, 2011 This chapter discusses the various issues that surround the development stage of mobile TV services. It highlights the importance of Quality of Experience (QoE), which is a shift in paradigm away from the widely studied Quality of Service (QoS). We discuss the factors affecting QoE and the types of assessment methods used to evaluate QoE. A QoE-layered

Proceedings of the 6th International Conference on Advances in Mobile Computing and Multimedia, 2008 The streaming of multimedia contents (e.g., Mobile TV) is a bandwidth intensive service. The network operator's aim is to provide an acceptable user experience at minimal network resource usage. It is important from the network operator's perspective to be aware of: 1) the thresholds at which the user's perception of service quality becomes ...

Proceedings of the 1st Workshop on Quality of Experience (QoE) in Visual Multimedia Applications, 2020
In the past 20 years the "Quality of Experience" (QoE) has increasingly become a necessary aspect to be taken into account by the multimedia industry. In fact, the QoE has allowed to extend the concept of image quality by considering other aspects to evaluate "the delight or annoyance of a customer's experiences with a service" [1].

QoE for telemedicine: challenges and trends
SPIE Proceedings, 2013Telemedicine that involves sharing of digital data (i.e. physiological signals, 2D/3D images and videos) should meet the same standards of traditional healthcare in terms of usability, accessibility, efficiency, effectiveness and quality of clinical processes. All these requirements can be seen as elementary components that participate to the quality

Media QoE enhancement With QUIC
2016 IEEE Conference on Computer Communications Workshops (INFOCOM WKSHPS), 2016The demonstrated system is an online video streaming service using QUIC protocol as transport. Video buffer status information is gathered at the client side and it is transferred to the video content server via the object priority assignment method of QUIC.

QoE Dimensions and QoE Measurement of NGN Services
2010In varying environment such as nowadays packet-based communications, providing NGN (Next Generation Network) services with quality as in traditional voice communications to users with high expectations is a great challenge. Therefore, the following aspects of QoE (Quality of Experience) should be taken into the consideration: technical parameters ...

Potential Gains of Reactive Video QoE Enhancement by App Agnostic QoE Deduction
2016 IEEE Global Communications Conference (GLOBECOM), 2016We propose an app agnostic QoE deduction method that can be used for on-line traffic prioritization. Our implemented method extracts QoE information directly from the screen of mobile devices and this information is utilized for video traffic prioritization to improve user QoE.

Proceedings of the 2014 Conference on Internet Measurement Conference, 2014
Smartphones have become increasingly prevalent and important in our daily lives. To meet users' expectations about the Quality of Experience (QoE) of mobile applications (apps), it is essential to obtain a comprehensive understanding of app QoE and identify the critical factors that affect it. However, effectively and systematically studying the QoE of

QoE in Pervasive Telecommunication Systems
2009The concept of offering pervasive telecommunication services, i.e., services that are available anytime, anywhere and from any terminal, is very appealing. Providing pervasive services to users has been the ultimate goal of telecommunication systems for many years. We introduce pervasive systems and services from the telecommunication perspective.

The Regressive QoE Model for VoLTE
2017 31st International Conference on Advanced Information Networking and Applications Workshops (WAINA), 2017LTE is a 3GPP full IP-based standard for wireless transmission systems. Due to its characteristic of high throughput, an efficient end-to-end QoS treatment is needed in order to guarantee good quality perceived by end users. LTE provides a native QoS-aware mechanism for end-to-end service delivering based on EPS bearer and QCI.
