Headquartered and
4、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 Committees. Participation in these Committees is open to all
5、 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 Part XIII of its Administrative Practices. SMPTE ST 2048-2 was prepared by Techn
6、ology Committee 10E Intellectual Property At the time of publication no notice had been received by SMPTE claiming patent rights essential to the implementation of this Standard. However, attention is drawn to the possibility that some of the elements of this document may be the subject of patent ri
7、ghts. SMPTE shall not be held responsible for identifying any or all such patent rights. SMPTE ST 2048-2:2011 Page 3 of 10 pages 1 Scope 1.1 This standard defines the mapping of 2048 1080 pixel array into a 2200 sample 1125 line interface structure as defined in SMPTE ST 274. This standard specifies
8、: Pixel array structure, Digital Timing Reference Sequences (SAV, EAV) and Digital Representation for transmission with single link or multi-link SMPTE ST 292-1 or SMPTE ST 424. Recommended Location of the color VANC packet defined in 6.3 of SMPTE ST 2048-1. 2 Conformance Notation Normative text is
9、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 without affecting i
10、nteroperability. 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 “shall not“ indicate r
11、equirements 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; or that a certain
12、 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 keyword “reserved” i
13、ndicates 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 document is one tha
14、t 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. 3 Normative References Note: All references in this document to
15、other SMPTE documents use the current numbering style (e.g. SMPTE ST 274:2008) 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) ar
16、e functionally identical. The following standards contain provisions which, 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 a
17、re encouraged to investigate the possibility of applying the most recent edition of the standards indicated below.

19、tions are implemented (RGB, YCBCR, RGBA, YCBCRA, RFSGFSBFSor RFSGFSBFSA); and whether the pixel representation employs a depth of 10 bits or 12 bits It is not necessary for an implementation to support all formats to be compliant with this standard 4.2 This standard specifies multiple frame rate for
20、mats as shown in Table 1 in Section 5. 4.3 Annex A of this standard defines the Progressive segmented Frame interface structure. 5 Digital Sample Structure and Digital Reference Sequences (SAV, EAV) 5.1 The image pixel array of 2048 1080 is mapped into the active area of the interface as shown in Fi
