Glossary of terms
AVI
Audio Video Interleaved. A video file
format designed for the Microsoft Windows
environment.
See also
codec.
A/V drive
A hard drive capable of storing high-
bandwidth audio/video data.
B
backplane
PCB (printed circuit board) on a
Movie-2 bus connector.
base board Printed circuit board (and mounted
components such as integrated circuits, etc.) that is
inserted into the computer’s expansion slot. A
module board is often attached to the base board.
B-frame (Bi-directional frame) A frame
created during the MPEG or MPEG-2 IBP
compression process. A B-frame is generated by
forwards and backwards referencing of the P-
frames and I-frames respectively, which allows it
to have the highest compression ratio of the three
frame types. B-frames contain only predictive data
(that is, not enough data to make up an entire
picture), and therefore cannot be edited
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.
Blue Book standard See DV.
blur effect A Matrox effect that uses various
levels of intensity to blur an image.
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 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.
