“…However, the Mean Opinion Scores (MOS) gathered from the users through subjective tests remains the most reliable measure of video quality. To this extent, Moldovan et al [23] propose VQAMap, a mechanism that creates generic mapping rules of objective VQA metric values to the MOS scale. VQAMap takes as input subjective data from public VQA databases and automatically creates mapping rules for any VQA metric.…”

Abstract-The increasing popularity of live video streaming from mobile devices such as Facebook Live, Instagram Stories, Snapchat, etc. pressurises the network operators to increase the capacity of their networks. However, a simple increase in system capacity will not be enough without considering the provisioning of Quality of Experience (QoE) as the basis for network control, customer loyalty and retention rate and thus increase in network operators revenue. As QoE is gaining strong momentum especially with increasing users' quality expectations, the focus is now on proposing innovative solutions to enable QoE when delivering video content over heterogeneous wireless networks. In this context, this paper presents an overview of multimedia delivery solutions, identifies the problems and provides a comprehensive classification of related state-of-theart approaches following three key directions: adaptation, energy efficiency and multipath content delivery. Discussions, challenges and open issues on the seamless multimedia provisioning faced by the current and next generation of wireless networks are also provided.

“…None of these recent H.265 QoE studies has proposed a QoE prediction model specifically aimed at the scalable extension to H.265 or the 5G context. Also, they only consider packet loss [44][38][39] [45] or address a multi-user scenario where a mapping of an objective metric [46] is used to estimate QoE rather than the cost/benefit trade-off in quality offered by scalable H.265 when congestion is encountered.…”

IEEE Transactions on BroadcastingPaper Identification Number BTS-yr-xxx (DOUBLE-CLICK HERE TO EDIT) 1  Abstract-Traffic on future Fifth-Generation (5G) mobile networks is predicted to be dominated by challenging video applications such as mobile broadcasting, remote surgery and augmented reality, demanding real-time and ultra-high quality delivery. Two of the main expectations of 5G networks are that they will be able to handle Ultra High Definition (UHD) video streaming and that they will deliver services that meet the requirements of the end user's perceived quality by adopting Quality of Experience (QoE) aware network management approaches. This paper proposes a 5G-QoE framework to address the QoE modelling for UHD video flows in 5G networks. Particularly, it focuses on providing a QoE prediction model that is both sufficiently accurate and of low enough complexity to be employed as a continuous real-time indicator of the 'health' of video applications flows at the scale required in future 5G networks. The model has been developed and implemented as part of the EU 5G PPP SELFNET autonomic management framework, where it provides a primary indicator of the likely perceptual quality of UHD video application flows traversing a realistic multi-tenanted 5G mobile edge network testbed. The proposed 5G-QoE framework has been implemented in the 5G testbed, and the high accuracy of QoE prediction has been validated through comparing the predicted QoE values with not only subjective testing results but also empirical measurements in the testbed. As such, 5G-QoE would enable a holistic video flow self-optimisation system employing the cutting-edge Scalable H.265 video encoding to transmit UHD video applications in a QoE-aware manner.Index Terms-QoE, 5G networks, video streaming, UHD.

Many European countries reported a decline in the number of students who choose STEM subjects as their future career. This is due many to the fact that STEM subjects are perceived as being difficult and boring. This paper presents findings of a case study that made use of an educational game (called Loop) to teach the loop statement in a Software Development module. The game was deployed as part of the NEWTON project large scale Programming pilot run at National College of Ireland (NCI) as part of Higher Diploma in Computing-a level 8 conversion degree, during the academic year 2018/2019. 34 mature students (over 23 years old) that already hold a third level educational degree took part in the study. Pre-and post-game assessments and post-game questionnaire were employed while the Loop game was used as part of the lab sessions. Research findings indicate that majority of the students achieved improved knowledge performance in Java programming language coding of the loop statement. The positive assessment outcomes are discussed together with students' feedback in terms of game design and game usability provided in the questionnaire.
