DASH-IF announces Public Community Review: Candidate Technical Specification on Content Steering for DASH

On July 10th, 2022, DASH-IF published the DASH-IF Candidate Technical Specification on Content Steering for DASH is available here for community review.

Content distributors often use multiple Content Delivery Networks (CDNs) to distribute their content to the end-users. They may upload a copy of their catalogue to each CDN, or more commonly have all CDNs pull the content from a common origin. Alternate URLs are generated, one for each CDN, that point at identical content. DASH players may access alternate URLs in the event of delivery problems. Content steering describes a deterministic capability for a content distributor to switch the content source that a player uses either at start-up or midstream, by means of a remote steering service. The DASH implementation of Content Steering also supports the notion of a proxy steering server which can switch a mobile client between broadcast and unicast sources.

This is the result of the work in the Live and Ad Insertion task force in DASH-IF. The work is led by Will Law from Akamai and is supported by several DASH-IF members: Akamai, Disney Streaming, Comcast, AWS Elemental and Qualcomm.

The community review is open until September 30th, 2022. Publication is expected by December 31, 2022. Comments may be submitted through the github.

This document is a candidate Technical Specification. DASH-IF is expecting to publish this initially, but to submit the specification to a formal specification organization. The primary choice is ETSI, for which DASH-IF has a PAS agreement.
