This article introduces a light-weight model to evaluate the Quality of Experience (QoE) for Over‑The‑Top (OTT) audio‑visual services.
The model is based on several cutting‑edge methods presented in the literature and includes further generalisations to better approximate the Quality of Experience (QoE) perceived by users in Dynamic Adaptive Streaming over HTTP (DASH) sessions.
The model is flexible and modular and its input parameters can be customised to consider several Key Performance Indicators (KPIs) for Quality of Service (QoS). Its reduced complexity makes it a suitable candidate for lightweight assessment of QoE on heterogeneous devices such as TV sets and mobile devices, for example by implementing it in the form of a JavaScript library to integrate with off‑the‑shelf video players.
