Your Customers Are Scoring Your Video -- Are You?

Automated, Repeatable Video Quality Measurement Solution

CAMPBELL, CA--(Marketwire - December 5, 2007) - Video Clarity, Inc. has responded to the industry need for automated, repeatable video quality analysis. ClearView 5.0 combines its suite of objective quality measurement tools with Sarnoff's Just Noticeable Difference (JND) allowing video experts to play, capture, view, and quantitatively measure video sequences. This software upgrade is available to all existing customers and comes installed on all new ClearView Shuttle Broadcast, ClearView Shuttle DVI, ClearView Classic, and ClearView Extreme Video Analysis Systems.

To maintain quality as compression standards change, everyone along the chain needs to constantly measure the performance of the compression engines on which day-to-day operations depend. Any operation, large or small, from hardware/software designers to end user-producers who work with any kind of compression in standard or high definition, should subjectively and objectively analyze compression performance to know how their technical and aesthetic choices will look to end-users.

The simplest use of ClearView is to compare two video streams side-by-side on the same display under identical conditions, and decide subjectively which one looks better to you. However, this is all too dependent on your viewers.

ClearView includes the Sarnoff JND objective metric which mimics the human visual system and returns an objective score to indicate the quality of the video. These scores correlate with human viewers 75% of the time based on the Video Quality Experts Group -- VQEG research.

ClearView can be remotely controlled in batch mode or interactively controlled via the GUI. It compares the result of any of its metrics against a threshold generating a pass/fail condition. All of the results are logged and archived for later retrieval.
