4、d 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, Recommended Practices, and Engineering Guidelines, are prepared by SMPTEs Technology Commi

5、ttees. 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 Engineering Documents are drafted in accordance with the rules given in its Standards Operations

6、Manual. SMPTE ST 2082-10 Document 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 this Standard.

Introduction SMPTE ST 2082-10 defines the mapping of various source images and associated ancillary data into a 12 Gb/s nominal SDI bit-serial interface.

8、The general process for creating 12G-SDI is illustrated below in Figure 1. Detailed definitions of how this process applies to each of the modes defined in the scope follow in other sections of this document. 1 2 G - S D I 1 0 - b i t i n t e r f a c e S T 2 0 8 2 - 11 2 G - S D I 1 0 - b i t M u l

11、es Formatting The source images are divided into two or four 1080-line sub images, depending on the format of the source image. The sub images are then mapped onto an 80-bit virtual interface consisting of eight 10-bit data streams. Each 10-bit data stream includes timing and sync words, line number

12、s, cyclic redundancy codes, ancillary data, including audio, and payload identification packets. Multiplex The 80-bit virtual interface is multiplexed onto a 12G-SDI 10-bit interface. The data streams are multiplexed in the order data stream eight, data stream four, data stream six, data stream two,

13、 data stream seven, data stream three, data stream five, data stream oneonto the 12G-SDI Link. SMPTE ST 2082-10:2015 Page 4 of 21 pages 1 Scope This Standard defines the mapping of: Mode 1: 2160-line Source image formats and ancillary data into a 12 Gb/s nominal SDI bit-serial interface This Standar

14、d also defines the carriage of the SMPTE ST 352 payload IDs for the 12 Gb/s SDI interface. It is not necessary for implementations to include support for all formats that are included in this Standard. Implementers should indicate supported formats in commercial publications. 2 Conformance Notation

15、Normative text is text that describes elements of the design that are indispensable or contains the conformance language keywords: “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 w

16、ithout affecting interoperability. Informative text does not contain any conformance keywords. All text in this document is, by default, normative, except: the Introduction, any section explicitly labeled as “Informative“ or individual paragraphs that start with “Note:” The keywords “shall“ and “sha

17、ll not“ indicate requirements strictly to be followed in order to conform to the document and from which no deviation is permitted. The keywords, “should“ and “should not“ indicate that, among several possibilities, one is recommended as particularly suitable, without mentioning or excluding others;

18、 or that a certain course of action is preferred but not necessarily required; or that (in the negative form) a certain possibility 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 ke

19、yword “reserved” indicates a provision that is not defined at this time, shall not be used, and may be defined in the future. The keyword “forbidden” indicates “reserved” and in addition indicates that the provision will never be defined in the future. A conformant implementation according to this d

20、ocument is one that includes all mandatory provisions (“shall“) and, if implemented, all recommended provisions (“should“) as described. A conformant implementation need not implement optional provisions (“may“) and need not implement them as described. Unless otherwise specified, the order of prece

21、dence of the types of normative information in this document shall be as follows: Normative prose shall be the authoritative definition; Tables shall be next; followed by formal languages; then figures; and then any other language forms. 3 Normative References The following standards contain provisi

22、ons that, through reference in this text, constitute provisions of this standard. At the time of publication, the editions indicated 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
