HDR Downmapping

Helps to improve the use of HDR Downmappers in live TV production

This activity is part of the EBU Video Systems & Workflows group and was created following the EBU HDR Workshop at SWR in May 2022, to help optimize the use of HDR to SDR downmappers in live TV production.

Currently the following deliverables are planned (green indicates the deliverable has already been delivered). Note that deliverables are dependent on enough participation in the work, and that the planning is subject to change.
