Multicasting of multiview 3D videos over wireless networks

Abstract

In this paper, we consider a 4G wireless network in which a number of 3D videos represented in two-view plus depth format and encoded using scalable video coders are multicasted to a group of users. We formulate the optimal 3D video multicasting problem to maximize the quality of rendered virtual views on the receivers' displays. We show that this problem is NP-Complete and present a polynomial time approximation algorithm to solve it. Our simulation-based experimental results show that our algorithm provides solutions which are within 0.3 dB of the optimal solutions while satisfying real-time requirements of multicast systems.
