High functional interactive delivery method for a huge number of high definition videos

我们提出了一种新的多视觉视频供应系统，使众多用户能够访问任何视图区域与任何所需的分辨率交互。基本思想是预先存储基于部分区域（区块）的预编码视频流。这些多个流被动态地加入，并基于用户的观看区域位置被递送。264/AVC中基于瓦片的视频编码和一种快速瓦片流连接方案。仿真实验和实际实现验证了该方案的可行性和有效性。

We proposes a new multi-vision video provisioning system that enables numerous users to access any view area with any desired resolution interactively. The basic idea is that the partial area (tile)-based pre-coded video streams are stored in advance. These multiple streams are joined dynamically and delivered based on the user's view-area position. In this paper, the details of H.264/AVC tile-based video coding and a fast tile stream joiner scheme are presented. Simulation experiments and our practical implementation demonstrated the feasibility and effectiveness of our proposal.
