High Dynamic Range 4K UHD Gets Full Test Run at the Alpine Ski World Cup in Italy Case Study (GVB-2-0699A-EN-CS) File size: 457.9 KB, posted May 03 2019 Global Production decided to also commit two LDX 86N cameras to shooting at 6X speed in order to create exciting images in super-slow motion. Grass Valley followed these sporting events, technically supporting Global Production, by providing spare equipment and giving support in the management of native live HDR.
The production included a Grass Valley 2 M/E Karrera and Kayenne K-Frame with 192 in and 96 out in 3G, configured in 2.5 M/E 4K UHD with HDR.
The LDX 86N Series delivers native HD, 3G and 4K images for the highest possible resolution and image clarity. The LDX 86N Series lets you grow into the formats you need tomorrow while buying only what you need today. With a daily, weekly or perpetual GV-eLicense upgrade path, you can move from any single speed HD/3G format to 4K from 3X HD speed to 6X HD/3X 3G speed and even a camera that can switch between higher resolution and higher frame rate. Optional high dynamic range (HDR) for single-speed operation is available via a perpetual GV-eLicense.
LDX 86 Series High Sensitive (HD/3G/4K/High-Speed with optional HDR)
The LDX 86 Series of cameras offer the perfect solution for all format requirements, especially when light sensitivity is of prime importance. Acquiring in native 1920x1080, the LDX 86 4K and LDX 86 Universe cameras use a unique closed-system process for 3840x2160 UHD where all of the processing takes place within the camera system. This delivers a 4K image with the highest light sensitivity available in any system camera, with images almost indistinguishable from native 4K acquisition in most applications.
The world's first self-contained high-speed cameras in a small form factor for space-constrained applications. As an extension to the LDX range of cameras, they produce the same level of quality from angles and in areas where high-speed cameras with a compact form factor are required.
LDX 82 Series (HD/3G with optional HDR)
A unique line of advanced imaging cameras built around Xensium-FT CMOS imagers. These cameras have the highest sensitivity and image performance across different video formats, while offering a new level of business flexibility by using one hardware platform with a flexible GV-eLicense software upgrade implementation.
With the addition of BT.2020 wide color gamut support and optional HDR support, these cameras provide an outstanding solution for all HD/3G applications.
LDX C80 Compact Series (HD/3G)
An extension to the LDX Series of cameras with an identical image performance and a comparable feature set but in a smaller mechanical package. They are the perfect companions to the LDX Series cameras and bring a new level of image performance and business flexibility for all applications where cameras with a compact form factor are required.
Creative Grading Technical Brief (TB-PUB-3-0810A-EN) File size: 1.4 MB, posted Apr 13 2022 The capture of high-quality camera images during live conditions can be very demanding. Whether indoors or out, the difficulties of adapting to the limitations of natural or artificial lighting and responding to rapid lighting changes are compounded by the artistic choices of a camera look, matching ambient or branded coloring, producing in multiple video formats, and of course satisfying unpredictable customer expectations all under high-pressure time constraints.
Using Creative Grading for Distributed Production Technical Brief (TB-PUB-2-0952A-EN) File size: 1.2 MB, posted Oct 19 2020 Camera shaders are a critical part of maintaining picture quality during the constantly changing conditions of a multicamera live production. In today's socially distanced environments, media production teams would like to reduce the number of crew members on-site by allowing the camera shaders to work off-site. But they still must maintain the responsive reaction times needed for live shading.
The Impact of New Production Formats and Workflows to Camera Control Whitepaper by Klaus Weber, Principal, Camera Solutions and Technology, (GVB-2-0608A-EN-WP) File size: 1.2 MB, posted May 28 2019 Today, camera control solutions in live broadcast productions are mainly used to adapt the camera's capabilities to a given light situation, and to achieve a certain "look" and style of the images. New formats such as high dynamic range (HDR), wide color gamut (WCG), 4K UHD, IP and simultaneous HDR/SDR or HD/4K UHD operations, require more agile controls. Now with more features to be controlled, managing the various settings becomes very difficult. A broadcast camera control solution that leverages the developments from grading applications used in post-production and other widely used image control applications, such as Photoshop, will benefit from new ideas and the new talents grown with these solutions. It's time for a change! This paper will explain the background of today's camera control solutions and show, based on extensive customer feedback, how it should develop in the future.
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.
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 its customers to choose the best approach for their specific production needs today, whether that be HD, 4K UHD or both, plus an easy upgrade path for tomorrow's demands with GV-eLicenses as production requirements change.
Image acquisition for live broadcast applications faces many challenges in a multiformat landscape. The increase in spatial resolution required by 4K UHD, in combination with the additional requirements of UHD standards, including a potential increase in frame rate and high dynamic range with good sensitivity and S/N ratio will require some compromises and design decisions on the part of manufacturers, and camera selection on the part of camera users.
Some of these new requirements, especially increased resolution, have a negative impact on some important image parameters, such as sensitivity, noise performance and dynamic range. Multiple flexible solutions can address these challenges, including native format switching. Grass Valley's industry-leading LDX 86 Series cameras provide solutions for all these challenges and uniquely provide comprehensive upgrade/downgrade paths that present flexibility that's unmatched in the industry. This background document will explain the latest developments in imaging technology and outline Grass Valley's latest solutions to these live broadcasting challenges.
