GUI (Graphical User
Interface)
A user interface which, unlike
traditional text-based interfaces,
is designed around graphical
elements such as buttons and
menus.
Intercom
A network that allows staff
members to talk to each other
during program production.
Host name
A name assigned to a computer
on a network to make it easier to
identify. Usually consisting of
alphanumeric characters,
although conventions differ
according to the system. The
most commonly used types are
the terminal identifiers to the
left of Internet domain names.
i.LINK
The high-speed serial bus
standard IEEE 1394.
Also called FireWire. Allows
connections between computers
and peripherals, and also direct
connections between digital
devices such as digital cameras.
IPv6
The next-generation Internet
Protocol, the successor to the
current IPv4 protocol.
IRE (International Radio
Engineers)
A measure of the brightness
level of video on the grayscale,
ranging from 0 to 100. The
brightness level of black is
sometimes set at 0 IRE and
sometimes set at 7.5 IRE.
Limiter
A function which prevents
audio levels from exceeding a
specified threshold. Used to
suppress peaks in audio with
large differences in amplitude.
Logo
A permanently visible mark
shown in video for the purpose
of copyright protection.
Luminance key
A method of composing a
picture by deleting video which
contains components of a
specified luminance
(brightness). Typically used to
extract bright characters from a
dark background, so that only
the characters can be added to
the composed picture.
Mix
A type of transition effect. A
new picture is mixed into an old
picture, eventually replacing the
old picture.
Monitor
To listen to audio and view
video. Or a device for viewing
and listening.
Motion JPEG2000
An extension to the JPEG2000
image compression format that
enables video recording. It
provides picture quality
comparable to the DV format,
with file sizes that are smaller
than DV. It is noted for high
compression ratios in scenes
with rapid movement, which are
problematic for the MPEG
format.
Oscillator
A transmitter that oscillates at a
fixed frequency, such as a sine
wave. This unit is equipped with
an internal audio oscillator.
Pan
In audio, to adjust the right/left
balance.
In video, to move the camera to
the left and right.
PFL (Pre-Fader Listen)
Monitoring audio before level
adjustments with the audio
channel faders. Used to check
the input audio. On this system,
pan and level control are not
applied to PFL audio, even if
trim, filter, EQ, pan, and level
control settings have been
made.
Picture-in-Picture (PinP)
An effect achieved by
embedding a video within
another video.
Post-Fader
Audio signals after the
application of all adjustments
except pan.
Pre-Fader
Audio signals before the
application of any adjustments
with audio channel faders. All
other adjustments are the same
as those for Post-fader. Pre-
fader audio can be output from
the AUX output connector.
Preset
A function which allows a set of
electrical settings to be saved
and reproduced as a single set of
data. This system has a camera
preset function.
Program (PGM) signal
output
The final video and audio
signals output from this system,
after the application of effects.
The video seen by viewers.
RCA pin
A connector used on consumer
audio equipment. Connectors
come in color-coded pairs
(often white for left and red for
right). Also used for video
signals (color yellow).
