Proactive tile-based virtual reality (VR) video streaming employs the current tracking data of a user to predict future requested tiles, then renders and delivers the predicted tiles to be requested before playback. The quality of experience (QoE) depends on the overall performance of prediction, computing (i.e., rendering) and communication. All prior works neglect that users may have privacy requirement, i.e., not all the current tracking data are allowed to be uploaded. In this paper, we…

TLDR
This paper first adds extra camouflaged tile requests in addition to real tile requests and model the privacy requirement as the spatial degree of privacy (sDoP), then jointly optimize the durations for prediction, computing, and transmitting, aimed at maximizing the privacy-aware QoE given arbitrary predictor and configured resources.

360° Video Viewing Dataset in Head-Mounted Virtual Reality
TLDR
This paper presents datasets of both content data (such as image saliency maps and motion maps derived from 360° videos) and sensor data ( such as viewer head positions and orientations derived from HMD sensors) that can be used to optimize existing 360° video streaming applications and novel applications (like crowd-driven camera movements).
Optimizing 360 video delivery over cellular networks
TLDR
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.

Optimizing Fixation Prediction Using Recurrent Neural Networks for 360$^{\circ }$ Video Streaming in Head-Mounted Virtual Reality
TLDR
The proposed fixation prediction network based on recurrent neural network, which leverages sensor and content features, outperforms other algorithms in several aspects, such as achieving comparable video quality and reducing the rebuffering time.
Personal identifiability of user tracking data during observation of 360-degree VR video
TLDR
This work tests the identifiability of users under typical VR viewing circumstances, with no specially designed identifying task, and argues these results show nonverbal data should be understood by the public and by researchers as personally identifying data.
Probabilistic Tile Visibility-Based Server-Side Rate Adaptation for Adaptive 360-Degree Video Streaming
TLDR
A convolutional neural network (CNN)-based viewpoint prediction model is developed to capture the nonlinear relationship between the future and historical viewpoints and can achieve a near-optimal solution to the server-side rate adaptation problem for streaming tile-based adaptive 360-degree videos.
