Physical layer compliance test solution for HDMI meets rising demands for UHR and HDR

Keysight Technologies, Inc. has released its improved physical layer compliance test solution for HDMI, delivering robust compliance and performance validation capabilities for transmitter [source] and cable devices. The Keysight Electrical Performance, Validation, and Compliance Test Solution for HDMI manage the growing complexity and bandwidth demands of modern HDMI applications, including UHD video, HDR content, and immersive audio experiences.

With the rising demand for 8K/12K video, HDR content, and high-speed connectivity, engineers face increasing challenges in maintaining signal integrity across HDMI interfaces. The recent release of the HDMI 2.2 test specification by the HDMI Forum presents more stringent compliance needs for transmitters and cables, highlighting gaps in conventional test coverage. Without robust validation tools, manufacturers risk costly redesigns and certification delays. As HDMI technology advances, the need for comprehensive, automated test solutions is crucial to ensure performance, reliability, and a faster time-to-market.

As the HDMI ecosystem develops to support higher resolutions, faster refresh rates, and increased bandwidth demands, this test solution for HDMI offers a fully automated and scalable platform for professionals in design, engineering, and compliance testing to validate device performance with confidence and precision. The new test solution provides a unified platform for automated electrical testing as specified in the HDMI 2.2 test specification, ensuring that device manufacturers can confidently validate product performance at the transmission and cable. In contrast, reception testing is introduced at a later stage.

The company's physical layer compliance test solution for HDMI meets the latest technical and procedural demands of the HDMI Forum. Designed for precision and efficiency, the solution integrates high-bandwidth measurement hardware with automated compliance workflows to manage complex test scenarios across transmitters and cables. The modular architecture of the solution supports flexible test configurations, while built-in diagnostics provide deep insight into the root causes of signal degradation. This allows design and validation teams to not only verify compliance but also optimise performance early in the development cycle.

Han Sing Lim, vice president and general manager of Keysight's General Electronic Measurement Division, said: "With the introduction of the Keysight Electrical Performance, Validation, and Compliance Test Solution for HDMI, our customers can accelerate time-to-market for next-gen consumer electronics while ensuring robust integrity and regulatory compliance. By incorporating the latest version of HDMI technology in our solution, we are enabling leading consumer electronics designers and manufacturers to continue to push the boundaries of digital display and multimedia performance."

Backed by the company's global expertise in compliance testing and proven in high-volume production environments, the new solution delivers a trusted path to certification readiness and superior end-product performance.
