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 mount
A type of lens mount. The lens can be inserted into the lens mount and quickly locked in place by simply rotating the lens locking ring.
Black balance adjustment
To balance the black levels of the R, G, and B channels of a video camera so that black has no color.
Black set
A reference level for black balance adjustment.
CCD
Center marker
A cross which indicates the center of the image on the viewfinder screen.
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. Clip lists can be created with
the scene selection function of this unit, and with the supplied
Color bar signal
A test signal which can be displayed as vertical bars of different colors on a color video monitor. This signal is used to check chrominance functions of color television and video systems such as cameras and monitors.
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 temperature in Kelvins (K) to represent the color of a light source, determined by heating a perfectly black body until its color matches that of the light source. Color temperature is higher when the color is bluish and lower when reddish.
Composite video signal
A video signal in which luminance and chrominance are combined along with timing reference “sync” information to make composite video.
CRT
DCC
Dynamic Contrast Control. A DCC circuit automatically adjusts the knee point according to the amount of incident light. A video camera containing a DCC circuit can handle a wide dynamic range of luminance.
Drop frame mode
SMPTE time code 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 time code to eliminate the discrepancy between
time code value and actual time by dropping two frames from the time code value at the beginning of each minute except every tenth minute.
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.
Flare
Dark or colored flashes caused by signal overload through extreme light reflections of polished objects or very bright lights.
Flange focal length
The distance from the plane of lens mounting flange to the image focal plane. Abbreviated to Ff.
Flicker
Repeated change of brightness on the screen, caused by light sources such as fluorescent light flashing at the frequency of alternating current.
Genlock
Generator lock. To synchronize the pulse generator built into video equipment to an external reference (master) sync signal.
