“…In [18], the proposed concept, Monitoring of Audio Visual Quality by Key Performance Indicators (MOAVI), is able to isolate and focus investigation, set up algorithms, increase the monitoring period, and guarantee better prediction of perceptual quality. In [19], Ickin et al added functionality to the VideoLAN Client (VLC) media player [20] to record a set of metrics from the user interface, application-level, network-level, and the available sensors of the device. Based on these metrics, the proposed VLQoE, a QoE instrumentation for video streaming, can infer the QoE of streaming services on a smartphone.…”
