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.
The synchronization of audio and corresponding video signals so that there is no noticeable lack of simultaneity between them. Note: An example of a lip synchronization problem is the case in which television video and audio signals are transported via different facilities (e.g., a geosynchronous satellite link and a landline) that have significantly differently delay times, respectively. In such cases it is necessary to delay the audio electronically to allow for the difference in propagation times.
Industry:Telecommunications
The time a system or functional unit takes to react to a given input. Note: For example, in data processing, the response time perceived by the end user is the interval between (a) the instant at which an operator at a terminal enters a request for a response from a computer and (b) the instant at which the first character of the response is received at a terminal. In a data system, the system response time is the interval between the receipt of the end of transmission of an inquiry message and the beginning of the transmission of a response message to the station originating the inquiry.
Industry:Telecommunications
The unique network address that is assigned to a telephone user, i.e., subscriber, for routing telephone calls.
Industry:Telecommunications
The systematic performance of operations upon data such as handling, merging, sorting, and computing. Note: The semantic content of the original data should not be changed. The semantic content of the processed data may be changed. Synonym information processing.
Industry:Telecommunications
Use of a crypto-algorithm program by a computer to authenticate or encrypt/decrypt information.
Industry:Telecommunications
The time interval between (a) the instant that an enabling signal (as in a vogad or echo suppressor) is discontinued, and (b) the instant at which suppression ceases. 2. The time interval between (a) the instant a relay coil is de-energized, and (b) the instant that contact closure ceases (or, depending on the nature of the relay, is established. )
Industry:Telecommunications
The user that initiates a particular information transfer transaction. Note: The originating user may be either the source user or the destination user.
Industry:Telecommunications
Transmission in which (a) the frequencies produced by amplitude modulation are symmetrically spaced above and below the carrier and (b) the carrier level is reduced for transmission at a fixed level below that which is provided to the modulator. Note: In DSB-RC transmission, the carrier is usually transmitted at a level suitable for use as a reference by the receiver, except for the case in which it is reduced to the minimum practical level, i.e., the carrier is suppressed.
Industry:Telecommunications
The unauthorized use, copying, or distribution of software products.
