Press Release Summary: The Video ValidatorT 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.

Press Release Body: IBC, RAI Amsterdam, September 7, 2007, Booth 1.339A -
Pixelmetrix, the global expert in Preventive Monitoring for digital television and
IPTV networks, announces the launch of its Video ValidatorT at IBC 2007, Amsterdam.

The Video ValidatorT 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 ValidatorT 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 ValidatorT 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 ValidatorT 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.

At Booth 1.339A, Pixelmetrix will also showcase its new EndGameT, DVShift-S21, Video
ValidatorT, DVStor-Flashback and DVStor-DAS (Direct-Attached-Storage),
DVStation-IP³T, DVStation-MiniT, DVStorIP-GenT, DVB-H and DVB-S2.

Pixelmetrix develops a host of IPTV and Preventive Monitoring systems that offer
unique attributes and versatility, allowing operators to achieve end-to-end
visibility and keep tabs on their network architecture.
