Y'IQ, YIQ
For Y'IQ, YIQ we have a term and definition in Multimedia.
Y'IQ, YIQ (Multimedia) 
Y'IQ is a color space optionally used by the NTSC video system. The Y' component is the black-and-white portion of the image. The I and Q parts are the color difference components; these are effectively nothing more than color placed over the black and white, or luma, component. Many people use the YIQ notation rather than Y'IQ or Y'I'Q'. The technically correct notation is Y'I'Q' since all three components are derived from R'G'B'.
