The growing popularity of omnidirectional or 360 video is mainly attributable to recent immersive Virtual Reality (VR) technology developments. This technology can be explored to create an immersive studying environment that allows learners to interact in the virtual world, like in the real world, thereby fostering online virtual education, which is a vital element during the Covid-19 pandemic. Since the use of HTTP/3 in video streaming has shown significant improvement in different aspects such as stream multiplexing, bandwidth allocation, and saving time, we propose a new HTTP/3-based framework for adaptive 360-degree video streaming that can provide users with a good viewing experience under time-varying network conditions and user’s head movements. In addition, an HTTP/3-based approach to deliver late layers terminated using HTTP/3‘s stream termination feature to deal with sudden throughput drops is also implemented to tackle the trade-off between network and viewport adaptivity. Finally, a tile layer updating scheme to deal with viewport estimation errors is proposed to save network resources using HTTP/3‘s stream termination feature. Experiments show that HTTP/3 can improve bit rate up to 11.40% to 26.13% and time from 26.61% to 36.20% compared to HTTP/2.
