QoE Systems LAUNCHES Q-MASTER FOR HD VIDEO; QUALITY ANALYZER FOR NEXT GENERATION VIDEO SERVICES

New Instrument Provides Perceptual Assessment Algorithms for HD Video Interfaces To Test and Measure Quality of HDTV Services

Los Altos, CA – June 11 – Developing perception-based quality assessment test and measurement tools, QoE Systems, today unveiled its Q-Master™ HD Video quality analyzer. The Q-Master solution is designed for telecommunications development engineers within System OEMs and Service Providers that need a flexible and cost-effective solution to test, measure and analyze the video quality generated and received by their multimedia products. A tool for laboratory environments, the Q-Master system uses ITU standard perceptual analysis to generate a Mean Opinion Score (MOS) that represents the end-user’s perception of quality from the device under test. These devices include codecs, echo-cancellers, real time encoders and trans-coders, head-ends, set top boxes and other types of video networking equipment.

“The use of perceptual measurement algorithms enables System OEMs and Service Providers to test, measure and analyze the quality of the multimedia produced by their products from the end-users perspective,” said Aart Konynenberg, Vice President of QoE Systems. “This unique measurement approach combined with Q-Master’s flexibility and Microsoft Windows®-based user interface sets a new standard for quality test and measurement analyzers.”

The Q-Master HD Video system has all the commonly used digital interfaces (GB Ethernet, SDI/HDSDI, HDMI) and uses an industry proven objective perceptual video quality algorithm. It is therefore unique in its capability to assess HD video quality as perceived by the viewer. The system has two main components – an I/O interface unit and a Windows-based network drive mapping application. The interface unit is easily portable and can be configured for multiple technologies, it can both originate and terminate 10/100/1000 Ethernet, SDI/HDSDI, HDMI. This approach means that the interface unit can be installed anywhere in the network and be controlled by any authorized client PC.

Q-Master Video provides the following measurement parameters: an overall MOS score, Blocking, Blurring, Jerkiness, PSNR, and PSNR vs. time, lost frames and/or packets, and many others. Additional algorithms will soon be available for no-reference video, lip-sync, etc. The Windows-based GUI provides many graphics and a video playback that enables quick and comprehensive quality assessment analysis.
