| Abstract | Online VR streaming faces great challenges such as the high throughput and real time interaction requirement. In this paper, we propose a novel ultra wide view based method to stream high quality VR on Internet at low bandwidth and little computation cost. First, we only transmit the region where user is looking at instead of full 360° view to save bandwidth. To achieve this goal, we split the source VR into small grid videos in advance. The grid videos are able to reconstruct any view flexibly in user end. Second, according to the fact that users generally interact at low speed, we expand the view that user requested to meet the real time interaction requirement. Besides, a low resolution full view stream is supplied to handle exceptional cases such as high speed view change. We test our solution in an experimental network. The results show remarkable bandwidth saving of over 60% in average at little computation cost while supplying the same quality of experience as local VR. |
