Network and Content-Dependent Bitrate Ladder Estimation for Adaptive Bitrate Video Streaming

Pierre R. Lebreton, Kazuhisa Yamagishi

ICASSP 2021accepted

In this paper, a method is presented to estimate bitrate ladders on the basis of both content complexity and network traces. Unlike previous methods, the proposed algorithm is independent of the adaptive bitrate (ABR) control scheme used by the client. The proposed approach was evaluated in a simula…
