DASH of this, DASH of that...

It's apparent that MPEG-DASH is getting traction—or at least attention—if attendance at the 2011 StreamingMedia West show's panel on MPEG-DASH is any indicator.

It wasn't just standing-room, as alluded to in the article, but was sitting-room only. It's been quite some time since I've seen this level of interest in a topic.

A few notes that didn't make it into the article:

MPEG-DASH will never define a codec, but with DASH-264 there's a move to use an H.264 codec in an MP4 container with a common file format (CFF) and common encryption (CENC).... There's also a possibility of adding DASH-264 into the HTML5 standard, since W3C requires a codec to be considered in HTML5 but MPEG-DASH itself is codec agnostic.

Interesting note about who has been participating and who has not:

Apple has been participating in MPEG-DASH from the beginning; they have contributed actively. We've not seen Google participating in DASH, but our codec agnostic approach means that WebM could be used within DASH (we can already do with profiles around M2TS).

What about royalties? An audience member's question got this reply:

From a licensing standpoint, there is a requirement to notify ISO of their intent to license; Qualcomm and Cisco have announced they'll offer royalty-free since HTTP adaptive streaming has been done for a number of years but to get to a standard we need to see a path forward to royalty-free licensing.
