Appendix B, DigiSuite Glossary
posterization
An effect that reduces the
various luminance levels of an image so that it
looks flat or two-dimensional, somewhat like a
poster or paint-by-number picture.
proc amp An electronic device that adjusts the
different aspects of a video signal, such as its hue,
saturation, and contrast.
R
realtime effect An effect that is played back
instantly, without having to be rendered by an
editing program.
Compare with software effect.
render
To compute an image or effect using a
nonlinear editing, compositing, or animation
program. The result is generally saved in a file on
the computer.
Also called compile.
RGB video A component video signal that uses
three signals to carry the separate Red, Green, and
Blue channels of colored images.
roll 1. Vertical movement of text across the
screen. Also called scroll. See also crawl.
2. Unwanted vertical roll of a video image,
indicating unstable sync.
RS-232
A non-differential serial data
transmission standard used for computer
connections.
RS-422 A differential serial data transmission
standard that is often used for linking video
production equipment (VTRs, mixers, etc.).
Because this standard is differential, RS-422
connections are less subject to interference and
noise than RS-232 connections.
S
saturation A measure of the depth of a color.
Fully saturated colors are vivid, while colors that
lack saturation look washed out or faded.
scroll See roll (1).
SDI Serial Digital Interface. A communications
standard for broadcast digital equipment in which
data is transmitted and received one bit at a time
over a signal line.
self-key A key effect in which the key source
image is also the foreground image. Contrast with
filled key.
serial control A method of remotely
controlling a device via a data line. The control
data is transmitted in serial form (that is, one bit
after another).
soft key A key effect that has a fuzzy, soft edge
or semi-transparent areas. See also hard key.
software effect An effect that must be
rendered by an editing program before it can be
played back.
Compare with realtime effect.
soft wipe A split screen or wipe effect with a
soft border or edge where the two images join.
spatial redundancy reduction See intra-
frame compression.
striping a tape Preparing a tape for editing by
recording continuous control track, time code, and
a video signal (such as black or color bars).
SVCD
Super Video CD. A standard for storing
video and audio on a CD that provides better video
quality than VCD and standard VHS. Video is
compressed using MPEG-2 at 2500 Kbps, and
audio is compressed as MPEG-1, layer II, at
224 Kbps. An SVCD can hold about 30 minutes of
material. Super Video CDs will play back on some
DVD set-top players.
See also VCD.
S-Video See Y/C video.
sync A circuit or signal that directs the electron
gun in a camera or TV picture tube to hold a
picture steady on the screen. It also synchronizes
the electronics of other video equipment.
sync generator An electrical device that
generates sync (timing) signals used to
synchronize video equipment and keep pictures
stable on the screen.
