Abstract

We present an interactive free-viewpoint video (FVV) streaming system that is based on the dynamic adaptive streaming over HTTP (DASH) standard. The system uses standard HTTP Web servers to achieve scalability with a large number of users and performs view synthesis and rate adaptation at the client-side to achieve high response time. We propose a rate adaptation logic based on sampled rate-distortion (R-D) values, which relate the distortion of synthesized view to the bit rates of the texture and depth components of the reference views, to maximize the quality of rendered virtual views. Initial results indicate that the proposed R-D-based rate adaptation strategy outperforms equal bit rate allocation among the reference streams components.
