Abstract
With the emergence of 3D mobile devices available in the markets, mobile 3D video services become increasingly important for video service providers, such as Youtube and Netflix, while multi-view 3D videos are potential to bring out varied innovative applications. However, enabling multi-view 3D video services may overwhelm WiFi networks when we multicast every view of a video. In this paper, therefore, we propose to incorporate depth-image-based rendering (DIBR), which allows each mobile client to synthesize the desired view from nearby left and right views, to effectively reduce the bandwidth consumption. Moreover, due to varied channel conditions, each client may suffer from different packet loss probabilities, and retransmissions incur additional bandwidth consumption. To address this issue, we first analyze the merit of view protection via DIBR for multi-view video multicast and…
