Interactive 3D multi-angle live streaming system

Low delay interactive 3D multi-angle live streaming system is proposed to provide users with high sensation of both depth impression and realistic feeling, by viewing 3D video and low delay interaction of camera angle change. The proposed system consists of real-time multi-view encoding part and low delay server client streaming part. The server has the live stream buffer management for extraction and delivery in synchronization of the users' requested multi-view streams, and the client has prefetching mechanism to decrease the latency of camera switching. The user can change his/her viewpoint fast, continuing to see HD quality 3D video. The video stream is formatted as a H.264 Annex H (MVC) standard and the proposed system utilizes view scalability feature of MVC.
