HDR: A Guide to High Dynamic Range Operation for Live Broadcast Applications Whitepaper by Klaus Weber, Principal, Camera Solutions and Technology, (GVB-1-0676B-EN-WP) File size: 3.6 MB, posted Dec 21 2018 This whitepaper explains the challenges and the best possible solutions to produce native 10-bit HDR in either HD or 4K UHD, and deliver that content in HDR and SDR simultaneously, as necessary, thanks to the high-quality conversion that can be done with a downmapping process. These solutions provide native support for both of today's worldwide standard: Hybrid Log-Gamma (HLG) and Perceptual Quantization (PQ or SMPTE ST 2084).
HDR is shaping up to be the next major advancement in the viewing experience, with consumers praising the image improvements and broadcasters working to find the best options for delivery. Grass Valley's HDR solutions allow our customers to choose the best approach for their specific production needs today, whether that be HD, 4K UHD or both, through an easy upgrade path with GV-eLicense if today's business model demands HD.
Grass Valley, a Belden Brand, offers a portfolio of HDR-enabled solutions that includes cameras, switcher frames, servers, routers, up/ downmapping cards and multiviewers. With these devices, broadcasters are able to produce native 10-bit HDR in either HD or 4K UHD and deliver that content in HDR and SDR simultaneously, as necessary, thanks to the high-quality conversion that can be done with a downmapping process.
HDR and the Broadcast Environment: Better Pixels Create Better Content Whitepaper by Chris Merrill, Product Marketing & Klaus Weber, Principal, Camera Solutions and Technology, (GVB-1-0661B-EN-WP) File size: 1.3 MB, posted Feb 28 2019 HDR is generally recognized as the next big thing in content delivery with an immediate perceivable benefit for the consumer. The ability to produce HDR content in HD removes the significant bandwidth requirements needed for HDR in 4K UHD and can be more quickly deployed.

With ever-increasing momentum, image acquisition for broadcast must adapt to new requirements for supporting signal formats. These include having to support live event progressive formats, increasing number of cameras, and increasing distances between cameras and control points.
Delivering exceptional image acquisition solutions, Grass Valley offers Xensium-FT imagers with the only lossless 1080p imaging that maintains full sensitivity. Grass Valley 3G Transmission systems are the most flexible and future-proof transmission solutions available that also offer direct integration with third-party long distance transmission systems.
LDX Series Cameras with Xensium-FT Imagers: A Superior Replacement for CCD Technology Whitepaper by Klaus Weber, Director of Product Marketing, Cameras, (GVB-1-0164A-EN-WP) File size: 1.1 MB, posted Oct 29 2014 While CCD technology was the best choice for imagers in broadcast applications for many years, the latest generation of CMOS imagers now offers a range of advantages over CCD. This includes better sensitivity in progressive video modes today, and the potential for higher resolution, extended dynamic range and higher frame rates in the future. CMOS is setting the new standard for high-end broadcast applications.
