The ability to interactively and seamlessly roam in the scenario while watching a video through IP network is an exciting visual experience. In this work, we implemented a 3D TV system with real-time data acquisition, compression, internet transmission, light field rendering, and free-viewpoint control of dynamic scenes. Our system consists of an 8?8 light field camera array, 16 producer PCs, a streaming server system and several clients. Multiple video streams are coded in a real time manner that each client can freely selects the streams for novel view rendering. Also, our system minimize the per-user transmission bit rate while maintaining multi-view simul-switching ability for each user. We believe that this is the first real-time internet streaming system that can simultaneously guarantee real time free-view point control, data storage and support arbitrary number of users. The average transmission bit rate for end user is lower than 2Mbps which is suitable for the broadband IP network.
