A full paper entitled “QoE-aware Inter-stream Synchronization in Open N-Screens Cloud” has been accepted by the the QoE and Human-Centered Communications and Application track of IEEE Consumer Communications & Networking Conference (CCNC), Las Vegas, January 9-12, 2016. The conference is held in conjunction with the International Consumer Electronics Show (CES).
I am also a PC member of the Cloud Services and Networking track of the same conference.
The growing popularity and increasing performance of mobile devices is transforming the way in which media can be consumed, from single device playback to orchestrated multi-stream experiences across multiple devices. One of the biggest challenges in realizing such immersive media experience is the dynamic management of synchronicity between associated media streams. This is further complicated by the faceted aspects of user perception and heterogeneity of user devices and networks. This paper introduces a QoE-aware open inter-stream media synchronization framework (IMSync). IMSync employs efficient monitoring and control mechanisms, as well as a bespoke QoE impact model derived from subjective user experiments. The impact model balances the accumulative impact of re-synchronization processes and the degree of non-synchronicity to ensure the QoE. Experimental results verify the run-time performance of the framework as a foundation for immersive media experience in open N-Screens cloud.
