Glossary of terms
independently. See also I-frame (Intra-frame) and
P-frame (Predicted frame).
BIOS
Basic Input/Output System settings for
system components, peripherals, etc. This
information is stored in a special battery-powered
memory and is usually accessible for changes at
computer start-up.
bitmap
A graphics image in which a set of
values defines each pixel’s relative brightness and
color.
blackburst
A composite video signal that
combines the sync information of a basic video
signal with a pure black signal. Used as a reference
in synchronizing the different video sources in a
system. Also called color black.
burnt-in time code
Time code that’s
superimposed onto each frame of video, generally
created using the overlay feature of a VTR. Used
for rough-cut and edit-list processing. Also called
burn in.
bus
1. Electrical signal path between different
physical connection points. 2. System bus on
computers, represented by the expansion slot
connectors. 3. Movie-2 bus.
C
capture
The process of digitizing video or
audio material, usually from a VTR, and storing it
in a file on a hard disk.
card
DigiSuite card as assembled and installed.
For our purposes, a card is the final assembled
product, whereas a board is simply one the of the
printed circuit boards that make up a card.
card set
One or more DigiSuite cards
recognized by DigiSuite software as a single
functional unit. If a card set contains two or more
cards, these are connected by a Movie-2 bus.
There may be more than one card set connected by
a Movie-2 bus connector.
character generator
A device or computer
program used to create text that can be overlaid
onto video.
chroma key
An effect that makes portions of a
foreground image fully or partially transparent
based on the color of that image (or another
source), so that an underlying image can show
through. See also key source, self-key, and filled
key.
chrominance
The color portion of a video
signal that carries the hue and saturation
information. See also luminance.
codec
Compressor/decompressor. A processor
that compresses video to reduce its file size by
eliminating redundancies in information. It also
decompresses files to play them back.
color bars
A standard test signal that appears
as a series of vertical rows of color by which the
chrominance and video levels of a camera’s output
or a recorded signal can be checked.
compile
See render.
component video
A video signal having
separate channels for the video information, as
opposed to a combined (composite) signal. On
DigiSuite, analog component video refers to a
signal containing three channels: Y (luminance),
R-Y (red minus luminance), and B-Y (blue minus
luminance).
composite video
A video signal containing
luminance and chrominance information that has
been combined using a video standard such as
NTSC or PAL. See also component video.
CON 1 and CON 2
1. Male connectors (usually
with 90 or 70 pins) mounted at the top of a
DigiSuite card closest to the center of the card. 2.
Their female counterpart on a Movie-2 bus.
connector set
Combination of the Movie-2
bus connectors CON 1 and 2 on a DigiSuite card
and/or a Movie-2 bus.
