摘要：

Viewport-based 360-degree video delivery is a typical method to reduce video traffic for virtual reality (VR) applications. However, viewport-based solutions cause some key issues in multi-user VR applications, including large video traffic volumes owing to redundant video transmission across multiple headset users and quality degradation owing to viewport transition. In this study, we propose a 360-degree video delivery scheme for multi-user VR applications. To overcome the abovementioned issues, the proposed approach includes JPEG-XS-based video recompression at the edge server to follow the viewport transition and hybrid unicast and multicast tile delivery to prevent redundant transmissions. Moreover, we present the results of evaluations using 360-degree video and corresponding fixation points of multiple users to show that the proposed scheme prevents redundant transmissions across multiple headset users and provides better video quality for each user than existing solutions for the same video traffic.
