Wohler unveils new RadiantGrid Detect and Correct legalisation option

Wohler Technologies today announced the release of the new RadiantGrid Detect and Correct legalization option now featuring the unique RightHue algorithm. This new option for broadcast gamut processing on the RadiantGrid Intelligent Media Transformation Platform assures that all video output by the RadiantGrid platform meets strict gamut specifications. More specifically, the option ensures compliance with the restrictions on luminance and RGB levels defined by the Digital Production Partnership (DPP) and European Broadcasting Union (EBU).

“As the first deliverable developed for our new Detect and Correct architecture, this new broadcast gamut legalisation option further extends the RadiantGrid platform’s media transformation capabilities,” said Craig Newbury, vice-president sales, RadiantGrid. “In fact, this option represents the first, technically superior, file-based legalisation solution integrated at the point of transcode — reducing the cost and complexity of processing while simplifying and retaining an end-to-end file-based workflow.”

By enabling and automating processing entirely within the file domain, the RadiantGrid Detect and Correct legalisation option with RightHue eliminates the unscalable real-time bottleneck of baseband processing, and does away with generational degradation of additional decode-encode cycles required by baseband or outboard file-based solutions. It also allows facilities to forego nonlinear editor processing and to establish highly efficient and cost-effective processing that meets set parameters uniformly and accurately. When speed is of utmost importance, processing can be gridded for ultimate performance.

The new Wohler RightHue legalisation algorithm powering the RadiantGrid option is optimised for constant hue legalisation (gamut processing) to EBU-R103/DPP gamut specification, the dominant gamut requirement in Europe. RightHue delivers precise gamut control, maximising use of the allowed gamut without the hue distortion and/or overclipping typical of traditional legalisation solutions. Constant hue-gamut control is especially valuable for commercials, for which accurate colour reproduction can be critical to the value of the brand.
