A subjective evaluation using crowdsourcing of Adaptive Media Playout utilizing audio-visual content features

Inter-Destination Multimedia Synchronization (IDMS) pushes social interactions to a new level. IDMS allows the users to experience multimedia together with friends, colleagues, or the family while having a real-time communication at the same time. The actual challenge of synchronizing the playout of each participant to a reference playout time is a tough task in terms of Quality of Experience (QoE). A possible solution for carrying out the synchronization is Adaptive Media Playout (AMP) where the playout speed of the multimedia is increased or decreased. In this paper we evaluate the impact of the playout variations on the QoE by adopting a crowdsourcing approach. In particular, we investigate the impact of randomly selecting content sections for adapting the playout rate compared to our approach that exploits audio-visual features of the content in order to minimize the impact on the QoE.
