A DASH-based Mulsemedia Adaptive Delivery Solution

The Dynamic Adaptive Streaming over HTTP (DASH) is a standard designed for adaptive multimedia delivery. This paper describes an adaptive multimedia and mulsemedia delivery system which employs an extension of DASH to support multiple sensorial media. Testing using a real-life test-bed shows how user satisfaction increases when employing the proposed solution which exposes users to multi-sensorial content. The motivation behind this work is the creation the first solution for remote adaptive multi-sensory media (mulsemedia) content delivery in order to enhance user satisfaction and increase their quality of experience. A DASH-based mulsemedia delivery system (DASH-MS) was built and tested. This work focuses on a fundamental issue for remote multi-sensory media systems: synchronization and shows how the proposed DASH-MS addresses it. Results of real life subjective testing indicate that the average levels of user satisfaction when exposed to content with the mulsemedia effects are better or at least equal to those when no such effects were included. Additionally, the highest value of the level of satisfaction corresponds to the case when these effects were correctly synchronized. Finally, users seem to have preferred effects in advance than late effects.
