value set -

A control used to present a series of mutually exclusive graphical choices. A tool palette in a paint program can be implemented using a value set.

Videocassette recorder.

Virtual device driver.

Virtual device helper.

Video display processor.

See coordinate graphics.

An extension to an MCD to execute hardware specific commands.

Very high speed. A consumer and industrial tape format (VHS format).

A vicon, or video icon, can be an animation or motion video segment in icon size. Usually this would be a short, repeating segment, such as an animation of a cassette tape with turning wheels.

Pertaining to the portion of recorded information that can be seen.

See aspect ratio.

Provides access to and operation of the standard video attributes: brightness, contrast, freeze, hue, saturation, and sharpness. All device communication and user interface support is handled by the control.

Refers to the standard video attributes: brightness, contrast, freeze, hue, saturation, and sharpness.

A section of filmed or videotaped material.

See clipping.

Any system for converting analog video material to digital representation. (For example, see DVI.)

The buffer containing the visual information to be displayed. This buffer is read by the video display controller.

The graphics or video adapter that connects to a display and presents visual information.

A device (adapter) that transforms the high-resolution digital image from the computer into a standard television signal, thereby allowing the computer to create graphics for use in video production.

A graphics controller for color displays. The pel resolution of the video graphics adapter is 4:4.

(1) A still video image that has been captured. (2) Synonymous with image and still image.

A display device capable of accepting a video signal that is not modulated for broadcast either on cable or over the air; in videotaping, a television screen located away from the set where the footage can be viewed as it is being recorded.

See overlay.

See overlay device.

In a dual plane video system, the video plane contains the video. This video plane will be combined with the graphics plane to create an entire display image.

A subsystem that performs output from video source to video window.

The compression quality level setting to be set for the CODEC. This value is in the range of 0 (min) - 100 (max).

Frame rate for recording as an integral number of frames per second. This sets the target capture rate, but there are no assurances this rate will be attained. Drop frame records will be inserted into the output data stream to indicate frames dropped during the capture/record process.

Frame rate for recording as the time duration of each frame in microseconds. Useful for setting non-integer frame rates, for example, 12.5 FPS of a PAL videodisc: 1000000/12.5 = 8000 microseconds.

An electrical signal containing video information. The signal must be in some standard format, such as NTSC or PAL.

Vendor Specific Driver

(1) Expanding or reducing video information in size or area. (2) See also aspect ratio.

A device that emits a video signal in one standard into another device of different resolution or scan rate.

A contiguous set of recorded data from a video track. A video segment might or might not be associated with an audio segment.

An electrical signal containing video information. The signal must be in some standard format, such as NTSC or PAL.

The ability of an application to change to an alternate video input using the connector command.

See tearing.

A means of telecommunication characterized by audio and video transmission, usually involving several parties. Desktop video teleconferencing could involve having the audio and video processed by the user's computer system, that is, with the other users' voices coming through the computer's speaker, and video windows of the other users displayed on the computer's screen.

A device for recording or playing back videocassettes.

A disc on which programs have been recorded for playback on a computer (or a television set); a recording on a videodisc. The most common format in the United States and Japan is an NTSC signal recorded on the optical reflective format.

Provides access to and operation of the following videodisc functions: eject, pause, play forward, play reverse, position, record, repeat, rewind, scan forward, scan reverse, step forward, step reverse, and stop. All device communication and user interface support is handled by the control.

(1) The tape used to record visual images and sound. (2) To make a videotape of. (3) A recording of visual images and sound made on magnetic tape. (All shooting is done in this format, even if the results are later transferred to videodisc or film.)

A device for recording and playing back videotapes. (The professional counterpart of a consumer VCR.)

A system that provides two-way interactive information services, including the exchange of alphanumeric and graphic information, over common carrier facilities to a mass consumer market using modified TV displays with special decoders and modems.

Graphical PM-style windows in which video is displayed. Most often associated with the video overlay device.

The form in which an object is presented. The four kinds of views are: composed, contents, settings, and help.

An area on the usable area of the display surface over which the developer has control of the size, location, and scaling, and in which the user can view all or a portion of the data outlined by the window.

A system service that is available to perform essential functions.

Script abbreviation for voice-over.

(1) The voice of an unseen narrator in a video presentation. (2) A voice indicating the thoughts of a visible character without the character's lips moving.

The intensity of sound. A volume of 0 is minimum volume. A volume of 100 is maximum volume.

Video programming interface.

Videotape recorder.
