“…However, the variability of quality assessments is substantial compared to short clips with the same group of individuals. These results indicate that user segmentation shall be necessary for an accurate inclusion of users' expectations, as described in [3]. Taking into account the qualitative evaluations provided by users, some of them state that "Very good quality, except a severe degradation in the middle" or "If repeated, it would be unacceptable".…”

“…Although quality in video transmissions has been thoroughly studied in recent years, it has been commonly associated to visual quality [1,2] instead of addressing the problem from a pure service standpoint. Ibarrola proposes in [3] a general model for the management of quality of service (QoS) based on ITU-T E.802, where the concept of service is linked to the service context since it modifies both users' expectations and perceptions. Less work has been devoted to the study of multimedia services in their context of use.…”

The inclusion of multimedia content in different web-based services has increased significantly. Through an extensive subjective testing campaign, we analyse the quality of experience concerning video transmissions associated to these types of services when accessed from mobile devices and mobile Internet connections. Contrary to traditional normalised quality assessment studies, we point out the service context as a key aspect in quality assessments. Specifically, we analyse the impact of the duration of the test material on quality assessments. We find out that tolerance to visual degradations is higher in the specific context of use compared to when using standardised methodologies for quality assessment, which has a significant impact in terms of commercial service acceptability. Quality in web-based media-enriched servicesThe explosion of multimedia content on the Internet has attracted a number of commercial players. New media-enriched services are constantly being deployed on the web, such as mass media, online advertising in web pages, user interaction in social networks, user-generated content sharing portals, etc. At the same time, the segment of users who access these types of services through mobile connections is growing significantly.The quality of experience (QoE) as expressed by end users for these services is of paramount importance for service and network engineers, since it eventually influences customers' willingness to use the service. Although quality in video transmissions has been thoroughly studied in recent years, it has been commonly associated to visual quality [1,2] instead of addressing the problem from a pure service standpoint. Ibarrola proposes in [3] a general model for the management of quality of service (QoS) based on ITU-T E.802, where the concept of service is linked to the service context since it modifies both users' expectations and perceptions. Less work has been devoted to the study of multimedia services in their context of use. In [4] authors overview several studies concerning the key influence of the context in service quality evaluations: the upper and lower thresholds of satisfaction seem to be attenuated in the specific context of use. In [5], users are requested to watch full length movies with different types of degradations along the video track. Results show that the perceived visual quality is considerably different when compared to the traditional short duration tests. Additionally, users show different tolerance levels when movies are played at TV or PC screens, which points out that users' expectations play a major role in service evaluations.

Advanced socio-technical systems especially handheld and mobile devices are no longer esoteric; rather they are a part of daily life for billions of people worldwide endowing a sense of every time connectedness. With larger bandwidths, powerful processing capabilities, better displays, user friendly and haptic interfaces, mobile platforms holds a promising future for social applications. However, advances in web technologies have led to the development of complex set of applications that demands a nimble and robust architecture that is adaptive to the network constraints. This has resulted in a favorable playground for mobile-aware social applications offering practitioners and researchers key architectural challenges with numerous fledgling opportunities. In this article, we elaborate upon the challenges and provide a framework for incorporating cross-layer interaction between social applications and wireless network capabilities. Specifically, we address the problem of delivering social network content to mobile devices with the required QoS. We propose a generic framework that addresses this issue. We also discuss some suitable wireless network protocols that could be utilized to provide QoS for the delivery of content generated by social applications and for reliable interactions between mobile users and social applications followed by possible future research directions.

Moreover, using service-specific parameters also increases the probability of customer satisfaction [14].…”

Inter-domain QoS-aware service provisioning is still a complex task due to the Internet heterogeneity. It is necessary to overcome several obstacles in order to achieve a scenario where providers fully interact to satisfy all customer service requirements. Some of these obstacles are service class specification and service composition. This paper presents an integrated approach for service class specification and service composition that supports the provisioning of QoS-aware services in inter-domain environments. This approach makes use of QoS performance parameters, service-specific parameters and business parameters to compose services that fulfill customer requirements and comply with providers' business expectations.
