Now-a-days, the media consumption model is changing from passive isolated activities towards dynamic group shared experiences. People separated in space can already interact and collaborate within the context of simultaneous media content delivery (e.g. they can launch a real time conversation during a shared video watching). However, to stimulate the acceptance and usability of those socially aware interactive media services, synchronous communications (i.e. consistent playout states) across separated locations must be guaranteed. Inter-Destination Multimedia Synchronization (IDMS) has become a key research topic to enable geographically dispersed consumers to experience a satisfying feeling of togetherness.
