Seminar – HDR for Live Production
With the advancement of camera and display technologies towards a higher dynamic range, the broadcast world is facing a change. High Dynamic Range (HDR) is one of the major topics in the television industry, perceived by the viewer as a visible improvement in image quality and has a greater impact on the viewing experience than the increase in resolution or frame rate.
As subject of a Master Thesis in cooperation with Broadcast Solutions and the Hochschule der Medien Stuttgart (HdM) different possibilities for the simultaneous delivery of SDR and HDR signals are to be tested.

Increasing the maximum brightness while reducing the black levels allows a more realistic reproduction of the image in difficult-to-control lighting conditions. If a scene contains areas that are both very bright and very dark, conventional Standard Dynamic Range (SDR) systems are currently reaching their limits.
Depending on the selected f-stop, only the bright image areas can be displayed correctly, whereby the details in the dark are no longer recognizable and vice versa. An HDR system is at best able to cover the image content completely without changing the f-stop due to the extended dynamic range.
For the foreseeable future, HDR will conquer the TV market on both the production and the consumer sides, but for the transitional period this means a coexistence of SDR and HDR technologies. The manufacturers have already integrated HDR with the standardized transfer functions Perceptual Quantizer (PQ) and Hybrid Log Gamma (HLG) into their product spectrum and developed individual workflows for simultaneous delivery.
As subject of a Master thesis in cooperation with the Hochschule der Medien Stuttgart (HdM) different possibilities for the simultaneous delivery of SDR and HDR signals are to be tested. For this purpose, a test setup with hardware from different manufacturers is designed and implemented.
