Multiview video is well known to involve interactions with audience and offer better view experience than conventional single-view video. The interactive nature of multiview video has made the service very delay-sensitive and thus imposes great challenges for providing multiview streaming service in Internet. Currently, almost none of existing works have addressed the delay issue in multiview streaming. To ensure the quality of service and offer preferable view experience for users, we propose a novel streaming framework to provide delay-guaranteed service for interactive multiview video. The basic tradeoff between consumed server bandwidth and the required delay is carefully studied. We leverage the features of MVC to keep the server bandwidth costs low while guarantee the delay constraint. In addition, we introduce a neighbor-assisted view switching scheme: peer's neighbors are involved in its switching process and their upload bandwidth resources are effectively utilized to reduce the bandwidth costs on server. Simulation results show that our proposed framework meet the delay-guaranteed requirement with restrained server bandwidth costs while maintaining scalability and resilience to users dynamics.
