Abstract
The authors present a method by which an estimate of the signal-to-noise ratio of a television broadcast picture can be made using excursions from the mean signal level in both the horizontal and vertical directions. The method depends on a determination of the two-dimensional spectral components of the noise and can yield nonintrusive measurements during normal broadcasts. In addition, the method can be used on pictures with no areas of constant luminance. The results obtained are consistent with those produced by an industry standard instrument
