4、TE (the Society of Motion Picture and Television Engineers) is an internationally-recognized standards developing organization. Headquartered and incorporated in the United States of America, SMPTE has members in over 80 countries on six continents. SMPTEs Engineering Documents, including Standards,
5、 Recommended Practices, and Engineering Guidelines, are prepared by SMPTEs Technology Committees. Participation in these Committees is open to all with a bona fide interest in their work. SMPTE cooperates closely with other standards-developing organizations, including ISO, IEC and ITU. SMPTE Engine
6、ering Documents are drafted in accordance with the rules given in its Standards Operation Manual. SMPTE ST 2082-1 was prepared by Technology Committee 32NF. Intellectual Property At the time of publication no notice had been received by SMPTE claiming patent rights essential to the implementation of
7、 this Standard. However, attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. SMPTE shall not be held responsible for identifying any or all such patent rights. Introduction This section is entirely informative and does not form an int
8、egral part of this Engineering Document. SMPTE ST 2082-1 defines a bit-serial data interface for the transport of 12 Gb/s nominal component digital signals or packetized data. The mapping of various source image formats to the bit-serial data structure defined here in this document are described in
9、additional SMPTE ST 2082 document parts. SMPTE ST 2082-0 contains an informative roadmap for the 12 Gb/s Signal/Data Serial Interfaces. End users are cautioned that they should work with Serial Digital Interface equipment vendors to ensure the electrical and mechanical capabilities of cables and con
10、nectors whether existing or new in support of this interface meet their requirements. SMPTE ST 2082-1: 2015 Page 3 of 14 pages 1 Scope This standard describes the electrical and physical characteristics of a 12G-SDI coaxial cable interface suitable for applications where the signal loss does not exc
11、eed an amount specified by the receiver manufacturer. Typical loss amounts would be in the range of up to 40 dB at one-half the clock frequency. 2 Conformance Notation Normative text is text that describes elements of the design that are indispensable or contains the conformance language keywords: “
12、shall“, “should“, or “may“. Informative text is text that is potentially helpful to the user, but not indispensable, and can be removed, changed, or added editorially without affecting interoperability. Informative text does not contain any conformance keywords. All text in this document is, by defa
13、ult, normative, except: the Introduction, any section explicitly labeled as “Informative“ or individual paragraphs that start with “Note:” The keywords “shall“ and “shall not“ indicate requirements strictly to be followed in order to conform to the document and from which no deviation is permitted.
14、The keywords, “should“ and “should not“ indicate that, among several possibilities, one is recommended as particularly suitable, without mentioning or excluding others; or that a certain course of action is preferred but not necessarily required; or that (in the negative form) a certain possibility
15、or course of action is deprecated but not prohibited. The keywords “may“ and “need not“ indicate courses of action permissible within the limits of the document. The keyword “reserved” indicates a provision that is not defined at this time, shall not be used, and may be defined in the future. The ke
16、yword “forbidden” indicates “reserved” and in addition indicates that the provision will never be defined in the future. A conformant implementation according to this document is one that includes all mandatory provisions (“shall“) and, if implemented, all recommended provisions (“should“) as descri
17、bed. A conformant implementation need not implement optional provisions (“may“) and need not implement them as described. Unless otherwise specified, the order of precedence of the types of normative information in this document shall be as follows: Normative prose shall be the authoritative definit
18、ion; Tables shall be next; followed by formal languages; then figures; and then any other language forms. 3 Normative References The following standards contain provisions that, through reference in this text, constitute provisions of this standard. At the time of publication, the editions indicated
19、 were valid. All standards are subject to revision, and parties to agreements based on this standard are encouraged to investigate the possibility of applying the most recent edition of the standards indicated below.

24、e 2 shows the Type 2 10-bit multiplex resulting from mapping modes in which each data stream has two instances of TRS words, Line Numbers, CRC Words, etc. A type 2 multiplex is the result of SMPTE ST 292-1 mapping of each sub image. It is generated for 4:2:2 10-bit formats with frame rates of 30fps

This standard requires the use of the 75-ohm connector defined in Annex A of this reference. 2 Please note that this reference is required ONLY to provide mechanical dimensions of 75 ohm connectors.
