Test Pattern Options for Video Clarity’s ClearView Analyzers and ClearView Players

Visualizer™ Digital Video Test Pattern

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.

The pattern is available as an uncompressed video sequence, pre-loaded on a ClearView Analyzer or ClearView Player product or as an upgrade via delivered ClearView Library folder applied to a specific ClearView system.
