In order to provide stable and efficient multiview 3D video service,the P2P connection filtration mechanism and the transmission scheduling mechanism of network multiview 3D video system were proposed.P2P connection filtration mechanism evaluated the loss rate of other peers based on the channel distortion model for multiview video transmission,and VodCrawler was used to measure the key metrics which would affect P2P transmission.According to the results of the P2P connection filtration mechanism,the system provided the clients with peers that had low loss rate and better network data transmission to improve the data transmission between clients.The transmission scheduling mechanism implemented improved task allocation based on the measurement of peers to guarantee the completeness of the views and video play with QoS.Experiment results demonstrate that network multiview 3D video clients have better service quality and the video frame per second(FPS) is higher and more stable in the proposed network multiview 3D video system.
