Fixation Prediction for 360° Video Streaming to Head-Mounted Displays
We study the problem of predicting the Field-of-Views (FoVs) of viewerswatching 360° videos using commodityHead-MountedDisplays (HMDs). Existing solutions either use the viewer’s current orientation to approximate the viewed tiles in the future, or extrapolate the FoVs using the historical orientations and dead-reckoning algorithms. In this paper, we develop xation prediction networks that con...
متن کاملA Measurement Study of Oculus 360 Degree Video Streaming
360 degree video is a new generation of video streaming technology that promises greater immersiveness than standard video streams. This level of immersiveness is similar to that produced by virtual reality devices – users can control the eld of view using head movements rather than needing to manipulate external devices. Although 360 degree video could revolutionize streaming technology, large...
متن کاملViewport-Driven Rate-Distortion Optimized 360{\deg} Video Streaming
The growing popularity of virtual and augmented reality communications and 360◦ video streaming is moving video communication systems into much more dynamic and resource-limited operating settings. The enormous data volume of 360◦ videos requires an efficient use of network bandwidth to maintain the desired quality of experience for the end user. To this end, we propose a framework for viewport...
متن کاملA Rate Adaptation Algorithm for Tile-based 360-degree Video Streaming
In the 360-degree immersive video, a user only views a part of the entire raw video frame based on her viewing direction. However, today’s 360-degree video players always fetch the entire panoramic view regardless of users’ head movement, leading to significant bandwidth waste that can be potentially avoided. In this paper, we propose a novel adaptive streaming scheme for 360-degree videos. The...
متن کاملEstimation of Optimal Encoding Ladders for Tiled 360° VR Video in Adaptive Streaming Systems
Given the significant industrial growth of demand for virtual reality (VR), 360◦ video streaming is one of the most important VR applications that require cost-optimal solutions to achieve widespread proliferation of VR technology. Because of its inherent variability of data-intensive content types and its tiled-based encoding and streaming, 360◦ video requires new encoding ladders in adaptive ...
