Catching the Moment in Low-Latency Live Streaming (Delivery)

1:00 PM to 1:30 PM

Bandwidth prediction, which is already a difficult task, must be more accurate when lower latency is desired due to the shorter time available to react to bandwidth changes. Any inaccuracy in bandwidth prediction results in flawed rate-adaptation decisions, which will, in turn, translate into a diminished viewer experience. In this talk, we present several bandwidth prediction models (based on statistical and computational intelligence techniques) optimized for low latency, a rate-adaptation scheme (both heuristic and learning-based) and a playback speed control scheme to overhaul low-latency live streaming clients completely. The public (open) source code is available, too.

Study Group Update: Players and Playback

2:10 PM to 2:20 PM
