Consequently, clearly specified file formats for each elementary file type are needed. 2. Each H.26L video encoding or decoding system capable of file output shall support the file format. 3. The file format is not supposed to replace any existing multimedia file format, such as QuickTime, MP4, ASF, or AVI. 4. (...) The file format shall be byte-oriented. 9. The file format should enable random access, fast forward, and fast backward operations. 10.

The changes compared to VCEG-O44 make the file format closer to the common ISO media file format currently used as a template for several standards such as MPEG-4, Motion JPEG 2000, and 3GPP. (...) It includes the specification of the interim file format. 2. List of Changes 2.1. Overview The structure of the file format proposed in VCEG-O44 is based on byte-aligned “clumps” similar to the definition of boxes in the ISO media file format. (...) Only ‘jvt ’ shall be used for majorBrand, as the file format is not compatible with any other format. tmlMajorVersion and tmlMinorVersion define the version of the TML document the file complies with.

This contribution proposes such a file format. We propose that H.26L encoders and decoders capable of video file output and input shall use the proposed file format. Section 2 discusses why existing a file formats are not suitable for H.26L and justifies the major design decisions of the proposed file format. (...) We examined the MP4 file format (in ISO/IEC 14496-1) that is closely related to the QuickTime file format.

Q.11/SG 16 has been discussing a H.324 file format during its last meetings. It was proposed during the Eibsee meeting in December 1997 to investigate the work on the Intermedia format within MPEG and to examine if this format is also useful for H.324. (...) Media-data is not ‘framed’ by the file format; the file format declarations which give the size, type and position of media data units is not physically contiguous with the media data. (...) When combined with the non-framing approach, it also makes it possible to include media data in files not formatted to this specification (e.g. ‘raw’ files containing only media data and no declarative information, or file formats already in use in the media or computer industries).

ITU Letter-Fax (English) - 2 - QUESTION ITU-R 34-3/6[footnoteRef:1] [1: This Question should be brought to the attention of ITU-T Study Group 9 and the ISO/IEC JTC1 SC29 Working Group 11.] File formats and transport for the exchange of audio, video, data and metadata materials in the professional broadcast environments (2002-2007-2009-2019) The ITU Radiocommunication Assembly, considering a) that storage systems based on information technology, including data disks and data tapes have already started to penetrate all areas of the professional television environment; production, non-linear editing, play-out, post-production, distributed production, archiving, contribution and distribution; b) that future TV production enviroments will increasingly incorporate systems from the Information Technology (IT) world such as networks, and server systems; c) that applications for professional TV and sound broadcasting are being increasingly based on software which generally handle content in file form; d) that file exchange does not introduce additional picture and sound quality degradation if, for example, the compressed audio and video accommodated in the file body is transferred in its original, compressed form; e) that file exchange can be adapted easily to the available channel bandwidth so that user can trade-off transfer-bandwidth versus transfer-time; f) that audio, video, data and metadata can be stored and transferred in a common file; g) that audio, video, data and metadata can also be stored and transferred as independent files with provision for later synchronization; h) that the technology of file formats and file exchange offers significant advantages ina workflow in professional broadcast environments; i) that the interoperability within and between content management systems is an essential user requirement for the exchange of content and assets; j) that the application of metadata exchange in TV and sound production requires support of existing specifications on metadata; k) that compatibility with both binary and XML metadata transport protocols needs to be considered; l) that the adoption of a small number of interoperable file formats for the exchange of broadcast content would greatly simplify the design and operation of equipment and facilities; m) that interoperability and conformance testing can be simplified when a single coding method is specified; n) that many broadcasters have already deployed systems based on file formats; o) that many applications provided by multiple vendors rely on interoperable file formats; p) that it is desirable that file formats meet future user requirements, recognizing a) that Recommendation ITU-R BT.1775 defines the editable file format and the generic container for the exchange of metadata, audio, video and data; b) that Recommendations ITU-R BS.1352 and ITU-R BS.2088 specify file formats for the exchange of audio programme materials with metadata, decides that the following Questions should be studied 1 What are the user requirements and potential category of requirements for carrying programme and programme genres for the exchange of audio, video, data and metadata encapsulated in a file format in the professional television and sound broadcasting environments? 2 What structure of file formats will best serve the future needs of users, while desirably maintaining interoperability with existing deployments? (...) 5 What digital interfaces should be specified for transport of the file format(s) for interchange of audio, video, data and metadata?
