This study focuses on the topics of Quality of Experience which is essentially focused on business users feeling. The purpose of QoE is to realize the user-centered management. QoE is how to come up from the Angle of the user service analyze network service. QoE regards the network service as one unity and considers the various aspects of affecting the network service performance. However by co...

Real-time video communication is becoming more and more important in our daily life. WebRTC-based video communication technique has attracted a lot of attentions recently. Its user Quality-of-Experience (QoE), however, faces challenges in wireless networks. This paper studies the problem of accurate prediction of QoE of WebRTC in WiFi networks. We first propose a real-time video QoE metric whic...

With the advent of information age, VR video streaming services have emerged in large numbers scenarios such as immersive entertainment, smart education, and Internet Vehicles. People are also demanding an increasing number virtual-reality (VR) services, service providers must ensure a good user experience. Therefore, quality user’s experience is receiving attention from academia industry. The ...

The increase in multimedia content on the Internet has created a renewed interest in quality assessment. There is however a main difference from the traditional quality assessment approaches, as now, the focus relies on the user perceived quality, opposed to the network centered approach classically proposed. In this paper we overview the most relevant challenges to perform Quality of Experienc...

This paper presents a preliminary study that relates the ability in performing remote control tasks with 3D video feedback and the users’ quality of experience (QoE) when users are asked to judge the video quality only. The QoE has been evaluated by means of traditional subjective quality experiments, while an objective performance indicator (alignment error) has been used in the remote control...

With the development of mobile networks, customer needs and behaviours have changed. Mobile communications means so much more than simple voice communication; there is now mobile Internet with web surfing, videophone, streaming media, and micro blogging. The objective of network optimization has gradually shifted from enhancing network performance to improve quality of experience (QoE). Therefo...

Quality of Experience (QoE) management is a prime topic of research community nowadays as video streaming, online gaming and security applications are completely reliant on the network service quality. Moreover, there are no standard models to map Quality of Service (QoS) into QoE. HTTP media streaming is primarily used for such applications due to its coherence with the Internet and simplified...

The IPTV subscription rate has increased steadily since the introduction of IPTV Video on Demand (VoD) services. We have developed a model to determine the optimum deployment strategy for IPTV delivery network from the IPTV service providers’ perspective. The analysis technique in this paper helps us determine the best deployment scenarios to support a certain number of customers within the tol...

In this paper, we assess multidimensional QoE (Quality of Experience) of HTTP-based streaming services in seeking operation to evaluate the effect of two transmission schemes: adaptive bitrate streaming and progressive download. We perform a subjective experiment with two contents and various network load conditions. In the experiment, subjects find pre-specified scenes by means of seeking the ...

Video streaming applications are a major driver for the evolution of the future Internet. In this paper we introduce a framework for QoE management for video streaming systems based on H.264/SVC codec, the scalable extension of H.264/AVC. A relevant feature is to control the user perceived quality of experience (QoE) by exploiting parameters offered by SVC. A proper design of a control mechanis...
