The work of preparing International Standards is norm
8、ally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in t
9、he work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated
10、 to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible f

ISO 26428-9 was prepared by the Society of Motion Picture and Television Engineers (as SMPTE 428-9-2008) and was adopted, under a special “fast-track procedure”, by Technical Committee ISO/TC 36, Cinematography, in parallel with its approval by the ISO m

22、n 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
23、 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 paragraphs that start with “Note:” The keywords “shall“ and “s
24、hall 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 other
25、s; 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
26、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 defined in the future. A conformant implementation according to this
27、 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 them as described. 3 Normative References The following standar
28、ds contain provisions which, through reference in this text, constitute provisions of this standard. At the time of publication, the editions indicated were valid.

47、the digital interface according to this standard. A.2 The interval between the end of EAV and the start of SAV may be employed to convey HANC data packets 2 . A.3 The interval between the end of SAV and the start of EAV of any line that is outside the container boundary, as defined in 4.5, may be em
48、ployed to convey VANC data packets. A.4 ANC data packets may be conveyed across each of the X, Y and Z channels. A.5 The ANC data is defined by the most significant 10 bits of the 12-bit data and the least significant 2 bits shall be set to zero. A.6 Intervals not used to convey SAV, image data, EAV
