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 26428-9 was prepared by the Society of Motion Picture and Television Engineers (as SMPTE 428-9-2008) 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 26428 consists of the following parts, under the general title Digital cinema (D-cinema) distribution master.

• Part 1: Image characteristics [equivalent to SMPTE 428-1]
• Part 2: Audio characteristics [equivalent to SMPTE 428-2]
• Part 3: Audio channel mapping and channel labeling [equivalent to SMPTE 428-3]
• Part 9: Image pixel structure level 3 — Serial digital interface signal formatting [equivalent to SMPTE 428-9]

The following part is under preparation:

• Part 7 Subtitle [equivalent to SMPTE 428-7]

Introduction

This part of ISO 26428 comprises SMPTE 428-9-2008 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 XIII of its Administrative Practices.

SMPTE Standard 428-9 was prepared by Technology Committee DC28.

1 Scope

This standard defines the formatting and constraints of the DCDM SMPTE 428-1 Level 3 image Pixel Structure for transmission over the 1.485Gb/s dual link serial digital interface SMPTE 372M or 3Gb/s interface SMPTE 424M. The Serial Digital Interface (SDI) container parameters for DCDM level 3 are given in Table 1.
