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
