The simplest shading type is constant. The color of a constant shaded polygon’s interior pixels is always the same, regardless of the polygon’s orientation with respect to the viewer and light sources.
Constant shading is useful for creating light sources, for example. With all other shading types, a polygon changes its shade as it moves.

One who controls the compression process to produce results better than would be normally expected from an automated system.

Shot-to-shot picture fidelity. Improperly matched cameras may exhibit differences in level, balance, colorimetry, or defects that will cause the picture quality to change from shot to shot. These differences may present problems during editing, as the editor attempts to minimize differences.

Way of representing the I and Q components of QAM or QPSK modulation. The position of the points in the constellation diagram provides information about distortions in the QAM or QPSK modulator as well as about distortions after the transmission of digitally coded signals.

a) Any row of video crosspoints that allow selection of various sources to be selected, and the associated row of buttons for such selection.
Buses are usually associated with a given M/E or the DSK although they may be independent as in aux buses. Also, any row of video or key source selections which may or may not be selected by push buttons on a bus row. For example, key video selections on Ampex switchers appear on buses which are accessed and selected by keypads. Due to the fact that there is no associated row of buttons, this arrangement is called a “phantom bus.” b) A parallel data path in a computer.
Industry:Entertainment
An analog device that reduces the dynamic range of a signal by either reducing the level of loud signals or increasing the level of soft signals when the combined level of all the frequencies contained in the input is above or below a certain threshold level.

Most video cameras use an external DC voltage supply which is derived either from a battery belt worn by the camera operator, from a battery within the video recorder itself, or from the mains power supply (after voltage conversion).
