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.

  • [35PM] 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
