Road to Successfor Quality IP VideoFixed/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 in particular to matchthe perceived quality standards of theincumbent TV broadcast. Various metrics,often passive tests based on protocolanalysis, are proposed, but do say nothingabout the payload’s shape. No-Referencepayload analysis produces at least someestimates of user experience, but stilllacks core information about the basicquality it all started with. For instance,your passive video stream analysis mightindicate transmission artefacts, while the

picture is fuzzy and blurred. How do youknow what a Pop music video streamshould look like without a reference?Experience at OPTICOM reaches back tothe launch of the first perceptual test toolalmost 20 years ago. An experience whichclearly shows that only intrusive, refer-ence-comparison based testing, weightedby accurate models of human perceptionwill produce accurate KPIs representingthe user’s perceived quality: This has beenthe core business development of OPTI-COM. In this newsletter, you will find astunning update on the use cases of part-ner products that rely on OPTICOM’sproven OEM technology to pave the roadto success for Quality IP Video!

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 forMultimedia and

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

• PESQ – Perceptual Evaluation ofSpeech Quality for MOS scoring ofnarrow and wide-band telephonyvoice signals (Listening Quality)according to ITU-T P.862/P.862.1 (nar-row-band) and P.862.2 (wide-band)

• PESQ-TQ – Perceptual Evaluation ofSpeech Quality (Talking Quality) forMOS scoring of the talker’s percep-tion of his own voice (echo andsidetone)

• 3SQM – Single-sided SpeechQuality Measurement according toITU-T P.563

• ECHO – OPTICOM’s advanced EchoEvaluation

Audio Qualitytesting forstreaming MP3

• PEAQ – Perceptual Evaluation ofAudio Quality for MOS scoring ofstereo sound accompanying videostreams according to ITU-R BS.1387

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.

• PEDQ – Perceptual Evaluationof Data-Services Quality forMOS scoring of perceiveddata download and browsingQoS

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.

provided by the new PEVQ version V2.1due to popular customer requests and forbackward compatibility reasons. Futureversions will also include optional J.144support. 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.
