    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.
