HDR Evie+ is a Segmented Dynamic HDR to SDR Converter
HDR Evie+ converts HDR 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. It makes use of patented 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.
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.
LYNX Technik’s HDR Evie+ addresses the need for processing Live content (dynamically and automatically) from HDR cameras and converting the HDR content to SDR for viewing on SDR displays. It is an ideal HDR to SDR conversion tool for dynamically demanding and unpredictable content, such as live sports or news broadcasts. For this type of content, the analysis and corrections need to occur on a frame-by-frame basis to cope with challenging lighting conditions, brightness levels, and image composition. 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.
To do this, HDR Evie+ incorporates 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 HDR captured images, HDR Evie+ processes and brightens specific sections of the video signal, while at the same time retrieving details from over-exposed sections of the video. This is all accomplished in an automatic process, which analyzes and corrects the incoming HDR image on a segmented and frame by frame basis, and without any changes of the aperture of the camera.
All of LYNX Technik’s HDR to SDR processing solutions support a range of open standards for conversion, tone mapping, and color gamut, including HLG, PQ, SDR, and SLog3. They are powered by the greenMachine® titan hardware platform. Along with dynamic HDR conversions, greenMachine is also equipped with integrated frame synchronization, 4K/UHD up / down cross conversion, and a suite of powerful audio processing capabilities.
