Foreword
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 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 matters 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 least 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 Picture 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.
ISO 26430 consists of the following parts, under the general title Digital cinema (D-cinema) operations:
⎯ Part 1: Key delivery message [equivalent to SMPTE 430-1]
⎯ Part 2: Digital certificate [equivalent to SMPTE 430-2]
⎯ Part 3: Generic extra-theater message format [equivalent to SMPTE 430-3]
⎯ Part 4: Log record format specification [equivalent to SMPTE 430-4]
⎯ Part 5: Security log event class and constraints [equivalent to SMPTE 430-5]
⎯ Part 6: Auditorium security messages for intra-theater communications [equivalent to SMPTE 430-6]
⎯ Part 9: Key delivery bundle [equivalent to SMPTE 430-9]

Introduction
This part of ISO 26430 comprises SMPTE 430-4-2008, together with Annex ZZ (which provides equivalences
between ISO standards and SMPTE standards referenced in the text) and the following additional information
related to subclause 6.1 (Record Text Extension Type) concerning the “RecordDescriptionText” element.
The optional language attribute is an xs:language language code and indicates the language used for
Record Description Text . If the language attribute is not present, the default value en is used.

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 continents. SMPTE’s Engineering Documents, including Standards,
Recommended Practices and Engineering Guidelines, are prepared by SMPTE’s 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 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 generate 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.

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 of 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 format 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", "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, 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 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 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
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 implemented, all recommended provisions ("should") as described. A conformant
implementation need not implement optional provisions ("may") and need not implement them as described.

3 Normative References

The Log Record Format standardizes the reporting format for information that documents 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 requireme
