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. This SMPTE Engineering Document was prepared by Technology Committee 35PM-50. EDITOR'S NOTE: URI values defined herein, e.g. http://www.smpte-ra.org/schemas/2065-20/xxxx, are temporary and will be replaced by their final values prior to publication, at which point this note will be removed. 1 Introduction A single TV or movie title is transformed into multiple content versions (airline edits, special edition, languages ) These versions, which share common assets sourced from high-quality source masters, are ultimately made available to multiple distribution channels (Internet, optical media, broadcast...) across multiple territories and over the span of many months to over a year. The IMF is a file-based framework that allows these high-quality versions, called Compositions, to be efficiently represented, managed and processed on file-based systems. For example, it facilitates the generation of multiple outputs of the same Composition (through instructions contained in an Output Profile List define in other documents) to accommodate the specific needs of distribution channels. Since management and processing of Compositions are performed across multiple devices and service providers, interoperability is desirable. Figure 1. The IMF framework allows the management and processing of multiple high-quality versions, called Compositions, of a finished content. 2 Scope This document defines Compositions for IMF Application #3, i.e. the parameters of Image/Audio/Data Essences, Track Files, and the constraints of Composition Playlist. It is based on Image Essence coded as a MPEG-4 Visual Simple Studio Profile codestream and Audio Essence coded as linear PCM. Compliant implementations need not implement all formats and format values, manufacturers are encouraged to indicate supported formats. 3 Conformance Notation Normative text is text that describes elements of the design that are indispensable or contains the Page 2 of 20 pages

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. Unless otherwise specified, the order of precedence of the types of normative information in this document shall be as follows: Normative prose shall be the authoritative definition; Tables shall be next; followed by formal languages; then figures; and then any other language forms. 4 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.

8.2 Virtual Tracks The following specifies constraints on virtual tracks (see SMPTE ST2067-3) present in a Composition. 8.2.1 Main Image Virtual Track A Composition shall contain exactly one Main Image Virtual Track. The Main Image Virtual Track shall consist of one or more MainImageSequence elements, as specified in Section A.1. If the underlying Image Essence is stereoscopic, as defined in Section 6.1.1.4, each MainImageSequence element shall contain Resource elements of type StereoImageTrackFileResourceType, as defined in Annex B, that reference two Track Files that conform to Section 7.2.. If the underlying Image Essence is monoscopic, as defined in Section 6.1.1.4, all MainImageSequence elements shall contain Resource elements of type TrackFileResourceType that reference Track File that conform to Section 7.2. The Edit Rate of the Resource elements shall be equal to the image frame rate of the underlying Essence. 8.2.2 Audio Virtual Tracks A Composition shall contain one or more Audio Virtual Tracks. Each Audio Virtual Track shall consist of one or more MainAudioSequence elements, as specified in Section A.2. Each MainAudioSequence element shall contain Resource elements of type TrackFileResourceType that reference Track File conforming to Section 7.3. The Edit Rate of the Resource elements shall be equal to the image frame rate of the underlying Essence. T.B.D. 8.2.3 Data Essence Virtual Tracks 8.3 Composition Edit Rate The Composition Edit Rate shall be equal to the edit rate of the Image Essence frame sample rate referenced by the Main Image Virtual Track. NOTE: The Composition Edit Rate does not constrain the rate at which implementations can reproduce a Composition. For instance, a Composition with an Edit Rate of 24/1 can be reproduced at 24,000/1,001 frames per second. 8.4 Track File Identification The TrackFileId element of TrackFileResourceType shall be equal to the Package UID value of the Top-level File Package. Page 18 of 20 pages

8.5 Segment Duration The duration of a Segment shall be greater than or equal to the duration of one Image Essence frame referenced by the Main Image Virtual Track. If the average number of audio samples per Composition Edit Unit is not an integer, the duration of each Segment shall be an integer multiples of 5/Composition Edit Rate. 8.6 Content Version A Composition Playlist instance shall contain at least one ContentVersion element. The Id element within each ContentVersion element may contain a valid URI. A scheme is shown in Table 22 for illustration. Table 22. Illustrative Content Version Id URI schemes (informative). UUID [RFC 4122] 8.7 EssenceDescriptor The File Descriptor structure (including Sub Descriptors) referenced by the top-level File Package of the Track Files referenced by the Composition Playlist shall be mapped to an EssenceDescriptor element using SMPTE ST 434:2006 [or https://www.smpte.org/apps/org/workgroup/31fs-ahg-reg_xml/]. 8.8 Digital Certificates T.B.D. 9 IMF Master Package (IMP) T.B.D.
