7、iiiForeword ISO (the International 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

8、a technical committee has been 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 matt

9、ers of electrotechnical standardization. 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 voting. Publication as an International Standard requires approval by at lea

10、st 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 such patent rights. ISO 26430-4 was prepared by the Society of Motion Pictur

11、e and Television Engineers (as SMPTE 430-4-2008) 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.

19、s reserved 1SMPTE 430-4-2008 Page 2 of 16 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

20、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-develop

21、ing 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 430-4 was prepared by Technology Committee DC28. Introduction Many devices in D-Cinema exhibition environments must g

22、enerate log records, which can record all manner of events in the normal and exceptional operation of systems. In order to achieve interoperability, it is desirable that log records are presented in a common basic format. ISO 26430-4:2009(E) 2 ISO 2009 All rights reservedSMPTE 430-4-2008 Page 3 of 1

23、6 pages 1 Scope The purpose of this document is to define XML structures and schema for individual log records and sequences of those records in D-Cinema applications. While not all log records require authentication, this specification provides for optional authentication of records and sequences o

24、f records, using digital signatures. Authentication requirements are established by separate application specifications. This document does not define a communications protocol, but is limited to specifying the structure and format of log records and their content. This document does not define a fo

25、rmat that devices must use internally, but it does define a format that is to be used when log records are interchanged with other devices. 2 Conformance Notation Normative text is text that describes elements of the design that are indispensable or contains the conformance language keywords: “shall

26、“, “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 default,

27、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. The k

28、eywords, “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 or co

29、urse 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 keyword

30、 “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 described.

31、A conformant 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.

32、ns indicated were valid.

37、ts the usage and behavior of a Digital Cinema system. This format is intended to be used for communicating log event information at such points in the system where interoperability or a common format is a requirement. This format may be used to construct records that are unidirectional in nature, me

38、aning that a bi-directional communications channel is not required in order to interpret the record content. However, additional efficiencies and features such as dynamic text internationalization can be achieved in a bi-directional communications environment. In order to provide for maximum flexibi

39、lity while maintaining interoperability, the Log Record format is designed to support a number of features which may be optional or required depending on any requirements which may be imposed by an application specification which uses this format. This format supports both authenticated and non-auth

40、enticated log records for security and non-security logging purposes, respectively. The format also supports record “sequences“, or Log Reports, to reduce authentication overhead, and provides for “filtering“ of authenticated record sequences in cases where it may be desirable to excise information

41、contained in Log Reports while preserving a record of that informations existence. In order to accomplish these objectives, the Log Record structure is broken down into three major sub-parts: Header, Body, and Signature, the first of which is required in a Log Record, and the second and third of whi

42、ch are optional. In addition, a number of fields in these sub-parts are optional for Log Records which are not required to support authentication, but available and may be required where authentication is a requirement. In Log Reports, some Body sections may be removed by filtering, so the Header is

43、 the only required part of a Log Record in a Log Report. The Log Record Header contains enough information to identify the source, time, and classification of the log record. It may also include hashes to support data integrity and authentication. Conceptually, the Log Record Header contains just en

44、ough information to support automated classification and sorting of log events, without revealing information that may be considered sensitive or non-public. The Log Record Body contains either the detail of the logged information in human-readable form, or index information to enable the translatio

45、n of the log detail into human readable form, or both. This includes all available information about the logged event, except that which is conveyed in the Log Header. The Log Record Body is not encrypted, but may be authenticated through a hash of its contents, which is contained in the correspondi

46、ng Log Record Header, which may be signed by a Log Signature. The (optional) Log Signature provides authentication of the header(s) of the current Log Record, or optionally authentication over a number of log records in a sequence. This document does not specify the internal format for log records k

47、ept within a device. Rather, this document specifies the format for producing authenticated log records, if a device is required to do so.
