Rohde & Schwarz is expanding its R&S VTx video tester family to include tests for HLG-capable devices in line with the HDMI 2.0b standard. Hybrid Log-Gamma (HLG) is an enhancement to the high-dynamic range (HDR) technique that allows good-quality replay of state-of-the-art picture material even on non-HDR-capable devices. This is a crucial factor in the successful introduction of the spectacular HDR technique for a more intensive and realistic home theater experience.The R&S VTC/VTE/VTS video tester family is an innovative solution for testing the performance and interoperability of future generations of HDR/HLG-capable video consumer electronics. It is based on the recently introduced flexible T&M module for HDMI and HDR tests. The new module offers generator and analyzer functionality for data rates up to 18 Gbps as well as functions such as scrambling introduced with the new HDMI standard. Now it can also test HLG-capable devices. This includes testing and emulation of the signaling function and the generation of new test patterns.
The solution is downward compatible with HDMI 1.4 and supports HDCP 1.4 and HDCP 2.2. It covers real-time protocol testing and compliance testing in line with HDMI CTS 1.4/2.0, providing users with a test tool that can be used in various applications throughout the consumer electronics value chain.
