UPGRADES 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,
January 06- Developing
perception-based quality assessment test and measurement tools, QoE
Systems, today released its version 2.5 of the 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
Walter van Hooff, 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, and 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 latest version include an
Extended Mode feature which enables the user to test video clips of 5
minutes length, or longer if required, to be able to capture all possible
impairments, it also has a new easy to use CLI.
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.
