A) The process that establishes a fixed level for the picture signal at the beginning of each scanning line. b) The process whereby a video signal is referenced or “clamped” to a DC level to prevent pumping or bouncing under different picture levels. Without clamping, a dark picture would bounce if a white object appeared. Changes in APL would cause annoying pulsations in the video. Clamping is usually done at zero DC level on the breezeway of the back porch of horizontal sync. This is the most stable portion of a TV picture.

A) Refers to the composite video signal as it exists before modulating the picture carrier. Not modulated. Composite video distributed throughout a studio and used for recording is at baseband.
b) Video and audio signals are considered to be “prime,” or baseband. Video and audio can be broken down into more basic elements, but those elements no longer constitute the desired signal as a single element. Baseband video and audio signals are often AM or FM modulated onto a carrier frequency, so that more than one set of “prime” signals can be transmitted or recorded at the same time.

Rooms whose cleanliness is measured by the number of particles of a given size per cubic foot of room volume. For example, a class 100,000 clean room may have no more than 100,000 particles onehalf micron or larger per cubic foot. Similarly, for class 10,000 and class 100 rooms. In addition, a class 10,000 room may have no more than 65 five-micron particles per cubic foot, while class 100,000 may have no more than 700.¨

An information processing unit intended to remove the DC and low-order frequency distortion terms that result from use of record/reproduce transfer function which cannot pass DC in conjunction with a binary code that requires low-frequency response to DC (i.e., zero frequency) for accurate recovery of such a code.
Industry:Entertainment
A form of low-frequency distortion resulting in a shift in the DC level of the signal.
Industry:Entertainment
