Adaptive Live Video Streaming

Adaptive live streaming represents a key advancement with respect to classic progressive download streaming such as the one employed by YouTube. With adaptive streaming the video source bit-rate is automatically adapted in real-time to match the time-varying bandwidth available to the user who can experience the maximum quality.

The following videos are distributed by employing a prototype implementation of the Quality Adaptation Control algorithm which is described in the paper:

  • L. De Cicco, S. Mascolo, V. Palmisano
    Feedback Control for Adaptive Live Video Streaming
    in Proc. of ACM Multimedia Systems Conference, San Jose, CA, Feb 23-25,2011 (PDF)

The video source is adapted by following the stream-switching (or multiple bit-rate) approach: the video source is available at different bit-rates and resolutions and a controller switches from one video version to match the available bandwidth while avoiding playback interruptions and re-buffering events.

Requirements:

  • Flash player v10.0 or greater
  • In order to experience the maximum quality (720p) a dual core 2.4GHz processor or better is recommended
