Sarnoff Test Sequence Generators with A/V Test Patterns for SD to 4K Video
SRI offers content creators, broadcasters, and distributors a comprehensive solution for testing and verifying the quality of digital video signal chains up to 4Kp60. The Sarnoff® audiovisual test sequence generator combines acclaimed digital test patterns with uncompressed playback hardware.
The TG-400™ player handles formats up to 4Kp60. It is a one-rack-unit, uncompressed video player that output 10-bit digital video and up to 16 channels of embedded digital audio.
The standard player includes three powerful test suites: the Visualizer™ video test patterns, AudioRef™ advanced audio reference clips, and ESP™ encoder stress patterns. Options include support for High Dynamic Range (HDR)/Wide Color Gamut (WCG) and UHD/4K testing as well as HDMI 2.0 output with HDR/WCG signaling for PQ and HLG. Users can also load their own content for testing. The result is a comprehensive, convenient, and cost-effective solution for quality control.
