1、 AMERICAN NATIONAL STANDARD FOR TELECOMMUNICATIONS ATIS-0100502.2005(R2015) System M-NTSC Television Signals Network Interface Specifications and Performance Parameters As a leading technology and solutions development organization, ATIS brings together the top global ICT companies to advance the in
2、dustrys most-pressing business priorities. Through ATIS committees and forums, nearly 200 companies address cloud services, device solutions, emergency services, M2M communications, cyber security, ehealth, network evolution, quality of service, billing support, operations, and more. These prioritie
3、s follow a fast-track development lifecycle from design and innovation through solutions that include standards, specifications, requirements, business use cases, software toolkits, and interoperability testing. ATIS is accredited by the American National Standards Institute (ANSI). ATIS is the Nort

5、ion (CITEL). For more information, visit . AMERICAN NATIONAL STANDARD Approval of an American National Standard requires review by ANSI that the requirements for due process, consensus, and other criteria for approval have been met by the standards developer. Consensus is established when, in the ju
6、dgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a
7、concerted effort be made towards their resolution. The use of American National Standards is completely voluntary; their existence does not in any respect preclude anyone, whether he has approved the standards or not, from manufacturing, marketing, purchasing, or using products, processes, or proced
8、ures not conforming to the standards. The American National Standards Institute does not develop standards and will in no circumstances give an interpretation of any American National Standard. Moreover, no person shall have the right or authority to issue an interpretation of an American National S
9、tandard in the name of the American National Standards Institute. Requests for interpretations should be addressed to the secretariat or sponsor whose name appears on the title page of this standard. CAUTION NOTICE: This American National Standard may be revised or withdrawn at any time. The procedu
10、res of the American National Standards Institute require that action be taken periodically to reaffirm, revise, or withdraw this standard.

This standard defines neither the interconnection nor the performance characteristics of specific apparatus or equipment. 1.2 Purpose The purpose of this standard is to assure the uniform application
12、of standard values of transmission parameters for television signals transported by portions of the telecommunications network. It is intended to provide a common understanding by both suppliers and their customers. 1.3 Application The primary applications of this standard are for specifying and eva
13、luating the performance of a transmission service provided by common carriers. These services are used to transport the audio and video portions of broadcast-quality television signals.

14、this text, constitute provisions of this American National Standard. At the time of publication, the edition indicated was valid. All standards are subject to revision, and parties to agreements based on this American National Standard are encouraged to investigate the possibility of applying the mo
15、st recent edition of the standard indicated below. ANSI/IEEE 743-1995, IEEE Standard equipment requirements and measurement techniques for analog transmission parameters for telecommunications.13 DEFINITIONS 3.1 Special word/phrase usage 3.1.1 exchange carrier (EC): The telecommunications common car
16、rier franchised to provide telecommunications services within one or more exchanges. An EC may also provide exchange access service, intra-LATA long-distance service, and - in some unusual cases - inter-LATA service. 3.1.2 hypothetical reference transport service channel: A hypothetical reference tr
17、ansport service channel is a model used to define administration and jurisdictional responsibilities. These models, discussed in clause 6, apportion transmission parameter values by facility lengths. Facility lengths specified as short haul, medium haul, satellite, long haul, and end-to-end are defi
18、ned in 6.4. 3.1.3 interexchange carrier (IC): A telecommunications common carrier authorized to provide telecommunications services between LATAs. An IC may also provide service within some LATAs. 3.1.4 local access and transport area (LATA): A geographic area established for the provision and admin
19、istration of telecommunications services. A LATA encompasses one or more exchanges that have been grouped to serve common social, economic, and other purposes. 3.1.5 network interface (NI): The point of demarcation between the carriers facilities and the customers installation that establishes the t
20、echnical interface and division of operational responsibility. 3.1.6 point of termination (POT): The point of demarcation between carriers that establishes the technical interface and division of operational responsibility. 3.1.7 transmission service channel: A one-way transmission path between two
21、designated points (see 6.3). 3.1.7.1 end-to-end: A transmission service channel employing various circuits, such as a terrestrial or satellite inter-LATA transmission service channel, in conjunction with its associated access transmission service channels. 3.1.7.2 long haul: A transmission service c
