There are a range of business motivations for communications service providers (CSPs) to monitor subscriber quality of experience (QoE) for streaming video services. Whether for network engineering purposes, business intelligence insight, customer experience management initiatives, or some other reason, the ability to determine the QoE from the subscriber’s perspective, for each video stream, i...

This paper proposes a novel approach of cross layer resource allocation based on Quality of Experience (QoE) for multiple applications in downlink Long Term Evolution (LTE) systems. To maximize the level of system QoE while guaranteeing the fairness for users, we introduce a Particle Swarm Optimization (PSO) based resource block allocation algorithm which has a quicker convergence rate. It is m...

Quality of service (QoS) and quality of experience (QoE) of contemporary mobile communication networks are crucial, complex and correlated. QoS describes network performance while QoE depicts perceptual quality at the user side. A set of key performance indicators (KPIs) describes in details QoS and QoE. Our research is focused specially on mobile speech and video telephony services that are wi...

Internet video advertising is a sensitive application regarding the quality of the multimedia content, efficiency of displayed advertisement and user's attention. Therefore, video advertising have to be described with respect to Quality of Experience (QoE). Important issue represents trade-off between the Quality of Experience and ad efficiency. The analysis of payment which takes into account ...

To an end user, Quality of Experience (QoE) matters more than Quality of Service (QoS) because she is the owner of her experience, which is the result of her perception. In recent times, QoE got increasingly much attention from service providers, operators, manufacturers and researchers. Amongst others, they are interested to know how the users perceive the quality of multimedia streaming and h...

Modern stereoscopic 3DTV brings new QoE (quality of experience) to viewers, which not only enhances the 3D sensation due to the added binocular depth, but may also induce new problems such as visual discomfort. Subjective quality assessment is the conventional method to assess the QoE. However, the conventional perceived image quality concept is not enough to reveal the advantages and the drawb...

This short paper frames the importance of the Quality of Experience in the contemporary ICT environment and links it to the shift towards more user-centric approaches in innovation research. The relevance of the Living Labs approach for QoE measurement is discussed. A software tool that is based on a distributed architecture in which monitored Quality of Service (QoS) parameters, context inform...

In today's highly competitive and volatile technology market environment, Quality of Experience has become a key differentiator. However, it is unclear how to take human factors into account and how to benefit from involving participants with specific user characteristics in QoE research. Based on an online survey with online video viewers (N=533), we investigated if innovative users, who are t...

As video distribution over optical transport networks becomes more and more important, considerable focus is put on providing the appropriate quality for this transport service. A typical trade-off seen in this context is between sophisticated compression techniques used in order to save required transmission bandwidth, and the sensitivity of service quality with respect to transport network in...

Over-the-top mobile video streaming is invariably influenced by volatile network conditions which cause playback interruptions (stalling events), thereby impairing users’ quality of experience (QoE). Developing models that can accurately predict users’ QoE could enable the more efficient design of quality-control protocols for video streaming networks that reduce network operational costs while...
