“…In our scenario, we have three classes encoded into 30, 30, and 23 packets per GOP, respectively, when the packet size including the network coding header is set to 1500 bytes. The values of the QoE experienced in the navigation are here provided in terms of PSNR 4 . The QoE achieved with the reception of the first c classes is 29.52 dB, 37.77 dB, and 38.16 dB, for c = 1, 2, and 3, respectively, for the "Ballet" video sequence.…”

Abstract-In free viewpoint applications, the images are captured by an array of cameras that acquire a scene of interest from different perspectives. Any intermediate viewpoint not included in the camera array can be virtually synthesized by the decoder, at a quality that depends on the distance between the virtual view and the camera views available at decoder. Hence, it is beneficial for any user to receive camera views that are close to each other for synthesis. This is however not always feasible in bandwidth-limited overlay networks, where every node may ask for different camera views. In this work, we propose an optimized delivery strategy for free viewpoint streaming over overlay networks. We introduce the concept of layered quality-of-experience (QoE), which describes the level of interactivity offered to clients. Based on these levels of QoE, camera views are organized into layered subsets. These subsets are then delivered to clients through a prioritized network coding streaming scheme, which accommodates for the network and clients heterogeneity and effectively exploit the resources of the overlay network. Simulation results show that, in a scenario with limited bandwidth or channel reliability, the proposed method outperforms baseline network coding approaches, where the different levels of QoE are not taken into account in the delivery strategy optimization.
