Recent developments in visual quality monitoring by key performance indicators

Abstract

En plus de la Qualité de Service (QoS) traditionnelle, la Qualité d'Expérience (QoE) pose un réel défi pour les fournisseurs de services Internet, les services audiovisuels, les diffuseurs et les nouveaux services Over-The-Top (OTT). Par conséquent, des mesures audiovisuelles objectives sont fréquemment consacrées à la surveillance, au dépannage, à l'enquête et à la définition de repères d'applications de contenu fonctionnant en temps réel ou hors ligne. Le concept proposé ici, Monitoring of Audio Visual Quality by Key Performance Indicators (MOAVI), est capable d'isoler et de focaliser l'investigation, de mettre en place des algorithmes, d'augmenter la période de suivi et de garantir une meilleure prédiction de la qualité perceptuelle. Les indicateurs clés de performance (KPI) des artefacts MOAVI sont classés en quatre catégories, en fonction de leur origine : capture, traitement, transmission et affichage. Dans l'article, nous présentons des expériences réalisées en plusieurs étapes avec quatre dispositifs expérimentaux pour la vérification des concepts. La méthodologie prend en compte le seuil de visibilité des désagréments du compte. La méthodologie expérimentale est adaptée des Recommandations de l'Union internationale des télécommunications – Secteur de la normalisation des télécommunications (UIT-T) : P.800, P.910 et P.930. Nous présentons également les résultats des tests de vérification des KPI. Enfin, nous décrivons également la première implémentation de MOAVI KPI dans un produit commercial : la sonde NET-MOZAIC. Net Research, LLC, propose actuellement la sonde dans le cadre du système de surveillance NET-xTVMS Internet Protocol Television (IPTV) et Cable Television (CATV).

Además de la calidad de servicio (QoS) tradicional, la calidad de la experiencia (QoE) plantea un verdadero desafío para los proveedores de servicios de Internet, los servicios audiovisuales, las emisoras y los nuevos servicios Over-The-Top (Ott). Por lo tanto, con frecuencia se dedican métricas audiovisuales objetivas para monitorear, solucionar problemas, investigar y establecer puntos de referencia de aplicaciones de contenido que funcionan en tiempo real o fuera de línea. El concepto propuesto aquí, Monitoreo de la Calidad Audiovisual por Indicadores Clave de Desempeño (MOAVI), es capaz de aislar y enfocar la investigación, configurar algoritmos, aumentar el período de monitoreo y garantizar una mejor predicción de la calidad perceptual. Los indicadores clave de rendimiento (KPI) de los artefactos MOAVI se clasifican en cuatro categorías, según su origen: captura, procesamiento, transmisión y visualización. En el documento, presentamos experimentos realizados en varios pasos con cuatro configuraciones experimentales para la verificación del concepto. La metodología tiene en cuenta el umbral de visibilidad de molestias de la cuenta. La metodología experimental está adaptada de las Recomendaciones: P.800, P.910 y P.930 del Sector de Normalización de las Telecomunicaciones (UIT-T) de la Unión Internacional de Telecomunicaciones. También presentamos los resultados de las pruebas de verificación de KPI. Finalmente, también describimos la primera implementación de MOAVI KPI en un producto comercial: la sonda NET-MOZAIC. Net Research, LLC, actualmente ofrece la sonda como parte del sistema de monitoreo NET-xTVMS Internet Protocol Television (IPTV) y Cable Television (CATV).

In addition to traditional Quality of Service (QoS), Quality of Experience (QoE) poses a real challenge for Internet service providers, audio-visual services, broadcasters and new Over-The-Top (OTT) services. Therefore, objective audio-visual metrics are frequently being dedicated in order to monitor, troubleshoot, investigate and set benchmarks of content applications working in real-time or off-line. The concept proposed here, Monitoring of Audio Visual Quality by Key Performance Indicators (MOAVI), is able to isolate and focus investigation, set-up algorithms, increase the monitoring period and guarantee better prediction of perceptual quality. MOAVI artefacts Key Performance Indicators (KPI) are classified into four categories, based on their origin: capturing, processing, transmission, and display. In the paper, we present experiments carried out over several steps with four experimental set-ups for concept verification. The methodology takes into the account annoyance visibility threshold. The experimental methodology is adapted from International Telecommunication Union – Telecommunication Standardization Sector (ITU-T) Recommendations: P.800, P.910 and P.930. We also present the results of KPI verification tests. Finally, we also describe the first implementation of MOAVI KPI in a commercial product: the NET-MOZAIC probe. Net Research, LLC, currently offers the probe as a part of NET-xTVMS Internet Protocol Television (IPTV) and Cable Television (CATV) monitoring system.

بالإضافة إلى جودة الخدمة التقليدية (QoS)، تشكل جودة التجربة (QoE) تحديًا حقيقيًا لمقدمي خدمات الإنترنت والخدمات السمعية والبصرية والمذيعين والخدمات الجديدة الشاملة (OTT). لذلك، يتم تخصيص مقاييس سمعية وبصرية موضوعية بشكل متكرر من أجل مراقبة واستكشاف الأخطاء وإصلاحها والتحقيق فيها ووضع معايير لتطبيقات المحتوى التي تعمل في الوقت الفعلي أو خارج الإنترنت. المفهوم المقترح هنا، مراقبة الجودة السمعية والبصرية من خلال مؤشرات الأداء الرئيسية (MOAVI)، قادر على عزل وتركيز التحقيق، وإعداد الخوارزميات، وزيادة فترة المراقبة وضمان التنبؤ الأفضل بالجودة الإدراكية. يتم تصنيف مؤشرات الأداء الرئيسية (KPI) الخاصة بشركة موافي إلى أربع فئات، بناءً على أصلها: الالتقاط والمعالجة والإرسال والعرض. في الورقة، نقدم التجارب التي أجريت على عدة خطوات مع أربعة إعدادات تجريبية للتحقق من المفهوم. تأخذ المنهجية في الاعتبار عتبة رؤية الانزعاج. تم تكييف المنهجية التجريبية من توصيات الاتحاد الدولي للاتصالات – قطاع تقييس الاتصالات (ITU - T): P.800 و P.910 و P.930. كما نقدم نتائج اختبارات التحقق من مؤشرات الأداء الرئيسية. أخيرًا، وصفنا أيضًا التنفيذ الأول لمؤشر الأداء الرئيسي MOAVI في منتج تجاري: مسبار NET - MOZAIC. تقدم شركة نت ريسيرش ذ.م. م حاليًا المسبار كجزء من نظام مراقبة تلفزيون بروتوكول الإنترنت (IPTV) وتلفزيون الكابل (CATV) من NET - xTVMS.
