HDR/WCG Visualization & Testing
The adoption of High Dynamic Range (HDR) and Wide Color 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 colors to be displayed on a television screen. The combination of the two delivers content that is often more pleasing and immersive than broadcast television of today.
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 color space for broadcasters and technology manufacturers.
Simultaneously shooting live productions in both conventional Standard Dynamic Range (SDR) ITU-R BT.709 and High Dynamic Range (HDR) ITU-R BT.2100 with wide color gamut poses its own set of challenges. This is particularly true with a mix of SDR/709 and HDR/2100 sources be they Cameras, Replays or Graphics.
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.
