Multi-View 3D Video Multicast for Broadband IP Networks
This work addresses bandwidth efficiency for video service providers delivering multi-view 3D content over IP networks, representing an incremental improvement.
The paper tackles the high bandwidth requirement for multi-view 3D video multicast over IP networks by formulating the Multi-view and Multicast Delivery Selection Problem (MMDS) and designing the MMDEA algorithm, which reduces bandwidth consumption by 35% compared to the original scheme using Depth-Image-Based Rendering (DIBR).
With the recent emergence of 3D-supported TVs, video service providers now face an opportunity to provide high resolution multi-view 3D videos over IP networks. One simple way to support efficient communications between a video server and multiple clients is to deliver each desired view in a multicast stream. Nevertheless, it is expected that significantly increased bandwidth will be required to support the transmission of all views in multi-view 3D videos. However, the recent emergence of a new video synthesis technique called Depth-Image-Based Rendering (DIBR) suggests that multi-view 3D video does not necessarily require the transmission of all views. Therefore, we formulate a new problem, named Multi-view and Multicast Delivery Selection Problem (MMDS), and design an algorithm, called MMDEA, to find the optimal solution. Simulation results manifest that using DIBR can effectively reduce bandwidth consumption by 35% compared to the original multicast delivery scheme.
