An Optimal Tile-Based Approach for Viewport-Adaptive 360-Degree Video Streaming
TL;DR: The proposed approach is able to systematically decide versions of tiles according to user head movements and network conditions by taking into account not only viewport estimation errors, but also users head movements in each segment duration.
Proceedings ArticleDOI
Buffer-based bitrate adaptation for adaptive HTTP streaming
TL;DR: A novel rate-adaptation method on client side is proposed, which allows clients to estimate buffer level in the future, and thus achieving a balance between the need for high video quality and buffer stability and performs well under varying network conditions.
Journal ArticleDOI
Adaptation method for video streaming over HTTP/2
TL;DR: An adaptation method for adaptive streaming over the new HTTP/2 protocol, leveraging its server push feature, is proposed, based on a cost function that takes into account the number of pushed segments and the client buffer level.
Proceedings ArticleDOI
A New Adaptation Approach for Viewport-adaptive 360-degree Video Streaming
TL;DR: A new adaptation approach for viewport-adaptive streaming of 360-degree videos over the Internet that is able to systematically decide quality levels of tiles according to user head movements and network conditions by taking into account not only prediction errors but also userHead movements in each adaptation interval is proposed.
Journal ArticleDOI
A client-based adaptation framework for 360-degree video streaming
TL;DR: This paper introduces for the first time the use of bitrate and quality estimation in viewport adaptive streaming of 360 videos, and shows that the proposed framework can significantly improve video quality for users.
