| Abstract | Multi-view video consists of multiple video sequences captured simultaneously from different angles by multiple closely spaced cameras. Transmission of multi-view video requires more bandwidth than conventional multimedia. To reduce the bandwidth, several protocols have been proposed for single user. This paper proposes a multi-view video streaming for multiple users. The overlapped frames that are required by multiple users are transmitted by multicast. Simulation results show that it decreases the transmission bit-rate as compared with conventinal methods. |
