LYNX Technik’s HDR Suite of Processing Solutions for the greenMachine® platform addresses the challenge that broadcasters and content creators are facing when there is a need to broadcast or archive content in both SDR and HDR. The demand for more realistic and vibrant colors and enhanced dynamic range is ever-increasing. This creates a demand for broadcasters and media professionals to implement HDR solutions into their workflows to not only deliver enhanced content to the new HDR equipped displays, but more importantly to provide equally stunning content to the vast installed base of legacy SDR displays.

HDR Evie+ takes HDR to SDR conversion to a new level by the use of unique, industry leading dynamic segmented frame-by-frame algorithms that use sectional dynamic tone mapping that allows adjustment of each segment (144 segments/frame) of the 3G or 4K HDR content all in real-time. Using optimized HDR captured or produced program content, HDR Evie+ converts to SDR and retains exceptional detail in darker areas and preserves detail in bright areas that would be burned out by more basic HDR to SDR converters. Once configured, the process is totally automatic, analyzing and converting the incoming HDR image in 144 segments every frame; it requires no changes of the aperture of the camera or other operator intervention.

The segmented dynamic conversion by greenMachine HDR Evie+ is especially suited to demanding and unpredictable content, with fast moving subjects and high contrast conditions typically found in live sports and news broadcasts. Dynamic conversion offers an unprecedented opportunity because, on the one hand, the details in the lights and shadows are preserved in the SDR image, and on the other hand, a real dynamic adjustment can be made based on the HDR image.

The technology is both proprietary and patented, following years of research and development in close cooperation with Hochschule RheinMain University of Applied Sciences in Germany.
