8、onal Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been
9、 established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standa
10、rdization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for
11、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 for identifying any or all

ISO 26428-11 was prepared by the Society of Motion Picture and Television Engineers (as SMPTE 428-11-2009) and was adopted, under a special “fast-track procedure”, by Technical Committee ISO/TC 36, Cinematography, in parallel with its approval by the ISO member bodies.

Headquartered and incorporated in the United States of America, SMPTE has me
19、mbers 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 cooperates
20、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 Standard 428-11 was prepared by Technology Committee 21DC. Intellectual Property At the ti
21、me of publication no notice had been received by SMPTE claiming patent rights essential to the implementation of this Standard/Recommended Practice. However, attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. SMPTE shall not be held
22、responsible for identifying any or all such patent rights. Introduction This section is entirely informative and does not form an integral part of this Engineering Document. The frame rates currently standardized by the DC28 D-Cinema Technology Committee are 24 and 48 frames per second (fps). The hi
23、story of film making is littered with other frame rates ranging from less than 16 fps to 60 fps and beyond and there is considerable support for the making of films using readily available equipment made specifically for the film production market. This standard defines how implementations that conf
24、orm to the D-Cinema specifications can be extended to support the additional frame rates of 25 fps, 30 fps, 50 fps and 60 fps. ISO 2011 All rights reservedBS ISO 26428-11:2011 ISO 26428-11:2011(E)2BS ISO 26428-11:2011SMPTE 428-11-2009 Page 3 of 6 pages 1 Scope This standard defines additional frame
25、rates for D-Cinema that are in addition to the primary frame rates of 24 and 48 frames per second. These additional frame rates are defined to ensure that the artistic intent of the content producer can be maintained at the point of delivery. All other parameters defined by SMPTE 428-1, D-Cinema Dis
26、tribution Master (DCDM) Image Characteristics, remain as specified. This document is part of a suite of SMPTE engineering documents. This part defines the image characteristics of the additional frame rates individually at 25, 30, 50 and 60 frames per second, and also defines the resulting audio sam
27、ples per edit unit. Other parts will define further provisions to support the additional frame rates defined by this standard. 2 Conformance Notation Normative text is text that describes elements of the design that are indispensable or contains the conformance language keywords: “shall“, “should“,
28、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 document is, by default, normative, ex
29、cept: 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 deviation is permitted. The keywords, “sho
30、uld“ 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 certain possibility or course of actio
31、n 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 the future. The keyword “forbidden”
32、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 (“should“) as described. A conformant
33、implementation need not implement optional provisions (“may“) and need not implement them as described. 3 Normative References The following standards contain provisions which, through reference in this text, constitute provisions of this standard. At the time of publication, the editions indicated
34、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 recent edition of the standards indicated below.

36、l Cinema Distribution Master FPS (fps) Frames Per Second The following terms are used in this document: Edit Unit the smallest unit of D-Cinema content that can be successfully edited while maintaining the integrity of the content. The edit unit value must be an integer multiple of the duration of a
37、 single D-Cinema frame. In most cases, the edit unit value is the same as frame duration, but in certain applications, the value can be 1 (for example, stereoscopic D-Cinema requires an edit unit value twice that of the frame duration). Edit Rate the rate of edit units per second. Primary for the pu
38、rposes of this document, primary frame rates are those frame rates defined in SMPTE 428-1. 5 Additional Frame Rate Values The primary D-Cinema frame rates and levels shall be as defined by SMPTE 428-1. The additional frame rate values for D-Cinema use shall be 25, 30, 50 and 60 frames per second. Al
39、l additional frame rates shall be integer values. 5.1 Definition of AFR Levels The additional frame rates shall be defined in association with the picture size to form AFR levels as follows: Table 1 AFR Level Definitions AFR Level Maximum Horizontal Pixels Maximum Vertical Pixels Frames per Second A

Implementations may support any one or more of the AFR lev
41、els defined in Table 1. Implementations using this standard shall identify the values of AFR level that are supported. Note: The AFR level names use the prefix “AFR” to avoid confusion with the primary level values defined in SMPTE 428-1. ISO 2011 All rights reservedBS ISO 26428-11:2011 ISO 26428-11
