There is a lot of ongoing coordination between these organizations on HTTP streaming (DASH — dynamic adaptive streaming over HTTP), many of the people involved are working across these organizations, and liaisons are being sent back and forth to coordinate, etc.  For example, they have all adopted the same baseline standard that was initiated in 3GPP, and features that were developed by MPEG are being rolled back into 3GPP, etc.  It is not clear what the IETF adds in this sense (or perhaps may subtract?)  The attempt is to create one standard across the different organizations, and not disparate competing standards.

Dear Michael;

How aligned is this work with what Apple is doing ?

> (2) If there is any effort in this area by the IETF, it would be good to align with the goal of one common standard.  If there is fragmentation, it will not be good for deployment.  For example, I’ve seen emails on this list that suggest that the IETF might go in a different direction and use a different basis other than HTTP, or do something that is based on HTTP but is contrary to these other standards, and it seems that these directions will only confuse/slow down any adoption.
