Grass Valley validates camera technology with AJA HDR Image Analyzer 12G

Grass Valley, technology provider for the live media and entertainment industry, enables content providers to create, capture, and deliver live experiences. The company’s array of products, including a line of live broadcast cameras, power media centers, mobile production units, 24-hour newsrooms, and sports streaming platforms for global media brands.

To ensure its products comply with various industry standards, the company works with a range of manufacturers’ test and measurement equipment during its research and development (R&D). As part of its R&D process, Grass Valley recently leveraged AJA’s HDR Image Analyzer 12G to validate its technology for the LDX 150 live broadcast camera and the newly revealed LDX C135 compact camera.

During testing, the R&D engineer connected the camera being evaluated to an HDR Image Analyzer 12G and to an HDR monitor using single-wire 12G-SDI. To compare the outputs of two different cameras, an AJA Kumo SDI router was added to the setup, allowing for seamless switching between sources.

Each camera’s 4K/UHD output was sent to a monitor for visual evaluation and through HDR Image Analyzer, where the real-time signal analysis revealed technical information about the live signal. From there, the engineer could switch between camera sources and conduct an accurate color comparison using HDR Image Analyzer’s histograms, vectorscope, and HDR waveform monitoring features.

Grass Valley cameras and video processing technology are designed for compatibility across SMPTE SDI and 2110 standards, in HDR, SDR, Rec.2020, and Rec.709 color spaces, and are validated accordingly. AJA HDR Image Analyzer 12G allows the company’s engineering team to evaluate and test these parameters with a simple 12G-SDI interface and real-time analysis.
