ATIS is the leading technical planning and standards development organization committed to the rapid development of global, market-driven standards for the information, entertainment and communications industry.
In the photosphere, i.e., visible disk of the Sun, a dark marking that manifests a magnetic anomaly that is associated with interference with radio communications on Earth. Note: Sunspot activity, i.e., the number of sunspots occurring at a given time or on a given day, is cyclic. The period of a cycle, from maximum through minimum and back to maximum sunspot count, is approximately 11 years.

In the presence of an electrical fault, the current that flows in the protective ground wire of a power distribution system.
Industry:Telecommunications
In the processing or transmission of digital data, an error-control procedure that is used to determine whether a block of data is structured according to given rules.
Industry:Telecommunications
In the propagation of an electromagnetic wave in a uniform waveguide, such as an optical fiber or metal waveguide, the parameter that indicates the phase change per unit distance of the wave at any point along the waveguide.
Industry:Telecommunications
In the public regulated telecommunications services, a service grade that is described in part 68, Title 47 of the Code of Federal Regulations. Note: Voice-grade service does not imply any specific signaling or supervisory scheme.
Industry:Telecommunications
In the public switched telephone networks, the equipment provided by a common carrier to accomplish electrical interconnection between customer-provided equipment and the facilities of the common carrier.
Industry:Telecommunications
In the quantization process, the discrete value assigned to a particular subrange of the analog signal being quantized.
Industry:Telecommunications
In the radio regime, a lens made of dielectric material that refracts radio waves in the same manner that an optical lens refracts light waves.

In the receipt and processing of digitized television transmissions, a method of covering up errors from dropouts by using the redundancy in most adjacent-frame image information. Note: Video images are frequently nearly identical from frame to frame. Adjacent video lines frequently have almost the same detail. It becomes possible, therefore, when a "burst error" involving the modification or loss of many recorded bits occurs, to determine (from adjacent image segments) a most probable substitution. Such substitutions, when infrequent and supported by the image redundancy, are often accepted by the viewers as "correct. " (This is a degree of freedom in image data recovery that is obviously not utilized when recording scientific and financial data. ) The additional information needed by the algorithm for decision and substitution is usually provided by a data-storage cache established during reproduction.
