Features and Specs

  • 100% transparent for end-users: no plugins or extensions to install and no page refresh required (instream switching)
  • Configurable CDN Prioritization: based on customer sensitivity to changes in video QOS
  • Instream multi-sourcing: fetching each segment from the optimal CDN for each viewer for both live and VOD streams
  • Configuration injection: per platform, per stream, tailored to each use case or subset of broadcaster’s traffic
  • Dashboard: GUI and data API for CDN traffic, bandwidth (measured by viewer devices), error rates, viewers and buffering ratio

  • Segment-by-segment decisioning to mitigate CDN failure anywhere and at any time during the session
  • Instream switching protects against the cascade effect that a CDN failure and massive wave of page refreshes can have on the video workflow
  • No single point of failure: client-side decisioning requires no persistent backend connection during the video session

  • Web: all browsers, including Chrome, Firefox, Safari, Opera, Chromium-based browsers, Edge, and IE
  • Mobile: Android, iOS
  • Connected TVs: Samsung Tizen, LG WebOS, Chromium-based set-top boxes
