CUBIST: High-Quality 360-Degree Video Streaming Services via Tile-based Edge Caching and FoV-Adaptive Prefetching
Dongbiao He,Jinlei Jiang,Teng Ma,Guangwen Yang,Cedric Westphal,J.J. Garcia-Luna-Aceves,Shu-Tao Xia +6 more
TL;DR: CUBIST as discussed by the authors is the first tile-based edge caching solution that incorporates proactive tile prefetching and hierarchical cache organization into reactive caching to maximize the caching benefit while reducing the cost of 360-degree video streaming.

Group-Based Adaptive Rendering System for 6DoF Immersive Video Streaming
TL;DR: In this article , a group-based adaptive rendering method for 6DoF immersive video streaming is proposed, where each group can be transmitted independently, which enables adaptive transmission depending on the user's viewport.
Proceedings ArticleDOI
Viewpoint-Switching Delay of Multi-viewpoint 360 VR in a Bandwidth-limited Environment
TL;DR: In this article, the authors proposed a method to reduce the transmission delay when attempting to change the viewpoint in a multi-view 360 video, in which a transmission method of appropriately preloading the video of the surrounding location is considered.

Automatic View Tracking in 360º Multimedia Using xAPI
TL;DR: This work proposes an automatic view tracking system based in xAPI to collect the data required to create the knowledge required to decide the viewport that is going to be delivered, and presents a use case of an interactive 360o video documentary around the migratory crisis in Greece.

Millimeter Wave and Free-space-optics for Future Dual-connectivity 6DOF Mobile Multi-user VR Streaming
TL;DR: The proposed dual-connectivity 6DOF VR streaming system analytically characterize the key components, and forms an optimization problem to maximize the immersion fidelity delivered by the system, given the WiFi and mmWave/FSO link rates, and the computing capabilities of the edge server and the users’ VR headsets.

Multiscale structural similarity for image quality assessment
TL;DR: This paper proposes a multiscale structural similarity method, which supplies more flexibility than previous single-scale methods in incorporating the variations of viewing conditions, and develops an image synthesis method to calibrate the parameters that define the relative importance of different scales.

Rate adaptation for adaptive HTTP streaming
TL;DR: A receiver-driven rate adaptation method for HTTP/TCP streaming that deploys a step-wise increase/ aggressive decrease method to switch up/down between the different representations of the content that are encoded at different bitrates is presented.
Proceedings ArticleDOI
Optimizing 360 video delivery over cellular networks
TL;DR: This paper proposes a cellular-friendly streaming scheme that delivers only 360 videos' visible portion based on head movement prediction, which can reduce bandwidth consumption by up to 80% based on a trace-driven simulation.

Towards agile and smooth video adaptation in dynamic HTTP streaming
Guibin Tian,Yong Liu +1 more
TL;DR: This paper develops a fully-functional DASH system, develops novel video rate control algorithms that balance the needs for video rate smoothness and high bandwidth utilization, and shows that a small video rate margin can lead to much improved smoothness in video rate and buffer size.
