The next game changer for DASH, which is currently dominated by fragmented MP4 (fMP4) encoding and segmentation techniques, will be inclusion of MPEG-2 Transport Stream. Work is under way to address this issue so that Apple can join the DASH bandwagon without giving up its massive established HLS userbase.
While fMP4 and HLS are worlds apart in their approach to fragmented HTTP delivery, there's no reason to think that the two cannot co-exist within the DASH standard, in much the same way that MPEG-2, H.264, and VC-1 co-exist in the Blu-ray Disc standard.
One company in the space just might be able to pull Apple in the direction of complete industry consolidation around DASH: Netflix.
Still, with the advent of MPEG DASH and generic HTTP servers offering "plain vanilla" content serving, the industry as a whole may well see other premium content owners attempting to create their own internal CDNs -- at least for a period of time.
