9、s members in over 80 countries on six continents. SMPTEs 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 cooper
10、ates 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 Manual. SMPTE ST 2081-12 was prepared by Technology Committee 32NF.

Introduction SMPTE ST 2081-12 defines the mapping of various source images and associated ancillary data into a Quad-link 6 Gb/s nominal SDI bit-serial interface. The general process for creating a quad-link 6G-SDI is illustrated below in Figures 1 and 2. Deta
13、iled definitions of how this process applies to each of the modes defined in the scope follow in other sections of this document.

20、2081-12:2016 Page 5 of 46 pages The source images are divided to 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 stream includes timing an
21、d sync words, line numbers, cyclic redundancy codes, ancillary data, including audio, and payload identification packets. Multiplex The 160-bit virtual interface is then multiplexed onto four 6G-SDI 10-bit interfaces. The first four data streams are multiplexed in the order data stream four, data st
22、ream two, data stream three, data stream oneonto 6G-SDI Link 1. The second four data streams are multiplexed in the order data stream eight, data stream six, data stream seven, data stream fiveonto 6G-SDI Link 2. The third four data streams are multiplexed in the order data stream twelve, data strea
23、m ten, data stream eleven, data stream nineonto 6G-SDI Link 3. The fourth four data streams are multiplexed in the order data stream sixteen, data stream fourteen, data stream fifteen, data stream thirteenonto 6G -SDI Link 4.

This standard also defines the carriage of the SMPTE ST 352 payload IDs for the Quad-link 6Gb/s SDI interface. It is not necessary fo
26、r implementations to include support for all formats that are included in this Standard. Implementers should indicate supported formats in commercial publications. 2 Conformance Notation Normative text is text that describes elements of the design that are indispensable or contains the conformance l
27、anguage 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 without affecting interoperability. Informative text does not contain any conformance keywords. All text in this d
28、ocument is, by default, 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 devia
29、tion is permitted. 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 c
30、ertain 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 keyword “reserved” indicates a provision that is not defined at this time, shall not be used, and may be defined in
31、 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 document is one that includes all mandatory provisions (“shall“) and, if implemented, all recommended provisions (
32、“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 precedence of the types of normative information in this document shall be as follows: Normative prose shall be the au
33、thoritative definition; Tables shall be next; followed by formal languages; then figures; and then any other language forms.

34、74:2008) although, during a transitional phase, the document as published (printed or PDF) may bear an older designation (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 t
