The maximum number of alternate white and black horizontal lines that can be
distinguished on a screen when a photographic target is placed between the lens and a
light source and illuminated by that source.
The maximum number of pixels that the projector can display horizontally and
vertically across an image, such as 1024 x 768 (called XGA).
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 time required by the video amplifier of the projector to increase its output from
10% to 90% of the maximum value.
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.
The horizontal or vertical frequency at which images are generated.
One horizontal line on the display.
A video output format of some video tape and disk players (used primarily in
France). SECAM (Sequential Couleur á Mémoire) signals are similar in resolution
and frequency to PAL signals. The primary difference between the two standards is
in the way color information is encoded.
A slidebar is a graphical display of an adjustable setting. The numerical setting often
represents a percentage but can be a specific unit such as degrees Kelvin.
The device, such as a computer or VCR, connected to the projector for display. A
source may have numerous corresponding channels defined and recognized by the
projector. See Input.
See Channel.
A signal selector that can be connected to a projector for the purpose of adding more
sources.
This term refers to the part of the video signal that is used to stabilize the picture.
Sync can occur in three forms:
1) "Composite sync": the horizontal and vertical components are together on one
cable.
2) "Sync-on-green": the sync is part of the green video.
