In constructive modulation systems, as within the earlier white facsimile transmission normal, the maximum luminance value is represented by the utmost service power; in unfavorable modulation , the utmost luminance value is represented by zero carrier energy. All newer analog video techniques use detrimental modulation apart from the French System L.
