3、 pages SMPTE ST 2067-20:2016 Page 2 of 20 pages Foreword SMPTE (the Society of Motion Picture and Television Engineers) is an internationally-recognized standards developing organization. Headquartered and incorporated in the United States of America, SMPTE has members in over 80 countries on six co

4、ntinents. 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 closely with other standards-develo

5、ping organizations, including ISO, IEC and ITU. SMPTE Engineering Documents are drafted in accordance with the rules given in its Standards Operations Manual. SMPTE ST 2067-20 was prepared by Technology Committee 35PM. Intellectual Property At the time of publication no notice had been received by S

6、MPTE claiming patent rights essential to the implementation of this Engineering Document. 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 responsible for identifying any or all such patent rights.

7、SMPTE ST 2067-20:2016 Page 3 of 20 pages 1 Scope This document specifies Compositions for IMF Application #2. It is a specialization of the IMF Framework. Application #2 is meant for studio applications where a TV or movie title is transformed into multiple content versions (airline edits, special e

8、dition, languages) that are made available to multiple consumer distribution channels (Internet, optical media, broadcast.) across multiple territories and over the span of many months to over a year. It uses HD image essence coded as a JPEG 2000 codestream and audio essence coded as linear PCM. The

9、 transformation of Application #2 Compositions to the output formats appropriate for each distribution channel is specified in other documents. 2 Conformance Notation Normative text is text that describes elements of the design that are indispensable or contains the conformance language keywords: “s

10、hall“, “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 document is, by defau

11、lt, 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 deviation is permitted. T

12、he 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 certain possibility o

13、r 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 the future. The key

14、word “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 (“should“) as describ

15、ed. 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 authoritative definiti

16、on; Tables shall be next; followed by formal languages; then figures; and then any other language forms. SMPTE ST 2067-20:2016 Page 4 of 20 pages 3 Normative References The following standards contain provisions which, through reference in this text, constitute provisions of this standard. At the ti

17、me of publication, the editions indicated 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.
