Study of QoE for DASH at Sub-representational Level
… structure that can be extrapolated for refining QoE metric with multiple temporal quality operating point for a given spatial quality i.e. PSNR. In this work we use frame visual significance metric and frame loss induced distortion metric to drive a DASH sub-representational scheme that offers a …

QoS-based experience-aware adaptation in multimedia e-learning - A learner, is a learner, is a user, is a customer
… provide an appropriate “Quality of Experience” (QoE). For more than a decade, adaptive hypermedia systems have been used to adapt content and instruction to individual knowledge, goals and preferences in an effort to engage learners. However, even if the content is highly engaging it can be very …
