  • Exhibition Display Study Group Project Not Approved 0%
    Start date: 12/15/2022
    Scope: • The study group shall investigate the needs and wants of the various concerned parties – e.g., DCI, Exhibitors, Manufacturers, Distribution Partners, Installers, QC Testers, and any others affected by the expansion of Exhibition Display Technology. • The group will investigate the implications of both Projection and LED displays that now reach into the ITU-R Rec BT.2020 color space and using and ITU-R Rec BT.2100 transfer functions, for displaying up to 300 nits (possibly 500) and down to 5 millinits (or lower), and the implications of their use in various combinations and with various hardware and software in the current and future infrastructures. • The group will investigate the capabilities of this equipment for any instances where the inclusion of the new technologies might create errors in equipment less capable, whether electronic, mechanical or human. • The group will consider implications for the DCDM and DCP, possible flows upstream from Production and Post into Exhibition, and downstream into, as examples, IMF and archiving due to the the needs the expanded requirements, including metadata and naming conventions and if required bitstream and compression and communication to exhibition personnel and equipment. • The group will consider these implications for use in cinema auditoriums, review rooms, and possibly the general displays in executive suites used for review purposes. • The group will consider what documents might be affected or useful for revision to include new parameters, and also consider whether new documents might be more useable, including the case where many parts of older documents establishing metrics of older technologies (for example) might be better collated or harmonized into a new document. • The group’s report will outline the top-level details of the requirements of the various needs and implications of the new technologies influence, on potential SMPTE documents to revise and/or create, and also submit a organizing chart that could assist with the future flow of such document(s) revision or creation. • The work of the Study Group will not be constrained, excepting that 1. it is only to investigate, discuss, correlate and report. No test materials, sample bitstreams, sample software, data schemas, validation criteria, or problem decomposition shall be developed during the work of this Study Group Project. 2. There is a time limit on the Study Group of 6 months, including time for liaisons and writing the final report. • The Study Group Report will be Public.

  • ST 2067-206 IMF - Event-based, Text-based Metadata Plug-in WG or DG working on WD doc 20%
    Start date: 08/01/2022
    Scope: Develop a standard for an Interoperable Master Format (IMF) plug-in that defines: - a mechanism for adding a textual metadata document and associated binary resources to an IMF Composition where: • the metadata Track Files follow the same design approach as Timed Text Track Files (SMPTE ST 429-5) • there is a means specified (whether explicit or implicit) of optionally linking the metadata Virtual Tracks to other Virtual Tracks in the Composition - a simple scheme for generic event-based metadata for optional use within the metadata Track Files. The scheme shall: • have a minimal design specifying skeletons of events and (optional) shared objects • be specified in both XML and JSON • fit well into in an MXF/IMF context • not be tied to metadata for any particular use case Objections from TC review: - Proposal is incomplete - Project is assigned to the wrong TC Discussion: - The proposed scope is to develop a standard for an IMF Plug-in and the workstatement is complete. - The project is assigned to TC 35PM specialized in IMF related works. Resolution: - Added TC 31FS as a SMPTE Liaison - Accepted by commenter 2022-08-24 Project is approved on 2022-08-24 - No other feedback is received from TC and ST review
  • ST 2067-207 IMF - Video Viewports Metadata Plug-in WG or DG working on WD doc 20%
    Start date: 08/01/2022
    Scope: Develop a standard that extends the “Interoperable Master Format — Event-based, Text-based Metadata Plug-in” by defining: - metadata schemas (XML and JSON) for video viewports metadata that extend the “simple scheme for generic event-based metadata” - an appropriate mechanism (such as a new SubDescriptor) to enable Track Files carrying video viewports metadata to be distinguished using the details carried in an IMF CPL file. The metadata schemas shall: - allow the description of a number of ways to “experience” the associated video content, where each experience is specified by one or more “viewports” on the timeline. • A viewport is intended for display; it is a rectangular region of the associated video that is optionally rotated prior to display. - provide a mechanism for tagging the experiences and viewports, for example to allow the signalling of their content or intended use. Out of scope: - Specification of a dictionary of values for tagging - Mechanisms for describing how multiple experiences or viewports are to be combined/rendered Project is approved on 2022-08-08 - No comments received from TC and ST reviews

    Start date: 03/01/2022
    Scope: Develop a standard for an Interoperable Master Format (IMF) plug-in to allow ADM (Audio Definition Model, ITU-R BS.2076) metadata to be carried alongside PCM essence in IMF compositions, where the Track Files used are Audio Track Files (SMPTE ST 2067-2) augmented by ADM metadata in accordance with the output of the project “31FS-ST-Mapping ADM to MXF”.
  • ST 2131 Mapping ADM to MXF WG or DG working on WD doc 20%
    Start date: 03/01/2022
    Scope: Define a means of mapping audio metadata RIFF chunks to MXF with specific consideration of the requirements related to ADM metadata (for example, with reference to ADM carriage in BW64 files per Rec. ITU-R BS.2088-1). The target use cases would involve export of content to an MXF file at the end of an editing session, after format conversion, or similar. As such, any special considerations relating to in-place editing of MXF files are out-of-scope.
