Ultra HD Forum showcases efficient HDR/SDR and sustainability demos at IBC 2023

For its seventh-year at the IBC Show, the Ultra HD Forum presents three innovative demo pods at booth 10.C09. Central to this year’s demos is the efficient delivery of HDR and SDR, especially for live events.

  • Efficient, Sustainable Ultra HD: Single-master workflows for SDR/HDR are spotlighted. Emphasis is on preserving creative intent across HDR, SDR, UHD, and HD.
