Multi-view video transmission

The developments of camera and display technologies make recording a single scene with multiple video sequences possible．These multi-view video sequences are taken by closely spaced cameras from different angles．Each video sequence in the multi-view video represents a unique viewpoint of this scene．So users can switch the viewpoint by playing different video sequences．Applications for the multi-view video include free viewpoint TV, remote surgery system, wireless multimedia sensor networks．However, the transmission of multi-view video is much larger than conventional media．Furthermore, transmission increases with increasing number of views, which brings much more increase in bandwidth requirement.
We propose a live-encoding scheme call User dependent Multi-view video Streaming (UMS) to reduce the transmission bitrate for multi-view video．In UMS, the periodic feedback containing the position and switching speed of user is used to predict a triangle area．Frames in this triangle area are possible to be displayed in next period of time．Only these frames instead of all the frames are transmitted to reduce the transmission bitrate.
