Industry:Entertainment
The amount of colour detail available in a television system, separate from any brightness detail. In almost all television schemes, chroma resolution is lower than luminance resolution, matching visual acuity. Horizontal chroma resolution is only about 12 percent of luminance resolution in NTSC; in advanced schemes it is usually 50 percent.
See also Resolution.

A type of scalability (which is a subset of SNR scalability) where the enhancement layer(s) contain only coded refinement data for the DC coefficients and all the data for the AC coefficients of the chroma components.
Industry:Entertainment
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 programme 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 colour information in a television picture. Chrominance can be further broken down into two properties of color: hue and saturation. See Chroma.
