CIMM DEFINITION: As applied to Set-Top Box data measurement, noise is the ancillary, unmeasurable points of data that create large margins of error in measurement. It is said to result from having too small a sample size. “Noise” diminishes as the dataset moves from a sample to a full all-inclusive census.
2: The word “noise” is a carryover from audio practice. Refers to random spurts of electrical energy or interference. May produce a “salt-and-pepper” pattern over the picture. Heavy noise is sometimes called “snow.” (Source: CableLabs)
