SRI Sarnoff’s comprehensive testing tools catch and identify errors throughout the digital signal chain. Built on five decades of video and broadcast experience, our suite of patterns and bitstreams ensures interoperability and digital video quality at every stage from pre-production through to consumption.
Test patterns and audio
Visualizer™ Digital Video Test Pattern
The Visualizer™ test pattern comprehensively evaluates more than 20 key parameters of video quality from a single screen. It can identify processing errors throughout the digital signal chain quickly and easily.
The Color Space and Monitor (CSM) Test Pattern Suite
The CSM Color Space and Monitor test pattern suite tests displays and image processing systems for color space correctness and performance. CSM’s “eyes-only” design reveals trade-offs made during conversion among various color spaces including High Dynamic Range (HDR) and Wide Color Gamut (WCG) systems.
ESP™ Encoder Stress Pattern
The sophisticated ESP™ video clip consists of specialized and complex artificial test patterns that stress various aspects of processing to reveal television encoder deficiencies.
AudioRef™ Scientifically Calibrated Audio Clips
Accurately set up and evaluate audio monitoring equipment with the AudioRef™ package of scientifically calibrated audio reference clips.
Bitstreams
Sarnoff® Bitstreams™ Decoder Compliance Tests
The Sarnoff® Bitstreams™ suite is the de facto standard for systematically and unambiguously testing decoders against industry standards. Our Emmy® award-winning technology works in a matter of seconds and does not require a reference signal or specialized decoder.
Sarnoff HEVC Format Bitstreams
Decoder tests assess HEVC compliance and video processing performance at any stage of the development cycle—from simulations to integrated products.
Test sequence generators
Sarnoff Test Sequence Generators with A/V Test Patterns for SD to 4K Video
Sarnoff audiovisual test sequence generators combine acclaimed digital test patterns with uncompressed playback hardware for testing and verifying the quality of digital video signal chains up to 4Kp60 using HDMI and Quad 3G-SDI.
