DOI: 10.1109/access.2021.3067018
Abstract: The existing viewport-adaptive 360-degree video streaming schemes encode tiled 360-degree videos with digital-based compression. However, these schemes cause a cliff effect wherein the headset video quality drops when the channel signal-to-noise ratio (SNR) falls below… read more here.

DOI: 10.1109/tcsvt.2021.3050157
Abstract: Instead of streaming the entire omnidirectional video that induces a waste of bandwidth, the tile-based viewport adaptive streaming is preferred in practice. Tiles within users’ viewport are transmitted in high quality, while tiles elsewhere are… read more here.
