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.
ISO 26429-3 was prepared by the Society of Motion Picture and Television Engineers (as
SMPTE 429-3-2007) 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
⎯ Part 4: MXF JPEG 2000 application
⎯ Part 6: MXF track file essence encryption
⎯ Part 7: Composition playlist

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 429-3 was prepared by Technology Committee DC28.

1 Scope
This standard specifies the common features of the format of sound and picture Tracks Files for distribution of
D-Cinema content using the MXF file format. It defines data structures for interchange at the signal interfaces
of networks or storage media, but does not define internal storage formats for compliant devices or mappings
for particular essence encodings. This document is an Application Specification for D-Cinema applications. It
is based on the SMPTE 390M OP-ATOM standard, but is further constrained to address the needs of
distribution of D-Cinema content to exhibition sites.

2 Normative References
The following standards contain provisions which, through reference in this text, constitute provisions of this
standard. At the time of publication, the editions indicated were valid. All standards are subject to revision,
and parties to agreements based on this standard are encouraged to investigate the possibility of applying the
most recent edition of the standards indicated below.

3 Overview
A D-Cinema Sound and Picture Track File is an indexed, randomly-accessible MXF container for a single clip
of a single essence track. D-Cinema Sound and Picture Track Files shall not contain interleaved, multiplexed,
multi-scene or multi-format essence.

This standard is implemented as a set of restrictions on SMPTE 377M (MXF) and 390M (OP-ATOM). These
restrictions fall in four broad categories:

• Pattern (in this case, a restricted version of SMPTE 390M OP-ATOM)

• Essence (in this case, an essence container that complies with SMPTE 379M)

• Header Metadata (in this case, strict compliance with SMPTE 377M)

• Descriptive Metadata (in this case, a small set of essential data)

This standard is not a complete specification of a Track File for a particular essence type. It is intended to be
combined with a standard essence mapping, essence constraints and optional encryption container to form a
complete specification. These standards and respective combinations are beyond the scope of this standard.
