Abstract: SphericRTC provides real-time 360-degree video communication, which allows the viewer to observe the environment in any direction from the camera location. This more allows users to more-efficiently exchange information and can be beneficial in the real-time setting. The system selects representations of 360-degree frames to allow efficient, content-adaptive delivery. The system performs joint content and bitrate adaptation in real-time by offloading expensive transformation operations to a GPU. The system demonstrates that the multiple sub-components: viewport feedback, representation selection, and joint content and bitrate adaptation, can be effectively integrated within a single framework. Compared to a baseline implementation, views in SphericRTC have consistently higher visual quality. The median Viewport-PSNR of such views is 2.25 dB higher than views in the baseline system.
