Automated HDR to SDR Conversion

LYNX Technik, the provider of modular signal processing interfaces, has announced that HDR Evie+ is now available for its greenMachine platform.

LYNX Technik’s HDR Suite of Processing Solutions (HDR Evie+, HDR Evie, HDR Static) 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 simple solution is to have two independent production routes for SDR and HDR, but this is costly and falls short of delivering full HDR content to the customer and ultimately the subscriber / viewer.

The greenMachine suite of HDR processing tools addresses the issue of the simultaneous workflows by combining optimized HDR with up-converted SDR sources into a single HDR production process, thus eliminating the expensive and time-consuming dual SDR & HDR production.

HDR STATIC, HDR Evie (Enhanced Video Image Engine) and HDR Evie+ processing applications run on the now familiar and award-winning LYNX Technik greenMachine hardware platform. These industry leading format conversion solutions ensure facilities can, for example, use a single greenMachine titan hardware module to up-convert four independent 3G SDR sources (e.g. SDR-only cameras, graphics, replays, external feeds, archives, etc.) to HDR in a variety of formats, and feed directly into the HDR production workflow. This conversion ensures that HDR content is delivered direct from the optimized HDR cameras without compromise. Once the content is ready for delivery / broadcast / streaming to clients and subscribers/viewers, greenMachine can down-convert one of the HDR program output feeds to SDR, ensuring media facilities can deliver content to both HDR-capable screens and to viewers who are still watching content in SDR.

HDR Evie+, the most recent addition to LYNX Technik’s HDR line-up for its award-winning greenMachine platform takes things to a new level. It makes use of patented, 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. 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.

The entire range of LYNX Technik’s greenMachine HDR < > SDR processing solutions support a range of open standards for conversion, tone mapping, and color gamut, including HLG, PQ, SDR, and SLog3. Rec709, Rec 2020, and camera standards by Panasonic, Sony, Arri, ACES, DCI-P3, RED and BMD.
