CIMM DEFINITION: Point in a cable television system that interconnects traditional coaxial cable and fiber-optics. The place where an optical signal is converted to a radio frequency (RF) signal, or vice versa. (Source: CableLabs)

2: In Set-Top Box measurement it is the level of sample or census size of less than a certain number of television homes for Set-Top Box data measurement or reporting purposes. Granularity from Zone level to Node to a household level to a set level.

3: In computing, a node is a unique processing location device that has a unique identifier such as MAC Address.

4: “In a digital cable context, a node is the switching station that converts the fiber optic signal from the head end into the electrical signal transmitted over coaxial cable on the proverbial “last mile” of a Hybrid-Fiber-Coax (HFC) distribution network. Ideally, such a node services approximately 500 homes, but in practice nodes may service up to 1000 to 1500 homes. The return path bandwidth is shared by all homes in a node.” (Source: FourthWall Media)

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)
