Hardware acceleration for h.264 is now commonplace in fixed and

Kon already responded to this (repeated) misunderstanding of yours better
than I can, Craig, but perhaps too cryptically for you to internalize the
answer. Perhaps this more verbose explanation will stick?

Here is the part you are missing:
"Adobe announced last year that it was supporting HTTP Dynamic Streaming on
the Adobe Flash Platform. Adobe has added support for another format to the
offerings. Adobe is now supporting HTTP Live Streaming or HLS. HLS is a
MPEG2 transport streaming container that can be used by devices like the
iPad 2. With support for HLS within the Flash Media Server Adobe has reduced
the complexity for broadcasters looking to reach HTML5 supporting browser
like users of the Safar browser on Apple gear.
"The HLS support also allows the support of any platform where Flash is not
installed. When Flash is installed, the system will steam the video using
F4F over HTTP. The Flash Media Server with new support is being shown off at
NAB right now. "
So, to support all those non-conforming receivers out there, the *Flash
Media Server* used by the online streaming service will figure out that the
receiver is an oddball, and the *server* will use the receiver's favorite
wrapper. This is not about H.264 compression, as you keep repeating. It's
instead more about how to transmit streams over HTTP, Craig.
So, just another great opportunity for CE companies that are so inclined to
make a nuisance of themselves. For OTA broadcast media, there isn't enough
spectrum to be throwing around to play such games.
By the way, how about that MPEG-2 TS container used by your favorite
ecosystem, even when over the Internet? Not that I would mind, but I find
this strangely ironic! Did you know that the iPad depends on the same
transport as ATSC?
