Demo Abstract: Narwhal: a DASH-based Point Cloud Video Streaming System over Wireless Networks

Hologram video is expected to be the next generation video by providing immersive viewing experiences with 6 degrees of freedom. How to efficiently transmit hologram video is one fundamental research issue to promote its applications. As one of the most popular ways to represent hologram video, point cloud video draws more and more attentions. Point cloud video streaming faces many challenges due to large source video rate and high encoding/decoding complexity. To this end, we propose a novel DASH-based point cloud video streaming system: Narwhal, which aims to maximize the user's viewing experiences by efficiently allocating the computational and communication resources. We prototype this system and verify its performance over state-of-the-art wireless networks.
