11、word ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical
12、committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in
13、the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of the joint technical committee is to prepare Internatio
14、nal Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. Attention is drawn to the possibility that some of th

ITU-T T.802 (2005)/Amd.1 (04/2010) 9) The media data in the Media Data Box(es) shall be placed within the box(es) in temporal order. 10) If more than one track is present, the media data for the tracks shall be interleaved, with a granularity no greater than the greater of (a)
26、 the duration of a single sample (in file format terms) or (b) one second. 11) The transformation matrices used are restricted to uniform scaling and rotation by multiples of 90. Table A.1 Audio format specification for archive preservation format Supported data format raw (optional MPEG-4 SLS). Sup
27、ported sample rates Each Motion JPEG 2000 decoder shall support sample rates of 48 kHz, 44.1 kHz, 32 kHz and 96 kHz (as recommended in 2). A Motion JPEG 2000 encoder can use any desired sample rate. However, without any further agreements outside the scope of this Recommendation | International Stan
28、dard, correct decoding can be assumed only if the values recommended above are being used. Supported word lengths Each Motion JPEG 2000 decoder shall be able to correctly decode word lengths of 16 and 24 bits. A Motion JPEG 2000 encoder can use any desired word length. However, without any further a
29、greements outside the scope of this Recommendation | International Standard, correct decoding can be assumed only if a word length of 16 or 24 bits is being used. Channel format Discrete (i.e., no matrix encoding). Audio data shall be stored in a lossless manner. For this purpose the raw audio forma
30、t shall be used. All audio channels shall be organized as discrete channels. As an option, audio data can also be represented as MPEG-4 Scalable Lossless Coding (SLS) specified in ISO/IEC 14496-3 as a compressed but lossless audio format. Metadata should be stored together with image and other media
31、 data in the same file. Metadata can consist of any combination of structural, descriptive and historical metadata. In all cases, there should be a minimum set of structural metadata stored. For image data this should consist of all information relevant to the employed JPEG 2000 encoding parameters
32、and contain at least image size, frame rate, colour space, sub-sampling information, number and meaning of components and bit depth. For audio data this should consist at least of bit depth, sample rate, number and meaning of audio channels for each multi-channel audio representation and audio encod

35、tinguished and selected by the alternate_group field. In addition, Edit Boxes (edts) and Edit List Boxes (elst) are permitted in order to create compositions of the different tracks. 4) The image codestream profile shall have Rsiz=5 or Rsiz=6 (as specified in ITU-T T.800 | ISO/IEC 15444-1, clause A.
36、10). 5) The XYZ color space as defined in ISO/IEC 26428-1 shall be used and signalled in the Colour Specification Box (colr) (as specified in ITU-T T.800 | ISO/IEC 15444-1, Annex I). 6) There is no restriction on frame rates. If distribution to digital cinema is intended, then frame rates of 24 fram
37、es per second (fps) or 48 frames per second (fps) are recommended. 7) The file shall be self-contained; no data references are used, and therefore all media data shall be contained within the single file. 8) The presentation shall be described by a single Movie Box (moov) only, i.e., fragments are d
38、isallowed. 9) The media data in the Media Data Box(es) is placed within the box(es) in temporal order. 10) If more than one track is present, the media data for the tracks is interleaved, with a granularity no greater than the greater of (a) the duration of a single sample (in file format terms) or
39、(b) one second. 11) The transformation matrices used are restricted to uniform scaling and rotation by multiples of 90.

Descriptive and historical metadata should be stored in an XML 9 representation. 3) Annex B Add the following clause: B.4 Digital cinema archives In this section practical guidelines for the use and application of motion picture archive form
45、ats are given. In the following paragraphs procedures are described that are meant to help in creating Archive Package files and how to use them to disseminate archived cinematic content to end users and to exchange archived materials between two or more archiving institutions. Implementations shoul
46、d be strict when writing, and tolerant when reading the described formats. B.4.1 Ingesting into cinematic archives Several ways exist to convert cinematic content to the motion picture archive formats. The content may come directly from various stages of an uncompressed digital production process or
47、 it can be a compressed digital distribution format, e.g., a Digital Cinema Package (DCP) 10. It is also possible to ingest images originating from scanned film material as well as access copies that were created through transferring original film images to some other type of analogue or digital med
48、ia, e.g., analogue or digital video tapes, digital versatile disk (DVD), etc. a) Ingesting uncompressed digitally produced material: Digitally produced material includes images that were recorded with an electronic camera and did not undergo any further processing, as well as the results of differen
49、t processing steps during post-production to the final cinematic product. This also includes scanned films that were subject of a digital restoration process. Common formats for this type of imagery are DPX 3, TIFF 4 or TGA 5 sequences. This type of material may also have its origin on a digital video tape format that has been ingested into a computer system. This type of material should be compressed using the JPEG 2000 profile for long-term storage of cinematic content. To be able to pre
