An apparatus and method for multiplexing a multi-view three-dimensional moving picture according to a user's request is disclosed. The apparatus multiplexes a multi-view three-dimensional moving pictures by receiving moving pictures and information inputted from multi-view cameras and generating multi-view encoded streams corresponding to received moving pictures and information, receiving back channel information of the user, selecting necessary multi-view encoded streams according to the back channel information and multiplexing the selected multi-view encoded streams by a frame or a field having same time information. The present invention can effectively process the multi-view three-dimensional moving picture according to the display mode and system environment requested from the user by simplifying a synchronization process.
