Synchronization is a challenge in the multi-site 3D tele-immersion (3DTI) because it is complicated by the coexistence of highly correlated heterogenous streams from multiple sources, and the need for multi-stream resynchronization when user views change. To address the problems, the authors present TSync: a new multi-tier synchronization framework for 3DTI which can effectively reduce the multi-stream sync skews. The contributions are focusing on the use of timed synchronization points for multi-stream synchronization; Internet bandwidth estimation based on machine learning; the cooperative frame rate allocation for correlated multi-streams and the resynchronization protocol used when user views change.
