Abstract EN
Virtual reality (VR) provides an immersive 360-degree viewing experience and has been widely used in many areas.
However, the transmission of panoramic video usually places a large demand on bandwidth; thus, it is difficult to ensure a reliable quality of experience (QoE) under a limited bandwidth.
In this paper, we propose a field-of-view (FoV) prediction methodology based on limited FoV feedback that can fuse the heat map and FoV information to generate a user view.
The former is obtained through saliency detection, while the latter is extracted from some user perspectives randomly, and it contains the FoV information of all users.
Then, we design a QoE-driven panoramic video streaming system with a client/server (C/S) architecture, in which the server performs rate adaptation based on the bandwidth and the predicted FoV.
We then formulate it as a nonlinear integer programming (NLP) problem and propose an optimal algorithm that combines the Karush–Kuhn–Tucker (KKT) conditions with the branch-and-bound method to solve this problem.
Finally, we evaluate our system in a simulation environment, and the results show that the system performs better than the baseline.
