Abstract: Delay difference between the luminance and chrominance information of the NTSC color television signal causes colors to shift to the left or right of objects in the viewed color picture. This delay difference can occur during the processing or transmission of the color signal resulting in two basic delay difference types. Flat delay is the type of delay difference that can occur when the luminance and chrominance signals are separated, as frequently happens during signal processing, and is a function of the absolute delays of the separate luminance and chrominance signal paths. Shaped delay can occur during the transmission of the composite color signal and is a function of the delay characteristic of the transmission system. A series of subjective tests was designed to evaluate the effects of both flat and shaped delay on color TV pictures. Expert observers used a seven-point comment scale ranging from “not perceptible” to “extremely objectionable,” to rate picture impairments resulting from various magnitudes of delay difference.
