A user-driven interactive 3D video streaming transmission system with low network bandwidth requirements

With the rapid development of electronic and computing technology, a growing number of new applications in the area of 3D video have come into sight, including the popular interactive 3D service. In this paper, the system architecture of a user-driven interactive 3D video streaming transmission is presented, which is simple to be realized with legacy displays. In particular, a novel idea is proposed, in which the viewer´s position is determined using face detection and tracking technology, and then the location information is employed as feedback to the video server-side in real time, and at last 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.
