Content Steering with MPEG DASH

Content distributors routinely use multiple concurrent CDNs to distribute their live and VOD content. For performance, contractual and failover reasons, there are requirements to switch dynamically between these distribution channels at run time. A new specification being developed by the DASH Industry Forum provides a standardized means for a third-party steering service to switch a player between alternate content sources, both at start-up and dynamically while the stream is underway. This talk investigates the mechanics of this steering workflow, including manifest enhancements, player behavior, local steering for 3GPP EMBMS compatibility, steering the manifest itself, and steering ads separately from primary content. We’ll demo a working steering server and discuss compatibility and interop with HLS Content Steering.
