Abstract :
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 8times8 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 2 Mbps which is suitable for the broadband IP network
