Abstract

Interactive multiview video streaming (IMVS) is an application where a network client requests from server a single video view at a time but can periodically switch to other views as the video is played back uninterrupted. Existing IMVS algorithms output pre-computed frame structures that facilitate permissible view-switching while minimizing the expected transmission rate given a storage constraint. In this paper, we use real-time computation (available at a remote powerful server or media cloud) to assist the pre-computed frame structure to satisfy users' view-switch requests. In particular, we first propose a new frame type called uni-merge frame that is computed in real-time for view-switching from one single view to one target view with low transmission rate and reasonable computation cost. Then, to enable permissible view-switches to a particular target picture, we find the optimal combination of pre-computed frames and real-time computed frames - one that minimizes streaming rate subject to both storage and real-time computation constraints - using a greedy combinatorial algorithm. Experimental results show that with real-time computation, the expected streaming rate of the IMVS system can be further decreased by 50% compared to pre-encoded frame structures without real-time computation. © 2012 IEEE.
