Pixelmetrix, the global expert in Preventive Monitoring for digital television and IPTV networks, announces the launch of its Video Validator™ at IBC 2007, Amsterdam.

The Video Validator™ serves as a full reference video quality analyzer of video streams. The analysis comprises of a comprehensive collection of metrics including PSNR, MSE, MSAD and Video MOS. The system works with a reference image and a test image, and uses full reference algorithms to run video analysis. Full reference video stream analysis measures the differences between the Reference and Distorted Images. The reference image is the uncompressed and full quality source image, while the distorted image being used is the output of the image transformation engine; in this case, it could be a transmission channel, encoder or simply a compression algorithm. The Video Validator™ Video Stream Analyzer complements the VisualMPEG VQA by providing a common subset of metrics such as Blockiness, Blurriness and Video MOS.

In addition to this common subset, the Video Validator™ Stream Analyzer also provides additional metrics drawing on the full-reference analyzer model being utilized. These include PSNR (Peak Signal-Noise Ratio), Delta, MSE (Mean Squared Error) and MSAD (Maximum Sum of Absolute Difference).

“We continually enhance our current product lines and develop more of such cutting-edge evaluation tools for video compression systems and algorithms to help step up the competency and efficiency of the service providers. Now, with the Video Validator™ Video Stream Analyzer, we have a thorough file-based stream analysis and verification tool with extensive media formats support including YCbCr, AVI, MPEG4 and H.264,” said Danny Wilson, Pixelmetrix President & CEO
