“QOE MANAGEMENT IN EMERGING MULTIMEDIA SERVICES”

The realization of the paradigm of Internet anywhere, anytime and any-device and the diffusion of end-user multimedia devices with powerful and user-friendly capabilities such as smartphones, tablets pc, mobile gaming terminals and ebooks, are leading to the proliferation of a significant amount of emerging multimedia services: immersive environments, mobile online gaming, 3D virtual world, book/newspaper consumption, social networking, IPTV applications, just to cite a few. Some of these services have already reached a major market success, such as the case of newspaper/magazine mobile readers and smartphone multimedia apps. Their success could be achieved especially because a user-centered approach has been followed to design the whole process of content production, service activation, content consumption, service management and updating. Indeed, the quality of the user experience, the perceived simplicity of accessing and interacting with systems and services, and the effective and acceptable
hiding of the complexity of underlying technologies are determining factors for success or failure of these novel services, as well as graceful degradation. The management of the Quality of Experience (QoE) is then undoubtedly a crucial concept in the deployment of future successful services, and it is straightforward to be understood as well complex and stimulating to be implemented in real systems. The complexity is mainly due to the difficulty of its modeling, evaluation, and translation in what for more than a decade we have been mainly dealing with (partially in its substitution), that is the Quality of Services (QoS). Whereas QoS can be now easily measured, monitored and controlled at both the networking and application layers and
at the end-system and network sides, the quality of experience is something that is still quite intricate to be managed. The practice in evaluating the QoS can be exploited in evaluating the QoE, but it is just a starting point for a complete QoE management procedure, which should encompass at least the following activities: monitoring of the experience of the user when consuming the service, adapting the provisioning of the content on the basis of the varying context conditions (e.g. network status, user behavior, user
profile, environment), predicting potential experience level degradation, and masking quality degradation due to abrupt system changes. To have a complete control of the final user experience, all these tasks need to be performed in a coordinated way and their real effectiveness depends on the validity of the adopted user perception model.

Objectives The purpose of this special issue is to present to the magazine’s audience a concise, tutorial oriented reference of the state-of-the-art, current and future research challenges and trends on the management of QoE in emerging multimedia services. To achieve this goal the special issue seeks original research and review papers that survey and present new ideas, leading-edge research prototype development, trials and early deployment, and performance evaluations in the following areas: * Definition of QoE (Quality of Experience) for emerging services * Relationship between QoE and QoS
* Architectures for the management of the QoE in emerging multimedia services
* Offline and online prediction and evaluation of QoE * QoE-oriented multimedia traffic management * QoE-oriented multimedia source and channel coding * Testbeds for performance evaluation of QoE-oriented systems
* Middleware solutions for QoE management * Adaptive and self-configuring solutions for QoE management * Advanced, scalable service-aware QoE-oriented traffic control and management
* QoE management in heterogeneous networks

In recent years, it has been realized that the success of multimedia services or applications relies on the analysis of the entire user experience (UX). The relevance of this paradigm ranges from IPTV to video-on-demand systems offering professional TV and user-generated content that is consumed and produced ubiquitously. To obtain a pleasurable and ubiquitous user experience a large amount of aspects have to be taken into account. Major challenges in this context include the identification of relevant UX factors and the quantification of their in influence on Quality of Experience (QoE).

In the particular scenario of ubiquitous production and consumption of content, context awareness and assessment of users’ expectations play an essential role. This is further justified by the emergence of new multimedia
enhancement techniques, notably 3DTV and Free Viewpoint.
In the support of ubiquitous QoE the acquired knowledge on the context and on identified parameters affecting users’ experience could be used to improve multimedia applications and their associated content delivery mechanisms.

* Workshop objectives
The objective of this workshop consists in collecting and developing know-ledge on the following three main topics defining the session structure
of the workshop:

– Context awareness for multimedia applications (video on demand, live broadcast, 3DTV, IPTV, social aspects, sensors, GPS, semantics, energy efficiency)

– Content and context aware quality measurements (user generated& professional content, live& on demand)

– Assessing and supporting QoE in ubiquitous scenarios (constant and variable in influence factors).

* Research topics
The central research question of the workshop consists in determining key elements (including content and context information) for assessing and supporting QoE ubiquitously: These questions include, but are not limited to
the following topics:

– QoE in ubiquitous scenarios
– Context awareness
– Subj/ective and objective quality evaluation in the context of use, context-aware solutions
(situation specificity, interactivity, user-generated& professional content)
– Interplay between ubiquitous delivery and QoE support – 3D Multimedia and Free ViewPoint
– QoE support for interactive multimedia

In recent years, it has been realized that the success of multimedia services or applications not only depends on Quality of Service (QoS) parameters but also relies on the analysis of the entire user experience (UX).
The relevance of this paradigm ranges from IPTV or video-on-demand systems for distributing and sharing professional TV to user-generated content over the web. To obtain a pleasurable user experience far more aspects than QoS have to be taken into account. Major challenges in this context include the identification of relevant UX factors and the quantification of their influence on Quality of Experience (QoE). In particular, context awareness and assessment of users expectations play an essential role. This is further justified by the emergence of new multimedia enhancement techniques, notably 3DTV and Free Viewpoint.
Future Internet architectures under current research are also promising on the possibility to accommodate protocols and policies that take QoE issues into consideration. Consequently, acquired knowledge on the context and on identified parameters affecting users experience could be used to improve media delivery.

* Workshop objectives
The objective of this workshop consists in collecting and developing knowledge on the following three main topics defining the session structure
of the workshop:
– Context awareness for multimedia applications (video on demand on the web, content sharing, user-generated& professional content, IPTV, social
aspects, sensors, energy efficiency)
– Content and context aware quality measurements (user-generated& professional content, live& on demand)
– Content and context aware interplay between media service/applications and network strategies. Namely, QoE support in the future internet architectures.

* Research topics
The central research question consists in determining key elements (including
content and context information) for QoE assessment and evaluation of web.sharing.tv.content and to use this information to shape the future internet.
– Context awareness
– QoE for content sharing over the web and for IPTV
– Subj./Obj. quality evaluation in the context of use, context-aware solutions
(situation specificity, interactivity, user-generated& professional content)
– Media Transmission over the Future Internet
– 3D Multimedia and Free ViewPoint
– Interactive multimedia QoE support
