A measure of voltage, current, or power gain. One bel is defined as a tenfold increase in power. If an amplifier increases a signal’s power by 10 times, its power gain is 1 bel or 10 decibels (dB). If power is increased by 100 times, the power gain is 2 bels or 20 decibels. 3 dB is considered a doubling.

A) An electronic limit usually imposed in cameras to avoid overly bright or dark signals. When improperly applied, can result in loss of picture information in very bright or very dark areas. Also used in switchers to set the cutoff point for mixing video signals. b) The electronic process of shearing off the peaks of either the white or black excursions of a video signal for limiting purposes. Sometimes, clipping is performed prior to modulation, and sometimes to limit the signal so it will not exceed a predetermined level.

Originally Bell Telephone Laboratories, the research arm of the Bell System. When AT&T divested itself of its regional telephone companies, Bell Labs was split. One division, still called Bell Labs, belongs to AT&T and is a proponent of a particular ATV system (SLSC). The other division, called Bellcore for short, belongs to the Bell regional holding companies (RHCs) and is, among many other R&D projects, investigating mechanisms for reducing the bit rate of digital video transmission, which may be applicable to ATV. Bellcore has formed a joint venture with NHK for HDTV research.

Circuitry used to prevent illegal colour conversion. Some colours can be legal in one colour space but not in another. To ensure a converted colour is legal in one colour format after being converted (transcoded) from another, the clipping logic clips the information until a legal colour is represented.
