Headquartered and incorporated in the United States of America, SMPTE has members in over 80 countries on six continents. SMPT

9、Es Engineering Documents, including Standards, 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 organizat

10、ions, including ISO, IEC and ITU. SMPTE Engineering Documents are drafted in accordance with the rules given in its Standards Operations manual.

19、neralized process as used by Mode 2 and Mode 3 Formatting The source images are divided into four or sixteen 1080-line sub images as appropriate to the source image format. The sub images are then mapped on to a 160-bit virtual interface consisting of sixteen 10-bit data streams. Each 10-bit data st

20、ream includes timing and sync words, line numbers, cyclic redundancy codes, ancillary data, including audio, and payload identification packets. Multiplex The 160-bit virtual interface is multiplexed onto two 12G-SDI 10-bit interfaces. The first eight data streams are multiplexed in the order data s

21、tream eight, data stream four, data stream six, data stream two, data stream seven, data stream three, data stream five, data stream one onto 12G-SDI Link 1. The second eight data streams are multiplexed in the order data stream sixteen, data stream twelve, data stream fourteen, data stream ten, dat

SMPTE ST 2082-11:2016 Page 5 of 42 pages 1 Scope This Standard defines the mapping of: MODE 1: 4320-line YCBCR 4:2:2 and 4:2:0 10-bit image formats and ancillary data into a Dual-link 12 Gb/s nominal SD

24、nk 12 Gb/s nominal SDI bit-serial interface This Standard also defines the carriage of the SMPTE ST 352 payload IDs for the Dual-link 12Gb/s SDI interface. It is not necessary for implementations to include support for all formats that are included in this Standard. Implementers should indicate supp

25、orted formats in commercial publications. 2 Conformance Notation 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 i

26、ndispensable, 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 default, normative, except: the Introduction, any section explicitly labeled as “Informative“ or individual

27、 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. The keywords, “should“ and “should not“ indicate that, among several possibilities, one is recommended

28、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 or course of action is deprecated but not prohibited. The keywords “may“ and “need not“ indicate course

29、s 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 keyword “forbidden” indicates “reserved” and in addition indicates that the provision will never be defin

30、ed 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 described. A conformant implementation need not implement optional provisions (“may“) and need not implement

31、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 definition; Tables shall be next; followed by formal languages; then figures; and then any other language form

33、(such as SMPTE 274M-2008). Documents with the same root number (e.g. 274) and publication year (e.g. 2008) are functionally identical. The following standards contain provisions that, through reference in this text, constitute provisions of this standard. At the time of publication, the editions ind
