Abstract :
Free viewpoint video (FVV), as a new type of multimedia, is a very challenging research area. In order to achieve free viewpoint navigation in realistic scenes, many image based rendering (IBR) technologies are introduced into FVV systems. Tow most important IBR technologies are light field rendering (LFR) and depth image based rendering (DIBR). This paper will show a new LFR based FVV streaming system over broadband IP networks. Our system uses jump frame method to support scalable quality of service (QoS) to users. An I frame retransmission method in application layer collaborates with RTP/RTCP technology in video streaming ensures different level of QoS.
