DASH-based Streaming Client for View Switching in Free-viewpoint Video Systems

Image processing and communications networking technologies are evolving at a rapid pace. Users are demanding high-quality and realistic services to enjoy cultural contents such as sports and concerts. Free-viewpoint video (FVV) streaming is an active field of research that enables realistic services. FVV streaming service augments the user experience by providing different viewpoints of the same scene. The user can navigate freely and continuously to any viewpoint. In order to provide FVV streaming services, the transmission method of various on-demand user viewpoints is important. In this paper, we propose and implement a DASH-based FVV streaming client to reduce the view switching latency by receiving a number of adjacent images. We verify the performance of the proposed client and analyze the switching time and transmission data rate depending on the number of simultaneously received videos.
