Final report of a feasibility study into the use of impairment units and their summation in the evaluation of video distribution systems / by: K.E. Hancock, J.N. Barry, C.L. Balko. : Co24-3/1-82-0039E-PDF
"Any video distribution system is subject to impairments of the information being distributed. In practice the technical quality of such a distribution system is determined by first specifying acceptable levels for each impairment of interest, and then measuring the impairments of the actual system against such specifications. Weaknesses of this traditional approach include the fact that the technical measurements have no provision to ensure specific correlation with the transmission of a satisfactory video display to the viewer, and the fact that there is little or no correlation between the individual parameters specified. Viewers of course see an image in which all impairments are present to a greater or lesser extent, and the acceptability of the image is determined by the combined effect of all impairments"--Summary, page ii.
