End-to-End 360° Video Streaming over HTTP/3: Architecture and Implementation

360° video streaming represents a shift in the way media is consumed: Users can immerse themselves, interact and engage with the viewing environment. This paper proposes the design and implementation of an end-to-end 360° video streaming stack on top of emerging Internet standards such as HTTP/3 and MPQUIC. Preliminary experiments with real network traces show that, compared to single-path streaming, multi-path with stream-aware scheduler and non-blocking buffers achieves up to 25% reduction in tile download times, lower rebuffering ratio (down to 0.53), and decreasing tile misses, while providing a higher Structured Similarity Index Measure (SSIM) of around 17.2 dB.
