视频中的交互式空间导航越来越受到研究界的关注，特别是在360°视频、视频监控或感兴趣区域查看等场景中。随着更多的内容被传递到顶部，对视频的空间访问的复杂性由于需要执行比特率自适应以对网络变化做出反应而增加。在本文中，我们描述了如何空间访问可以在自适应HTTP流的上下文中执行，使用平铺的源内容，MPEG-DASH及其SRD扩展。我们描述了一个可配置的实现这些技术，在GPAC开源播放器，允许实验不同的适应政策平铺视频内容。
Interactive spatial navigation within a video is getting attention in the research community, especially in scenarios such as 360° video, video surveillance or region-of-interest viewing. With more content being delivered over the top, the complexity of spatial access to the video is increased by the need to perform bitrate adaptation to react to network variations. In this paper, we describe how spatial access can be performed in an adaptive HTTP streaming context, using tiling of the source content, MPEG-DASH and its SRD extensions. We describe a configurable implementation of these technologies, within the GPAC open-source player, allowing experimentations of different adaptation policies for tiled video content.
