raster graphics -

Computer graphics in which a display image is composed of an array of pels arranged in rows and columns.

Synonym for original footage.

A technique used by 3-D rendering software programs that automatically figures an object's position in three dimensions and calculates shadows, reflections, and hidden surfaces based on user-entered light locations and material characteristics. (In other words, if the user orders an object to be a mirror, the computer produces the mirror with all its correct reflective properties.)

(1) Pertaining to the processing of data by a computer in connection with another process outside the computer according to time requirements imposed by the outside process. This term is also used to describe systems operating in conversational mode and processes that can be influenced by human intervention while they are in progress. (2) A process control system or a computer-assisted instruction program, in which response to input is fast enough to affect subsequent output.

Refers to the capturing of video and audio data in real time, as the analog signals are generated from the video source device. The video source device can be a camcorder, or a videotape or videodisc player.

To transfer data from one source (for example, microphone, CD, videodisc) or set of sources to another medium.

The storage format of standard audio CDs. See also compact disc, digital audio (CD-DA).

(1) Refers to the complete frame that is created at periodic intervals in the output stream. An editing operation always begins at a reference frame. (2) Synonymous with key frame and I-frame. (3) See delta frame.

See optical reflective disc.

In videotaping, to create a realistic image from objects and light data in a scene.

A mode which causes the medium to go to the beginning and start replaying when it reaches the medium's end.

(1) In computer graphics, a measure of the sharpness of an image, expressed as the number of lines and columns on the display screen or the number of pels per unit of area. (2) The number of lines in an image that an imaging system (for example, a telescope, the human eye, a camera, and so on) can resolve. A higher resolution makes text and graphics appear clearer.

As used in the multimedia operating system, any specific unit of data created or used by a multimedia program. See also static resource and dynamic resource.

A system service that loads, saves, and manipulates multimedia program units of data.

A tagged file format framework intended to be the basis for defining new file formats.

Recovery processing performed by sync-point services when the failure of a session, transaction program, or LU occurs during sync-point processing. The purpose of resync is to return protected resources to consistent states.

A minimum time difference expressed in MMTIME format.

A data format for multimedia products.

To advance the medium in the backward direction quickly, and optionally allow the user to scan the medium.

Revisable Form Text : Document Content Architecture.

Color coding where the brightness of the additive primary colors of light, red, green, and blue, are specified as three distinct values of white light.

Resource interchange file format.

A chunk with a chunk ID of RIFF. In a RIFF file, this must be the first chunk.

A file containing multiple file elements or one file element that makes up the entire RIFF file. The MMIO manager provides services to find, query, and access any file elements in a RIFF compound file. Synonym for bundle file.

A camera setup that projects live-action film, one frame at a time, onto a surface so that an animator can trace complicated movements. When filmed, the completed animation matches the motion of the original action.

(1) The result of the offline edit. (2) A video program that includes the appropriate footage in the correct order but does not include special effects.

Real-time MIDI subsystem.
