Abstract: This paper presents the system architecture of user-driven interactive 3D video streaming transmission,which is simple to be realized with legacy displays.First,a novel idea is proposed,in which the viewer's position is determined using face detection and tracking technology.Second,the location information is employed as feedback to the video server-side in real time.Finally,the server adaptively selects the best matched parts of video stream data with the user's viewing angle.Under the existing network bandwidth conditions,the proposed system enables the viewers to select their viewing directions at their willing and enjoy a high quality of 3D experience anywhere they like.
