One Quad KPI set for

all Quad-Play applications.

The Next Level of

Perceptual Quality

by OPTICOM

Requirements for Quad KPIsFixed/Mobile Convergence and the newBroadband Home generate demand fornew key performance indicators (KPIs)that tackle all dimensions of Quality ofExperience (QoE), as perceived by cus-tomers. It’s still a long way for mobile TVpodcasts and IPTV to match the perceivedquality standards of the incumbent TVbroadcast. Various metrics, often passivetests based on protocol analysis, areavailable, but do say nothing about thepayload’s shape. No-Reference payloadanalysis produces at least some estimatesof user experience, but still lacks coreinformation about the basic quality it allstarted with. For instance, your VoIP back-bone may work fine - still the far end partyis unintelligible due to transmission dis-tortions and noise caused at the sourcemobile terminal. Your passive video

stream analysis might indicate transmis-sion artefacts, when the picture is fuzzyand blurred. How do you know what a Popmusic video download should look likewithout a reference?

Experience of OPTICOM experts goes backto the launch of the first perceptual testtool almost 20 years ago. An experiencewhich clearly shows that only intrusive,reference-comparison based testing,weighted by accurate models of humanperception will produce accurate KPIs rep-resenting the user’s perceived quality:This has been the core business develop-ment of OPTICOM. In this newsletter, youwill find a stunning update on the usecases of partner products that rely onOPTICOM’s proven OEM technology – it’swell worth reading!

“With the increasing number of PEVQOEM licensees, we have reason tobelieve from our customers’ independ-ent evaluations and their feedback thatwe currently offer the best algorithm formultimedia video quality testing in themarket space. Combined with PESQ andPEAQ this is not only the most trustedA/V Quality Test Suite in the Industry,but in fact the one KPI set for all Quad-Play applications”.

2 Overview on OPTICOM’s advanced OEM technology

Video-telephony is the entrance card to3G, and there is video–conferencing, -messaging and -streaming. With 3.5G andHSDPA high quality movie and TV stream-ing becomes reality on mobile devices.And IPTV is the key to the new BroadbandHome. Again, we are talking contentbased business models. And this time cus-tomer’s QoS expectations have beenadjusted higher-than-average by stable TVreception and DVD home cinema stan-dards. OPTICOM’s family of testing algo-rithms provides PEVQ, the perceptual eval-uation of video quality. First premiered atthe 3GSM 2005 congress in Cannes, OPTI-COM just released a major technologyupdate to PEVQ™, the industry counterpart

for video testing complementing PESQ andPEAQ. PEVQ builds on earlier develop-ments of KPN Research, the developersbehind PSQM and PESQ, and has been fur-ther advanced by OPTICOM for low bit-rate 3G formats (CIF and QCIF) togetherwith leading industry and university part-ners. PEVQ is OPTICOM’s proposed candi-date for standardization of a FR (full refer-ence) video model within VQEG (the VideoQuality Experts Group), which is in theprocess of starting verification tests forfuture standardization. While MOSundoubtedly is again the key KPI figure forperceived picture quality, a number of tra-ditional (unweighted) KPIs like e.g. Blur,Blockiness, Jerkiness, Delay and PSNR are

Video Quality testing for Telephony,Multimedia and Broadband

Voice telephony still being the core basisfor wireless 3G and Quadruple-Play servic-es, the range today includes voice-confer-encing, -messaging and PTT services. Theissue of listening quality (‘How do I per-ceive the other party’s voice!?’) is comple-mented more and more by talking qualityaspects (The talker’s own voice soundingdistorted with significant echo) and con-

versational quality limits with two or moreparties interacting. New subjective andobjective metrics to tackle Talking andConversational Quality are currently underdevelopment within the ITU-T, whereas forListening Quality metrics are already wellestablished:

OPTICOM, as the sole vendor in 1996 orig-inally introduced PSQM, the first objectivelistening quality MOS measurement rec-ommended by the ITU as P.861. PESQ –today’s state-of-the-art MOS scoring algo-rithm is available since 2001 from OPTI-COM and builds on an advanced PSQM-like core. Advanced PESQ OEM versionsfor various platforms have been devised byOPTICOM since then. The latest comple-ment is P.862.2, a recent extension for theassessment of wide-band speech trans-missions. Besides the MOS value, a num-ber of supplementing KPIs are provided,like measurement of (variable) delay andseparately calculated values for speechactive and silence parts, thus giving usefulindications for cause analysis on an expertlevel. The who-is-who of the Telecom’sindustry has licensed OPTICOM’s PESQcore, so if you came across some MOS

Sure you can characterize packet arrivaltime in milliseconds and throughput bitrate in kbit/s – but what does it say?Again, you need a KPI that copes withuser’s perceived experience. And again,OPTICOM is working at the forefront ofstandardization and expects to releasePEDQ, the perceptual evaluation of data-services quality very soon. PEDQ will pro-vide a MOS that copes with the user’s per-ceived web browsing experience.

New non-voice business models finallyhave taken the center stage: Portable MP3player with integrated mobile phone, orvice versa? Even business phones cannotdo without MP3, AAC+/++ support today –there are growing business models behindmusic-on-demand services, still you haveno KPI to monitor that? Again, OPTICOMprovides the answer: PEAQ, the ITU stan-dard for perceptual evaluation of audioquality, authored by OPTICOM in 1998 anddeveloped during a four years cooperationwith leading experts is the proper tool forsound quality testing of music streams.PEAQ can handle stereo signals with CD-like sampling frequencies up to 48kHz andreport the proper MOS in the context ofITU-R listening test standards.

And not to forget – of course wehave an audio-visual KPI pair at our hands,based on combined PEAQ+PEVQ, whichmakes a great fit to detect one of the mostprominent and nasty artefacts of videotransmissions: Lip-sync problems.

value before, there is a high chance that itwas processed by our code.

OPTICOM’s advanced ECHO measurementis offered to adequately evaluate keyaspects of talking quality, and it has notonly become a most successful key featureof OPTICOM’s OPERA voice/audio qualitytester, but - besides PESQ - it is also serv-ing as the second most important trou-bleshooting KPI when OPTICOM expertsare hired by operators for consultancyprojects. Within the new PEXQ SoftwareSuite OPTICOM now also introducesPESQ-TQ, a new metrics for MOS scoringof Talking Quality.

In collaboration with two partners, in 2004OPTICOM could finalize 3SQM (P.563) as ano reference complement to P.862, thusbuilding the 4th International PerceptualMeasurement Standard in OPTICOM’sstunning business development.

And last but not least, due to OPTICOM’sstrategic collaboration with Telchemy, theIP based QoS company, we will be able tosupport VQmon analysis in our PEXQ QoStesting solution.

In 2007 the telecom industry will seenew technologies like IMS being rapid-ly deployed, while at the same timeprices for fast Internet access onmobile devices are dropping at thesame pace. These market realities putstrong pressure on standardisationbodies like the ITU to develop newmethods for the assessment of multi-media quality. As far as video quality isconcerned, standardisation is expectedto last at least until late 2008, and thisis already an optimistic view.

The good news is that nobody has towait that long, since OPTICOM isalready there and offers PEVQ today.PEVQ does significantly exceed theVQEG requirements for a multimediametric in many aspects which areimportant for real life applications.

At the same time, the ITU is reacting tothe market needs and starts workingon new recommendations for multime-dia streaming (P.NAMS), conversation-al voice quality (P.CQO) and an exten-sion for PESQ (P.OLQA). None of thesewill, however, be finalized within ashort term. Needless to say, that OPTI-COM is pushing the work by providingsolutions for all of these applicationsalready today.

While strongly being committed to theinternational standardisation, we alsosee the clear need of the industry tomeet the challenge of the new mobileand broadcast environment. We there-fore offer our full range of measure-ment algorithms just-in-time today –long before the standardization will becompleted.

7Introducing OPTICOM’s OEM PartnersTechnical Outlook

The cellular network measurement toolQVoice from the Swiss company Ascom isused by more than 170 cellular operatorsworldwide, in more than60 countries. QVoiceuses the video algorithmPEVQ from OPTICOM forits video telephony testing and the algo-rithm delivers very accurate video MOSand other results. PEVQ takes as inputthe video signal electronically captured byQVoice, and gives results online. Thiscapability enables the cellular operators toaccess/benchmark their network and serv-ice performance, and pin-point all the rel-evant issues in loading, performance andsubscriber experience.

In addition to the Video MOS, some othervideo metrics like blockiness, jerkiness,blur, PSNR and so on are also delivered byPEVQ. Video quality results are evaluatedon the Symphony equipment itself. Thisallows an online view of the results during

drive tests and a very compact format ofthe measurement data. There is also thepossibility of live recording the full video

sequences of poor qual-ity for further examina-tion with the post-pro-cessing tools.

Aptixia IxLoad is widely used by networkoperators and equipment manufacturers toassess the performance and capacity ofnew triple play serviceofferings before they aredeployed. By understand-ing subscriber Quality of Experience (QoE)before and during large scale deploy-ments, Ixia can reduce risks and acceler-ate the adoption of services such as VoIP,Video over IP, Video on Demand, and highspeed data over all common topologies.OPTICOM’s PEVQ perceptual video qualitymeasurement complements the multiplemethods IxLoad provides to measure QoEranging from the network layer throughfull-reference metrics.

Ixia’s use of the OPTICOM PEVQ videoevaluation algorithm will help complementthe IxLoad portfolio for video testing by

allowing users to obtain per-ceptual measurements on thevideo delivered by the network.

The OPTICOM PEVQ referential methodcombined with IxLoad allows automatedmeasurement of the QoE, which is ulti-mately the most important metric to havewhen designing a network.

The complexity of mobilecommunication networksis increasing drastically.Beside the classic GSM operation usedsince the early 90ties a lot of extensionshave been implemented into the networks.There are in operation new technologiessuch as GPRS, EDGE, UMTS (WCDMA),HSDPA, HSUPA, which mainly have beenused for the provision of high datathroughput.

Besides still the speech quality of thecommunication is an important factor.

Lots of mobile networks are in operation,competition is increasing in everyEuropean country. Consequently the clas-sical drive test tools are used today for aparallel, simultaneous measurement ofcoverage and QoS data. Besides alsobenchmarking tests between the variousnetworks need to be performed.

Rohde & Schwarz Drive Test Systems are

available in variousmechanical designs,always tailored for the

needs and best benefit of the user.

Due to the complexity of the networksnowadays drive tests are becoming quiteexpensive. Consequently in a single meas-urement tour everything that could bemeasured has to be measured. So, practi-cally all the measurement data are avail-able for evaluation in a post process, with-out any lack of field data.

For all the QoS measurements Rohde &Schwarz algorithms are based on ETSIstandards and ITU recommendations. Forthe Speech Quality test the Rohde &Schwarz drive test solutions are based onOPTICOM’s PESQ algorithm with a MOSpresentation.

P3 Solutions’ DSQM stands for DistributedSensor Quality Monitoring and allows fordistributed Quality of Service measurementsconsisting of an unlimited number of clients.These clients are standard smart phonesbased on the Symbian operating system.Running the DSQM client software thesmart phones are centrally administered andconfigured to for example monitor normaluser behaviour, question users about per-ceived quality or autonomously performquality measurements of voice, messagingor data services.

Via web, bluetooth or memory card aninstaller is once distributed onto the partici-pating clients to automatically install theneeded software modules depending on therequested feature set. The DSQM clientsoftware running on the terminal operatesin the background largely unnoticeable tothe user and can centrally be configured andupdated.

The software continuously contacts theDSQM server via GPRS/UMTS to uploadmeasurement data or to download newmeasurement profiles and software

updates. The actual measurements canfunctionally be divided into different operat-ing modes.

On the one hand the user behavior can beevaluated through logging the kind of servic-es used (speech, messaging and data) sup-plemented by time and position information(MONITORING MODE). This can be extend-ed through evaluating the perceived qualityof service (PQoS) in presenting a contextspecific questionnaire about the used serv-ice on the terminal display (QUESTION-NAIRE MODE). Alternatively or in addition,voice and data services can be measuredaccording to predefined Key PerformanceIndicators (KPI) during the regular serviceusage, e.g. OPTICOM’s PESQ [ITU-T P.862]voice quality or data rate. Furthermore,autonomous measurements of voice, mes-saging or data services with a highly sophis-ticated campaign scheduling with queue arepossible as well (AUTONOMOUS MODE).
