UHD has already brought us more pixels. The next logical step is not any additional pixels but better pixels that give a picture with more definition and, most important of all, improved colour reproduction and a higher dynamic range. Which is why the initials HDR (high dynamic range) and WCG (wide colour gamut) have been challenging those of UHD for prominence on booths at trade shows and in new TV sets advertisements.
By extending the dynamic range, more information can be accommodated in an image, bringing with it more dynamics in luminance to an image. In a similar way WCG allows more vibrant colours to be displayed because it can store a wider range of colour values than established RGB (Red Green Blue) colour spaces.
To further explain the challenges of HDR-WCG we have released a guide, developed from our successful webinar series on the subject, in which Peter Schut, our CTO and VP of R&D, provides a comprehensive explanation of the colour and imaging issues involved and how the broadcast sector might address these changes in the coming years. “Unlike other emerging technologies, HDR is a real game-changer, Schut claims. “It will provide a transformative viewing experience to the mass market and one that requires minimum effort from the viewer. As an industry, we need to provide better pixels and do it right first time. We have one chance and if we get it wrong audiences will switch off.” Read more on our technical guide here.
