Stereoscopic contents enables a viewer to feel the sense of reality and stereopsis, and is being widely used in such various areas as broadcasting, movie, medical care, education, video conference, game, advertisement, etc[1]. Therefore there have been many researches on 3D stereoscopic technology for acquisition, compression, transmission, authoring and display. The authoring technique in 3D stereoscopic technology has dealt in virtual stereoscopic contents on the whole. Thus authoring technique for stereoscopic pictures is insufficient. When we compose a stereo scene with stereoscopic contents, stereoscopic pictures may not match the scene because each stereoscopic picture could have a different stereo camera condition. Thus, to solve this problem, stereoscopic pictures have been modified manually. It is a laborious work and will be spent much time. Also it is difficult for users who do not have an elementary knowledge of stereopsis. In this paper, we propose the method for authoring stereo scenes with a stereoscopic still picture and moving pictures. And there are no standards for stereoscopic contents in MPEG-4 systems. Thus we propose the extended MPEG-4 systems to support an interactive service with stereoscopic contents. We define new nodes for stereoscopic contents. Experimental results show that the proposed authoring method in this paper allows a user to synthesize stereoscopic contents easily and compose a scene with them conveniently.
