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 control algorithm described in the paper:

    ELASTIC: a Client-side Controller for Dynamic Adaptive Streaming over HTTP (DASH)
    Proc. of Packet Video Workshop 2013, San Jose, CA, USA, December 2013 (PDF) (Slides: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. The figure below shows the architecture of the adaptive video streaming service that we have designed.
