7、(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 comm
8、ittee 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 electrote
9、chnical 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 memb
10、er 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
11、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

ISO 26429-3:2008(E) ISO 2008 All rights reserved 3SMPTE 429-3-2007 Page 3 of 9 pages 1 Scope This standard specifies the common features of the format of sound and picture Tracks Files for distrib
22、ution 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 Spec
23、ification 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, const

27、ndexed, 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).
28、 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 sma
29、ll 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
30、 combinations are beyond the scope of this standard. ISO 26429-3:2008(E) 4 ISO 2008 All rights reservedSMPTE 429-3-2007 Page 4 of 9 pages 4 Pattern Constraints 4.1 General D-Cinema Sound and Picture Track Files shall use the MXF file format SMPTE 377M in conjunction with the specialized Operation Pa
31、ttern, OP-Atom SMPTE 390M. Unless otherwise specified, Track Files shall follow the normative provisions of SMPTE 377M, SMPTE 390M and SMPTE 379M (Generic Container) and their references, notably SMPTE 336M (KLV). The full glossary of terms and acronyms used in the MXF specification is given in the
32、MXF File Format Specification. It is not repeated here to avoid any divergence of meaning. Readers unfamiliar with MXF are strongly encouraged to review the section of that document entitled “Definition of Acronyms, Terms and Data Types”. Implementers are cautioned that, although Track Files should
33、contain only those structures allowed by this document, SMPTE 377M nonetheless requires decoders to expect unrecognized (A.K.A. “dark”) KLV packets. Please review the section entitled “KLV Coded Dark Components” in SMPTE 377M for more information. 4.2 Baseline Operational Pattern In accordance with
34、SMPTE 390M, each Track File shall contain one Top-level File Package, representing the Track File in its entirety, and one Material Package. The Material Package shall not be used for playback but may be used to represent the offset and duration of the portion of the track intended for reproduction.
35、 SMPTE 390M, Annex A, gives examples of how OP-Atom MXF files can be used including the use of the Material Package tracks, Top-level File Package tracks and any lower-level Source Package tracks. 4.3 Additional Constraints 4.3.1 Container Track Files shall use the MXF Generic Container (GC) SMPTE 3
36、79M. Track Files shall use GC frame-based essence mappings. The Sound and Picture essence mappings shall be defined by associated mapping documents. 4.3.2 Interleaving Track files shall have a single essence type within the MXF Generic Container. Essence in Track Files shall be neither interleaved 1
37、nor multiplexed between essence types. 4.3.3 System Item The GC System Item is not used by Track Files. 4.3.4 Time Code track Time code tracks within the Essence Container are not used by Track Files. Synthetic time code is, however, present in the Header Metadata (see Section 6.2). 1From SMPTE 377M
38、: “multiplexed” means putting different partitions one after the other whereas “interleaved“ means that the Essence Container itself has different components which are interleaved on a time division basis. ISO 26429-3:2008(E) ISO 2008 All rights reserved 5SMPTE 429-3-2007 Page 5 of 9 pages 4.3.5 Par
39、titions A Track File shall have three partitions: Header, Body and Footer. The closed and complete Header Metadata shall be carried in the Header Partition, the Essence Container shall be contained in the single Body Partition and the Index Table Segment(s) shall be carried in the Footer Partition (
40、see Section 4.3.6 following). When possible, Sound and other Essence Partitions should have the same duration as the Picture Essence Partitions to which they relate. Track Files shall conclude with a Random Index Pack per SMPTE 377M. 4.3.6 Index Tables Track Files shall include standard MXF Index Ta
41、bles per SMPTE 377M. These Index Tables shall be divided into one or more Index Table Segments. NOTE Large VBR files may require multiple Index Table Segments due to segment space limitations. See SMPTE 377M for details. Each Index Segment shall be carried in the Footer Partition. 4.3.7 KAG Size Tra
42、ck Files shall employ the default KLV Alignment Grid of 1 see “Key Alignment Grid” in SMPTE 377M. 4.3.8 Essence Kinds Within a Track File, all Essence Containers of the same kind (Picture or Sound) shall be of the same essence type, e.g. JPEG2000, as defined by the relevant property of the essence d
43、escriptors. 4.3.8.1 Edit Rate All essence in a Track File shall have the same edit rate. 4.3.9 Encryption Track Files may include Essence Containers that have been subject to an encryption process. The Essence Container shall identify that the essence has been encrypted, but the definition of the en
44、cryption process is beyond the scope of this standard. 4.3.10 KLV Fill Track Files may use the KLV Fill item as defined in SMPTE 377M. 4.4 Labeling Track Files shall be labeled with a registered label, as per SMPTE RP 224, to identify the Essence Container and the Operational Pattern in every Partit
45、ion Pack and every Preface Set. The Essence Container label shall also be present in the File Descriptor. The Operational Pattern label shall be set according to SMPTE 390M. Since the Material Package within the Track File contains a single Source Clip (Section 4.2), Bit 0 of Byte 14 of the Operatio
46、nal Pattern label will always be 0. The value of Bit 1 of the same byte will depend on the number of essence tracks in the Material Package. ISO 26429-3:2008(E) 6 ISO 2008 All rights reservedSMPTE 429-3-2007 Page 6 of 9 pages 5 Essence Constraints The Track Files support a wide range of picture and
47、sound essence schemes and are, for instance, compression-agnostic. The following constraints exist independently of the particular essence scheme selected. 5.1 Picture 5.1.1 General Track Files are compression-agnostic. Each Content Package of the Picture Track Files essence container shall contain
48、one MXF GC Picture Item, each of which contains a single GC Picture Element. 5.1.2 Picture Parameters All frames in a Picture Track File shall share the same image structure. 5.1.3 Picture Packetization Picture essence shall be encoded in KLV Packets using a frame-based mapping and shall be indexed
49、accordingly. 5.2 Sound 5.2.1 General Track Files are sound format-agnostic. Each Content Package of the Sound Track Files essence container shall contain one MXF GC Sound Item, each of which contains a single GC Sound Element. 5.2.2 Sound Sampling All samples within a Sound Track shall have the same sample rate and bit depth. 5.2.3 Sound Packetization Sound essence shall be encoded in KLV packets using a frame-based mapping and shall be indexed accordingly. Where the soundtrack is multi-chann
