Video Clarity’s ClearView Extreme 4K A/V Analyzer Makes European Debut

Latest Generation of Video-Quality Analyzer Measures Subjective Picture Quality in New 4K Formats


CAMPBELL, Calif. Sept. 4, 2013 Video Clarity Inc., provider of market-leading audio and video quality-assessment and analysis systems, today announced the European debut of its ClearView Extreme 4K video-quality analyzers. The analyzers provide a new level of input/output capability and performance in subjective picture-quality comparison for researchers in broadcast and consumer product manufacturing, as well as engineering departments in television broadcasting, cable, and IPTV program-delivery networks. In fact, several leading broadcast engineering groups have already adopted the solution to help maintain their leadership positions.

“With the continuing advancement of new coding algorithms for entertainment program delivery, new processing devices for flat panel televisions, and evolving compression schemes, the requirements of digital content distribution have increased dramatically,” said Adam Schadle, vice president of Video Clarity. “ClearView quality-analyzer solutions allow broadcast engineers and researchers to understand the generational and picture-quality potential of new 4K formats.”

The ClearView Extreme 4K analyzers are capable of interactive playback and comparison of two uncompressed 4K (3840 X 2160) sequences at up to 60 Hz in real time. With the easy-to-use ClearView solution, users can import and play A/V sequence files to compare processed video to original sources with new 8- and 10-bit high-resolution displays, and also to test for perceptual video quality. 

ClearView is a state-of-the-art test and measurement analyzer for A/V quality, subjective viewing, recording, and playing virtually any resolution of uncompressed sequences. ClearView provides various tools for assessing perceptual quality and performance of video and audio. The product line includes three full-reference scoring methods or scales, all of which are based on algorithms that have been developed to estimate perceived quality in a precise way. The results of those algorithms are then correlated against correctly produced subjective data under ITU-R BT.500.12. The result is a perceptual measure of subjective quality.

Video Clarity will demonstrate ClearView Extreme 4K at IBC2013 on stand 2.C57. More information is available at
