Headquartered and
5、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
6、 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 its Standards Operations Manual. SMPTE ST 429-14 was prepared by Technology Comm
7、ittee 21DC. 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 rights. SM
8、PTE shall not be held 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. This document specifies a method for carrying data essence in the MXF Generic Container for use in a D-C
9、inema Package. This specification is intended to place minimal constraints on the type of data to be carried or how it is used. In order to decode data packaged using the specification, additional information will be needed. While the specification is written to allow synchronization of the data tra
10、ck with picture or sound, the synchronization mechanism is outside the scope of this document. The abbreviation “aux” is used in place of the word “auxiliary” throughout the document, but the terms are interchangeable. The term “aux” is preferred. SMPTE ST 429-14:2014 Page 3 of 10 pages 1 Scope This
11、 standard specifies the mapping of unspecified data into the Data Element of the MXF Generic Container for use within a Digital Cinema Package. The MXF Generic Container (GC) is described in SMPTE ST 379. This standard specifies the Key, the Length and the Value fields of the Aux Data Element. This
12、standard also defines the Essence Container and the Essence Descriptor. This standard defines the SMPTE ST 429-7 Composition Playlist asset type extension required for inclusion of an Aux Data track. 2 Conformance Notation Normative text is text that describes elements of the design that are indispe
13、nsable 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 interoperability. Informative text does not contain any conf
14、ormance 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 requirements strictly to be followed in order to conform to
15、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 course of action is preferred but not necessarily required
16、; 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” indicates a provision that is not defined at this time, shal
17、l 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 that includes all mandatory provisions (“shall“) and, if imple
18、mented, all recommended provisions (“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 foll
19、ows: Normative prose shall be the authoritative definition; Tables shall be next; followed by formal languages; then figures; and then any other language forms. 3 Normative References Note: All references in this document to other SMPTE documents use the current numbering style (e.g. SMPTE ST 377:20
20、04) although, during a transitional phase, the document as published (printed or PDF) may bear an older designation (such as SMPTE 377M-2004). Documents with the same root number (e.g. 377) and publication year (e.g. 2004) are functionally identical. The following standards contain provisions which,
21、 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 are encouraged to investigate the possibility of applying the most recent ed
22、ition of the standards indicated below.
