HDR

High Dynamic Range

The EBU helps its Members use High Dynamic Range (HDR) to provide stunning images. This forms part of the work performed in the HDR Implementation Task Force, the HDR Downmapping group, and the Video Systems group.

2024 updates

- See the presentation from FranceTV on the production innovations the broadcaster is rolling out for the Olympics 2024.
- EBU Members can join the special '2024 Sports in HDR' calls organized by the EBU HDR Task Force to help make sure they cover key events in HDR optimally.
- In this (public) video Thomas Berglund (NRK) demystifies video levels and how to check them.
- Learn more about NRK's HDR journey in this (public) presentation given by Odd Erling Høgbert (NRK).
- An overview of the 2024 line-up of monitors available form a series of vendors is available in the following presentations: Canon, Flanders Scientific, SonoVTS, Sony, SWIT
- In March 2024 we organized an HDR monitors testing session at BBC R&D; the results will be published later.

HDR Workshop 2022

- In May 2022 a hands-on Workshop dedicated to HDR workflows was held at EBU Member SWR.
- This event was preceded by a number online HDR webinars in which we look at current HDR production workflows of NBC Universal, BT Sport, HBS, the BBC, and Sky UK. See the events list for more details.
- After the worksho, we organized a series of calls to help Members prepare for handling the FIFA World Cup in Qatar in HDR.

Exchange of XAVC test files

EBU Members are sharing UHD HDR material to validate the metadata generated by various production tools. EBU Members have access by joining the Video Systems group.

HDR test material

Test sequences recorded during the EBU HDR Workshop 2022 are available here (you will need to log-in first).

At the European Athletics Championships 2018, EBU Members and technical partners trialled UHD HDR HFR with NGA in a live setting. Test sequences of this event are available for technical tests. Conditions and more information you can find on the Test Sequences page.

Selected sequences of the RTS Montreux Jazz Festival 2017 project are available to EBU Members. If you are an EBU Member interested to receive a copy, please send us an e-mail.

How was the Montreux Jazz UHD HDR material created?

Watch the making-of video to understand how the material was created and what kind of learnings RTS obtained from the project. EBU Members may also want to watch the presentation given by Derya Aydemir (SRG/SRR) at the EBU Production Technology Seminar 2018.

The inaugural European Championships in summer 2018 provided a perfect opportunity to test several emerging technologies. This issue of tech-i looks at what was done in terms of both production and distribution, covering advanced video and audio formats and potential 5G approaches.

The advent of High Dynamic Range (HDR) and Wide Colour Gamut (WCG) video naturally leads to consideration of what constitutes a good monitor for use with such signals.
