Other Products in This Suite

Visualizer test pattern screen

The Visualizer™ test pattern offers a comprehensive way to evaluate more than 20 key parameters of video quality from a single screen. Users can easily identify processing errors throughout the digital signal chain.

computer monitor with "VERIFY" on-screen

Using SRI’s Emmy® award-winning technology, the Sarnoff® Bitstreams™ suite is the de facto standard for systematically and unambiguously testing decoders against industry standards. It works in a matter of seconds and does not require a reference signal or specialized decoder.

audio console close up

AudioRef™ is a package of scientifically calibrated audio reference clips that enable professionals to accurately set up and evaluate audio monitoring equipment.

These decoder tests assess HEVC compliance and video processing performance any stage of the development cycle—from simulations to integrated products.

3D boxes floating out of tv monitor

SRI’s suite of 3D test patterns is specifically designed to test 3D signal chains, workflows, and displays. These tools allow users to easily evaluate and calibrate 3D video equipment by revealing errors visually.
