A single continuous line with continuity of tangent vector and of curvature. It is defined by its type, degree, and rational feature.
Industry:Entertainment
A video generator that produces a solid-color output which can be adjusted for hue, chroma, and luminance using the controls in the MATTE/BKGD control group.
Industry:Entertainment
In an (M) NTSC or (B, D, G, H, I) PAL video signal, the luma (black and white) and the chroma (color) information are combined together. To decode the video signal, the luma and chroma must be separated.
The chroma trap is a method of doing this.
Industry:Entertainment
A transition between signals selected on the Preset Background and Program Background buses, or between an “A” bus and “B” bus on an M/E.
Industry:Entertainment
a) The data that represents one of the two colordifference signals Cr and Cb.
b) Chrominance refers to the color information in a television picture. Chrominance can be further broken down into two properties of color: hue and saturation. See Chroma.
Industry:Entertainment
a) The immediate switching from one video source to another during the vertical blanking interval. The visual effect is an abrupt change from one picture to another.
b) The nearly instantaneous switch from one picture to another at the on-air output of the switcher. The switcher circuitry allows cuts only during the vertical interval of the video signal so as to prevent disruption of the picture. On the Vista, the Cut push-button in the Effects Transition control group activates an effects cut. The DSK Cut Key-In pushbutton cuts the downstream key on or off air. On AVCs, this is performed by a zero time auto transition.
Industry:Entertainment
a) Video that forms a background scene into which a key may be inserted. Background video comes from the Preset Background and/or Program Background bus or from an N/E “A” or “B” bus.
b) A solid-color video output generated by the color Background generator within the switcher for use as background video.
Industry:Entertainment
Describes the frequency response of the chrominance channel.
Industry:Entertainment
That frequency beyond which no appreciable energy is transmitted. It may refer to either an upper or lower limit of a frequency band.
