You Deserve Low-Latency Sports and We Serve It via Content-Aware Playback
summary
Claims a concrete wins: a content‑aware playback speed controller called CAPSC is implemented in dash.js, uses per‑segment event density metadata (in‑band or from third‑party sports data) to avoid speed changes during high‑importance moments, and limits speed to ±30% while targeting ~1.5–3 s live latency with a safe buffer ≈0.5–1 s. Tests on soccer traces show fewer stalls and gentler artifacts than DASH‑GS or buffer‑only controllers; demo site, source code, and award citations accompany the paper.
