D103: Adaptive Bitrate Algorithms: How They Work And How To Optimize Your Stack


Adaptive bitrate algorithms are paramount for delivering content that is adapted to the multitude of devices and network conditions. Striking a balance between achieving the highest quality possible without causing stalls is a complex task that involves estimating unknowns such as bandwidth and CPU stress. Another challenge is that the optimal algorithms can vary greatly depending on bitrates, stream types and whether the content is live or VoD. This presentation is designed to give broadcasters a look into how adaptive bitrate algorithms work and, using examples of open-source players such as (dash.js & hls.js), how to optimize them according to your many business and technical considerations.
