Abstract
The earliest method of broadcasting color television programs from magnetic tape attempted to preserve the time-base stability of the chrominance information with respect to a stable color subcarrier by treating the off-tape chroma information separately from the luminance. This method has commonly been known as nonphased color because it characteristically fails to preserve the relationship between subcarrier and sync. The relevant FCC specifications and a typical non-phased color system are described; an analysis of the output components shows the subcarrier to undergo full correction while the quadrature modulation is left uncorrected. A number of subjectively disturbing effects are identified, including loss of dot cancellation, loss of luminance resolution and impairment of hue quality.
