous data transmission standard in which balanced
differential voltage is specified. RS-422 is especially suited to long distances.
The output from certain video tape players and video equipment. S-Video separates
sync and luminance from color information, typically producing a higher quality
display than composite video. Also known as Y/C.
The horizontal or vertical frequency at which images are generated. Also known as
scan rate or refresh rate.
One horizontal line on the display.
