C203: How To: Reducing Latency and Startup Times

Track C – Friday 3 November 
13:45 – 14:45

Low latency and fast startup times are KPIs for most streaming video producers, particularly for live events. Though a series of structured tests that measure startup time, latency, and network overhead, this session documents the results achieved by reducing fragment sizes, using hybrid fragment sizes, adjusting player parameters like first variant retrieved and the number of fragments retrieved before playback starts, opening a persistent connection between player and server, and other experiments. Results will be shown for computer playback as well as tvOS and Roku. Youll learn the most effective strategies for minimizing startup time and latency without swamping your network with additional HTTP requests, and what youll need to do to implement them in your encoding and delivery workflows.
