A media synchronization method for real-time group communication in a multiple device environment

This paper proposes a media synchronization method for real-time group communication within a multiple device environment. The method controls the output time of each media unit received at multiple devices and synchronizes them, even if the arrival time of the media unit temporarily fluctuates. This fluctuation is caused by variation in bandwidth and the network delay between different access networks. This paper also evaluates the system performance, in terms of aspects such as the average time of difference between the output and input times of each media unit, in order to confirm the effectiveness of the proposal.
