Live HDR Video Broadcast Production

Abstract Among the multiple uses of HDR video, live events can get a big benefit from HDR video, especially when it is recorded outdoors with uncontrolled light conditions. HDR technology can provide a better adaptation of cameras to rapidly changing light conditions such as scenes that combine bright sunny areas with dark shadows (football), balls that fly with a very bright sky in the background (golf, football), extremely rapid changes in light conditions (subjective cameras in Formula 1, concerts with flashing lights), etc. All of these cases introduce two main technological challenges: the real-time factor that does not allow any manual intervention nor a computationally demanding image data processing step, and the fact that the end-to-end production pipeline has to preserve all the dynamic range information.
