3、f 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 continents. SMPTEs Engineering Documents, including Standards, Recommended Prac

4、tices, 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-developing organizations, including ISO, IEC and ITU. SMPTE Engineering Documents a

5、re drafted in accordance with the rules given in its Standards Operations Manual. SMPTE RP 2089 was prepared by Technology Committee 31FS. Intellectual Property At the time of publication no notice had been received by SMPTE claiming patent rights essential to the implementation of this Engineering

6、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. Introduction This section is entirely informative and does not form an integral

7、part of this Engineering Document. The Entertainment ID Registry (EIDR) Identifier (as specified in SMPTE RP 2079) is used for global unique identification of movie and TV content. It is desirable to associate EIDR Identifiers with essence across applications of the MXF file format, without modifica

8、tions to these applications, and both at and after initial file creation. This can be achieved using the Descriptive Metadata Scheme plug-in mechanism specified in SMPTE ST 377-1. A Basic Application, specified in Section 5, is used when a single EIDR Identifier is associated with an output timeline

9、 of an MXF file. More complex applications, specified elsewhere, can associate multiple EIDR Identifiers with a file. For instance, a distinct EIDR DM Framework Set, and hence EIDR Identifier, can be associated with individual File Packages if the MXF file is a composite of multiple individual progr

10、ams. SMPTE RP 2089:2014 Page 3 of 6 pages 1 Scope This Recommended Practice specifies a Descriptive Metadata Scheme (as specified in SMPTE ST 377-1 and SMPTE ST 377) that allows an EIDR Identifier (as specified in SMPTE RP 2079) to be associated with essence contained in an MXF file. It also specifi

11、es a set of constraints to be used when a single EIDR Identifier is associated with an entire MXF file. 2 Conformance Notation Normative text is text that describes elements of the design that are indispensable or contains the conformance language keywords: “shall“, “should“, or “may“. Informative t

12、ext 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, except: the Introduction,

13、 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, “should“ and “should not“ i

14、ndicate 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 action is deprecated but not

15、 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” indicates “reserved” an

16、d 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 implementation need not

17、 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 definition; Tables shall be next; followed by fo

18、rmal languages; then figures; and then any other language forms. 3 Normative References The following standards contain provisions which, through reference in this text, constitute provisions of this recommended practice. At the time of publication, the editions indicated were valid. All standards a

19、re subject to revision, and parties to agreements based on this recommended practice are encouraged to investigate the possibility of applying the most recent edition of the standards indicated below.

Note: Canonical

28、 EIDR Identifier Type is specified in SMPTE RP 2079. It is derived from CanonicalDOINameType, which is itself derived from UTF16String type. 5 Basic Application This Section specifies the Basic Application of the EIDR DM Scheme that applies when a single EIDR Identifier is associated with an output

29、timeline of an MXF file. Other specifications or future revisions of this specification may specify additional applications of the EIDR DM Scheme.

The DM Segment shall conform to the following: o The Track IDs item shall be omitted; o The DM Framework item shall refere

33、nce one and only one EIDR DM Framework Set as specified in Section 4.3. Note: The Simple DM Plug-In Instance Removability specified in SMPTE ST 377-1 can be used to facilitate removal of the EIDR DM Framework instances. Additional EIDR DM Framework Sets, and hence EIDR Identifiers, may be associated with other aspects of the file, as provided in SMPTE ST 377-1.
