A device used to correct problems related to the chroma of the video signal, as well as color balance and color noise.

This type of modeling is also a boundary representation method available in PictureMaker. The artist can define an object’s cross-section, and then extrude in the longitudinal direction after selecting an outline to define the cross-section changes in scale as it traverses the longitudinal axis.
Industry:Entertainment
A physical repositioning of the CCD, the camera element that translates light into electronic pulses for recording on videotape. The effect is to lengthen or shorten the distance between the lens and the CCD.
Industry:Entertainment
An NTSC artifact also sometimes referred to as moving dots; a crawling of the edges of saturated colors in an NTSC picture.
Chroma Crawl is a form of cross-luminance, a result of a television set decoding color information as high-detail luminance information (dots).
Most ATV schemes seek to eliminate or reduce chroma crawl, possibly because it is so immediately apparent.
Industry:Entertainment
Long distance digital data transport service such as Sonet, SDH, or Telecos.
Industry:Entertainment
The process of removing the color video information from a composite video signal where chrominance information is modulated on a color subcarrier. The phase reference of the subcarrier, is color burst which is a phase-coherent sample of the color subcarrier.
Industry:Entertainment
The signal-to-crosstalk noise ratio is the ratio, in decibels, of the nominal amplitude of the luminance signal (100 IRE units) to the peak-to-peak amplitude of the interfering waveform.

Refer to the NTSC Composite Receiver Model at the end of this glossary when studying this definition. After the (M) NTSC or (B, D, G, H, I) PAL video signal makes its way through the Y/C separator, by either the chroma bandpass, chroma trap, or comb filter method, the colors are then decoded by the chroma demodulator. Using the recovered color subcarrier, the chroma demodulators take the chroma output of the Y/C separator and recovers two color difference signals (typically I and Q or U and V).
