摘要:

随着3D移动设备在市场上的出现,移动3D视频服务对于视频服务提供商(例如Youtube和Netflix)变得越来越重要,而多视图3D视频具有带来各种创新应用的潜力。然而,当我们多播视频的每个视图时,启用多视图3D视频服务可能会压倒WiFi网络。因此,在本文中,我们建议将基于深度图像的渲染(DIBR),它允许每个移动客户端合成所需的视图从附近的左,右视图,以有效地减少带宽消耗。此外,由于不同的信道条件,每个客户端可能遭受不同的分组丢失概率,并且重传引起额外的带宽消耗。为了解决这个问题,我们首先分析了通过DIBR的多视点视频组播视图保护的优点,然后设计了一个新的协议,命名为多视点组管理协议(MVGMP),组播用户的动态组管理。仿真结果表明,我们的协议有效地减少了带宽消耗,并增加了概率为每个客户端成功地播放所需的多视图的3D视频。

英文摘要:

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 then design a new protocol, named Multi-View Group Management Protocol (MVGMP), for the dynamic group management of multicast users. Simulation results manifest that our protocol effectively reduces bandwidth consumption and increases the probability for each client to successfully playback the desired view of a multi-view 3D video.
