AES/EBU
A standard established jointly by the
AES (Audio Engineering Society)
and EBU (European Broadcasting
Union) for serial transmission of
digital audio. Two channels of audio
can be transmitted via a single
connector.
Aliasing
Distortion which occurs during
sampling to convert analog signals to
digital.
ATW
Auto Tracing White balance. The
white balance is automatically
adjusted for the lighting conditions
during shooting.
Bayonet type
A type of lens mount. The lens can be
inserted into the lens mount and fixed
in place by rotating a ring.
Black balance
To balance the black level of the R,
G, and B signals so that black has no
color.
Black set
A reference level for black balance
adjustment.
CCD
Abbreviation for charge-coupled
device. A semiconductor device used
in place of a camera pickup tube. A
semiconductor used in place of a
camera tube. The CCD converts light
into electrical charge, and outputs the
electrical charge in the form of
varying voltages.
Center marker
A cross on the viewfinder screen that
indicates the center of an image.
Clip
A recording unit. Clips are created
every time recording starts and stops.
Clip list
A list of locations in the material
recorded on the disc, arranged in any
order. Clips lists can be created with
the scene selection function of this
unit, and with the supplied PDZ-1
Proxy Browsing Software.
Color bar signals
Test signals displayed on the screen
as multicolored vertical stripes. Used
for adjustment of hue, and saturation
of a video camera and video monitor.
Color subcarrier
In a composite video signal, a signal
superimposed upon the picture
(luminance) information for the
purpose of conveying the associated
color information. Color and
saturation information is conveyed
by the phase and amplitude of the
color subcarrier. Also called
subcarrier.
Color temperature
The color quality of light, expressed
in Kelvin (K).
Reddish colors have a lower color
temperature, and blueish colors a
higher color temperature.
CRT
Cathode-Ray Tube. Video camera
viewfinders are equipped with a CRT
image display, so you can monitor
what you are shooting.
DCC
Abbreviation for dynamic contrast
control. To provide a larger dynamic
range for a video camera (the range
of brightnesses of subjects that can be
handled by the imaging device), the
knee-point is automatically adjusted
with variations in the incident light.
Drop-frame mode
SMPTE timecode runs at 30 frames/
second, while the NTSC color
television system runs at about 29.97
frames/second. Drop-frame mode
adjusts the running of timecode to
eliminate the discrepancy between
timecode value and actual time by
dropping two frames from the
timecode value at the beginning of
each minute except every tenth
minute.
EBU
Abbreviation for European
Broadcasting Union. A professional
broadcasting establishment in
Europe.
E-E mode
Electric-to-Electric mode. When you
operate a VDR in E-E mode, input
video and/or audio signals pass
through electric circuits only and
then come out from the output
connectors, without passing through
electromagnetic conversion circuits
such as recording heads.
EFP
Electronic Field Production. The use
of electronic equipment such as
portable video cameras, VTRs, and
sound equipment for television
production outside studios.
ENG
Electronic News Gathering. The use
of electronic equipment such as
portable video cameras, VTRs, and
sound equipment for the production
of daily news stories and short
documentaries.
Essence mark
A type of metadata that may be set for
a specified frame.
EXT TC (External timecode)
A timecode input from external
equipment together with audio data.
It corresponds to the conventional
timecode recorded on tape based
media. Instead the EXT TC is usually
used to record timecodes and audio
signals that are played back by
equipment that is not synchronized
with the reference video signal.
Ff
See “Flange focal length”.
Flange focal length
The distance from the plane of lens
mounting flange to the image focal
plane. Abbreviated to Ff.
Flare
Dark or colored flashes caused by
signal overload through extreme light
reflections of polished objects or very
bright lights.
Flicker
Repeated changes in screen
brightness caused by an interference
