The 3D video is the core technology of next generation multimedia service for providing the best quality service to the users. This paper propose the structure of the ObjectDescriptor(OD) steam which can provide the multiview video service using the current 3-Dimensional Audio/Video (3DAV) of MPEG-4. This paper defines and analyzes the structure of OD, which can provide the multiview video service by applying the expanded scope to the existing OD. In addition, it is found out that just the expansion of the existing system is not enough to supply the multiview videos which consider the interrelationship between sending part and receiving part. Accordingly, this paper suggests the structure in which the new OD is added at the sending side to enable the viewpoint switching depending on the relation between viewpoints when the multiview video is transmitted. Through the proposed method, the user interaction becomes possible according to the request of users in the multiview video service.
