SMPTEs Engineering Documents, including Standards, Recommended Practices, and Engineering Guidelines, are prepared by SMPTEs Technology Committees. Participation in these Committees

However, attention is drawn to the possibility that some of the elements of this document may be the sub
7、ject 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 part of this Engineering Document. An Advertising Digital Identifier (Ad-ID) is used to identify advertising conte
8、nt across media. It provides unique, managed identifiers for advertising content. It is desirable to facilitate interchange of Ad-ID Identifiers in MXF and other SMPTE engineering documents by unambiguously specifying their representation. An Ad-ID consists of an eleven or twelve character string. T
9、his string is divided into three parts: 1. a four-character alphanumeric Company Prefix; 2. a seven-character alphanumeric Unique Code; 3. a one-character Video Format Identifier (see Figures 1-3). Non alphanumeric (“special”) characters and spaces are not valid within the structure of an Ad-ID. htt
10、p:/www.ad-id.org/how-it-works/ad-id-structure provides additional background information on Ad-ID. SMPTE RP 2092-1:2015 Page 3 of 8 pages In the figures below, the character string Ad-ID has been omitted. Figure 1 Sample showing no media identifier, which signifies an Ad-ID for a Standard Definition
11、 Commercial Figure 2 Sample showing a media identifier of “H”, which signifies an Ad-ID for a High Definition Commercial Figure 3 Sample showing a media identifier of “D”, which signifies an Ad-ID for a 3D Commercial SMPTE RP 2092-1:2015 Page 4 of 8 pages 1 Scope This specification defines specific
12、text and binary representations for the Ad-ID identifier. It also defines dictionary entries, e.g. types and elements, for use in MXF and other KLV-based applications. 2 Conformance Notation Normative text is text that describes elements of the design that are indispensable or contains the conforman
13、ce 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 conformance keywords. All text in th
14、is 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 the document and from which no d
15、eviation 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; or that (in the negative form)
16、 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, shall not be used, and may be define
17、d 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 implemented, all recommended provisio
18、ns (“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 follows: Normative prose shall be th
19、e authoritative definition; Tables shall be next; followed by formal languages; then figures; and then any other language forms. 3 Normative Reference The following standard contains provisions that, through reference in this text, constitute provisions of this recommended practice.
