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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
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 26429-9 was prepared by Technical Committee ISO/TC 36, Cinematography.
ISO 26429-9 was prepared by the Society of Motion Picture and Television Engineers (as
SMPTE 429-9-2007) 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 26429 consists of the following parts, under the general title Digital cinema (D-cinema) packaging:
⎯ Part 3: Sound and picture track file [equivalent to SMPTE 429-3]
⎯ Part 4: MXF JPEG 2000 application [equivalent to SMPTE 429-4]
⎯ Part 6: MXF track file essence encryption [equivalent to SMPTE 429-6]
⎯ Part 7: Composition playlist [equivalent to SMPTE 429-7]
⎯ Part 8: Packing list [equivalent to SMPTE 429-8]
⎯ Part 9: Asset mapping and file segmentation [equivalent to SMPTE 429-9]
⎯ Part 10: Stereoscopic picture track file [equivalent to SMPTE 429-10]

Introduction
This part of ISO 26429 comprises SMPTE 429-9-2007 and Annex ZZ (which provides equivalences between
ISO standards and SMPTE standards referenced in the text).

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 429-9 was prepared by Technology Committee DC28.

1 Scope
This document specifies a generic method for mapping a D-Cinema Package (DCP) onto one or more file
storage volumes. Data structures are specified which provide for the mapping of D-Cinema asset identifier
values onto paths within a particular file storage scheme (e.g., filesystem paths). Where required, assets may
be split across multiple storage volumes to allow efficient use of media and the mapping of assets larger than
a given storage volume’s capacity. The Asset Map and Volume Index structures and the associated
provisions detailed herein are intended to provide a framework for simplified mapping of a DCP onto a wide
variety of file storage systems.

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.
