Numerical Values for Subjective Picture Quality in Television
C. A. Siocos · Journal of the SMPTE · 1971
The need for assigning numerical values to subjective picture quality is discussed. The applicability is investigated of the British Post Office impairment units to published American results on the subjective effects of differential gain, differential phase, relative chrominance delay and signal-to-noise ratio. The summability property of these impairment units is also checked, as far as the aforementioned USA results permit, and the results tend to indicate that it indeed holds.
