HDR/WCG

High Dynamic Range (HDR) and Wide Colour Gamut (WCG) deliver
exciting possibilities for viewers but they also impose additional
challenges with respect to the management of video brightness
and colour space for broadcasters and technology manufacturers.

HDR/WCG visualization & testing

The adoption of High Dynamic Range (HDR) and Wide Colour Gamut (WCG) content is accelerating for both 4K/UHD and HD applications. HDR provides a greater range of luminance, with more detailed light and dark picture elements, whereas WCG allows a much wider range of colours to be displayed on a television screen. The combined result is more accurate, more immersive broadcast content.

While offering more engaging and realistic viewing for audiences, HDR and WCG also bring additional challenges with respect to the management of video brightness and colour space for broadcasters and technology manufacturers. To address these issues, an advanced set of visualization, analysis and monitoring tools is required for HDR and WCG enabled facilities, and to test video devices for compliance.

PHABRIX’s Qx series provides a comprehensive High Dynamic Range and Wide Colour Gamut toolset with new instruments to enhance the visualization and analysis of 4K/UHD and HD-SDI content to speed workflows. The HDR/WCG tools include a signal generator, CIE chart, luminance heat-map, vectorscope and waveform, all supporting Dolby PQ, HLG* and SLOG3* standards.

The programmable HDR Heat-map highlights luminance zones, and it’s ideal for adjusting the brightness of a picture. The seven programmable colour overlay bands can be used to quickly identify zones, such as shadows, mid-tones and specular highlights.

With all these new HDR/WCG capabilities, broadcasters gain much improved HDR visualization plus faster and more effective quality control.
