A control-theoretic simplification of adaptive bitrate (ABR) video streaming (opens in new tab)

arXiv:2310.00934v3 Announce Type: replace-cross Abstract: Adaptive bitrate streaming (ABR) over the HyperText Transfer Protocol (HTTP), which raises numerous delicate questions, is nowadays almost the only approach to video streaming. This paper presents elementary solutions to three key issues: 1) A straightforward feedforward control strategy for the bitrate and the buffer level via flatness-based control. 2) Closing the loop permits mitigating unavoidable mismatches and disturbances, such...
