For Immediate Release: Video Quality Test made easy and accurate with new instrument.

The new Q-Master2 test toolset with the ITU-T recommendation J.341 makes it easy to accurately and reliably determine video quality with a single measure.

Los Altos, CA. April 12, ‘12 : Video content distribution is exploding as video is becoming available on an ever increasing number and types of devices. All this video content is compressed somewhere in the stream. The video compression as well as many other signal processes along the line can, and often do, cause video quality degradation. To accurately and reliably measure the degradation QoE Systems (see http://www.qoesystems.com) has developed the tools to do this easily. With the help of an algorithm recently recommended by the ITU-T (recomm. J.341) the Q-Master2 toolset measures the video quality using a single metric: MOS (Mean Opinion Score). The MOS measures the video quality as perceived by an actual viewer.

ITU-T J.341:Recently (Jan.’11) the ITU-T has released their recommendation J.341 (http://www.itu.int/net/itu-t/sigdb/spevideo/Jseries-s.htm) , which is the most recent video quality test recommendation and includes psycho-visual metrics to accurately predict the MOS. This recommendation is for a proprietary algorithm, VQuad, which came out “head and shoulders” above any of the 14 candidate algorithms, including those from the leading companies working in this field (see http://www.its.bldrdoc.gov/vqeg/projects/hdtv/). The J.341 recommendation test scores have up to 92% correlation with subjective scores!

See J.341 in action at Booth SU4722 (QoE Systems) at NAB’12.

There are tools available to accurately measure video quality for all video formats, the first one on the market is the Q-Master2 toolset from QoE Systems Inc. now showing on booth SU4722. There are a number of applications for this technology and QoE Systems has developed an initial set of tools both software only, as well as a system solution, for immediate deployment. The J.341 uses the “full reference” methodology and incorporates many metrics accumulating into MOS. The Q-Master2 uses both predetermined video clips for test, but also enables the use of the algorithm for live streams with a “Real Time Reference” function. This makes it possible to accurately test & monitor broadcast signals.

QoE Systems Unveils Its Q-Master2 Software Suite for Video Quality Analysis.


Unique New Tool provides Perceptual Assessment for 2D & 3DHD Video using the ITU-T J.341 recommendation

Los Altos, CA, April 7: Developing test and measurement tools for QoE (Quality of Experience) applications, QoE Systems, Inc., today releases its Q-Master2™ Video SW suite for Video Quality Analysis. The Q-Master2 Software solution is designed specifically for codec developers and other developers who would use a file based toolset for test & analysis. The Q-Master2 software suite uses the just released ITU-T J.341 standard perceptual analysis recommendation to generate a Mean Opinion Score (MOS). The MOS represents the end-user's perception of quality from the device under test. These devices include codecs, transcoders, gateways, 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 their products from the end-user's perspective," said Walter van Hooff, President of QoE Systems. "This unique measurement approach combined with Q-Master2's flexibility and Microsoft Windows® based user interface sets a new standard for quality test and measurement analyzers."

Q-Master2 is the first tool that can accurately assess the video quality of 3DHD, together with SD and 2DHD video. It is file based and compares an uncompressed .avi reference clip to a de-compressed .avi test clip to than apply both traditional electro-visual metrics such as PSNR, etc. and psycho-visual metrics for blurring, blocking, jerkiness, etc. to generate an overall MOS (Mean Opinion Score). The tool enables an overall single metric (MOS) as well as the several other metrics to enable some root cause analysis of the video quality impairments. The tool allows for use on SD, 2DHD and 3DHD video.

Pricing and Availability: The Q-Master2 Software Suite is available today directly from QoE Systems for Video Quality Assessment starting at $18,990.00 for a single license.

QoE Systems Adopts the Latest ITU-T J.341 Standard.

The brand new ITU-T J.341 recommendation enables end-to-end video quality assessment using a unique approach

Los Altos, CA, April 6: Developing test and measurement tools for QoE (Quality of Experience) applications, QoE Systems, Inc., today announces that it is adopting the new ITU-T J.341 recommendation for the accurate assessment of video quality. Recommendation J.341 is unique, because for the first time the ITU recommends the use of psycho-visual metrics for the assessment of video quality, making the scoring process much more accurate and reflective of the end user perception of the video images. QoE Systems is incorporating the J.341 algorithm into its next generation Q-Master2 video quality test & analyzer product.

Many impairments to video quality are caused by video compression and bandwidth limitations, those impairments can only be accurately measured using psycho-visual principles. Traditional measures such as PSNR which have been used for decades, although still use-full, do not capture significant impairments such as blocking, tiling, blurring, etc, which can now be measured accurately using J.341.

"The use of perceptual measurement algorithms enables System OEMs and Service Providers to test, measure and analyze the quality of their products from the end-user's perspective," said Walter van Hooff, President of QoE Systems. "This unique measurement approach combined with Q-Master2's flexibility and Microsoft Windows® based user interface sets a new standard for quality test and measurement analyzers."

Q-Master2 is the first tool that can accurately assess the video quality of 3DHD, together with SD and 2DHD video. Q-Master2 Video provides the following metrics: an overall MOS score, Blocking, Blurring, Jerkiness, PSNR, and PSNR vs. time, lost frames and/or packets, and many others.

Pricing and Availability: Q-Master2 Video is available today directly from QoE Systems for Video Quality Assessment starting at $37,990.00.

QoE Systems launches QoE Monitor; quality of service monitoring system for multimedia services

New System Uses Standards-Based Psychoacoustic Models To Monitor Quality Of Service In Wired And Wireless Networks.

Las Vegas, CA, May 11, 2004: (Networld+Interop, Booth # 1959) Leaders in the use of ITU standards-based psychoacoustic models for Quality of Service (QoS) monitoring, QoE Systems Holding Inc. (QoE Systems ), today announced the introduction of the QoE Monitor QoS monitoring solution for multimedia communications services on hybrid networks. Designed for large enterprises and carriers that wish to reap the cost and advanced service benefits of converged voice and data networks, QoE Monitor uses a central control server with multiple remote agents to measure and track the QoS of voice and data communications throughout any IP, PSTN or wireless network. A key feature of the QoE Monitor system is that it uses a unique Mean Opinion Score (MOS) measurement technique based on ITU standardized psychoacoustic models to measure service quality from the end-user's perspective. The QoE Monitor system gives network operators the intelligence needed to reconfigure network elements, add bandwidth or do whatever is necessary to maintain the appropriate levels of service quality.

"Today's network management tools do not have the proper measurement and analytical capabilities needed to measure what the end-user is actually experiencing," said Walter van Hooff, President of QoE Systems . "QoE Monitor provides a single measure that captures all of the QoS criteria that an end-user cares about. This significantly lowers the costs and increases the accuracy of QoS monitoring in multi-technology networks."

"The equipment and services markets for managing converged networks is growing rapidly," said Eric Goodness, Principal Analyst with the Gartner Group. "Enterprises want the expanded functionality, flexibility and lower costs of converged networks, but they must be sure that the quality of these new services remain above minimum standards. Accomplishing this requires a cost-effective monitoring system or service that provides accurate and timely QoS performance data."

The QoE Monitor solution has multiple elements including a Control Center Server, remote agent probes known as SQRA's, and a QoE Monitor Software Module for each service to be measured. The SQRA's come equipped with multiple interfaces depending on the type of network and the specific application including IP and POTS networks. The probes are distributed at key locations throughout the network. They repeatedly initiate service calls to one another, measure the MOS value of the service quality and report the information back to the Control Center Server. The server collects and analyzes the results, and reports the findings through an interactive Web interface.

The system uses standardized MOS algorithms such as ITU-T P.862 PESQ to measure the voice and audio quality of each test call and communications session. These algorithms correlate very highly to actual human perception testing and thus provide very accurate measurements of service quality as perceived by the end-user. This approach generates a single value that accurately represents the overall quality of the session. If the value falls below an established threshold, additional parameters are available to help operators pinpoint why the results were below expectations.

Pricing and Availability: The Control Center Server, SQRAs and QoE Monitor PESQ Software Module are available today in enterprise and carrier configurations. The enterprise solution starts at $48,000 and the carrier version begins at $118,000. Both have volume discounts available for purchases of multiple SQRA's. QoE Systems also offers a hosting service where network operators may lease SQRAs and utilize a hosted Control Center Server. All offerings are available directly from QoE Systems .

QoE Systems Holding Inc. to provide uality of service testing and monitoring solutions for multimedia networks

New Firm Uses Mean Opinion Score (MOS) Measurement Techniques In The Lab And In The Network.

San Jose, CA, March 29: QoE Systems Holding Inc., "QoE Systems", today announced its vision to use ITU standards-based objective-perceptual models for Quality of Service (QoS) laboratory testing and network monitoring. Focusing on the testing and measurement needs of large enterprises and carriers, QoE Systems will provide both laboratory-based and network-based solutions. A key element of the QoE Systems vision is the use of unique MOS measurement techniques based on ITU standardized psychoacoustic models to provide more accurate measures of service quality based on the end-user's perception. This approach will empower network operators that wish to reap the cost savings and advanced service benefits of combined voice and data networks with the tools needed to maintain expected levels of voice, video and data quality.

"QoE Systems' psychoacoustic measurement approach based on standard ITU models is a superior technique for measuring multimedia QoS," said Walter van Hooff, President of QoE Systems . "Other systems simply measure isolated network parameters such as latency and jitter. These statistics can be helpful, but they do not necessarily give an accurate picture of what the end user is experiencing."

"Enterprises and carriers want to save costs and offer new advanced services through converged networks," said Stephen Elliot, Senior Analyst of Network Management at IDC. "An ongoing challenge for these network operators is how to monitor and maintain QoS to meet their service level agreements (SLA). Scalable, cost-effective, easy-to-deploy network monitoring solutions that provide accurate and actionable information will help accelerate the growth of these new networks and applications."

A strong compliment of cost-effective laboratory testing and network monitoring solutions enables carriers to provide new advanced multimedia services with competitive quality guarantees in the form of Service Level Agreements. This will improve the reliability of these services and accelerate their growth and revenue potential.

For enterprises, the bottom-line savings from switching to a single network for voice and data is very compelling, but it will not work if the Quality of Service falls below acceptable levels. A cost-effective and accurate monitoring solution that is easy to deploy and manage will provide timely information to network operators enabling them to make critical adjustments to keep users happy.

A key element of QoE Systems' approach is that it uses standardized MOS algorithms such as ITU-T P.862 PESQ for voice, to measure the QoS of individual communications sessions. These algorithms correlate very highly to actual human perception testing and thus provide very accurate measurements of service quality as perceived by the end user. This technique accurately simplifies QoS measurement to a single value resulting in cost-effective solutions that can easily be deployed in the lab and throughout a network.
