Exactly. And to get the content to the edge servers, there's no reason why
out-of-band schemes can't be used, such as the MVPDs already use to get
content to their MPEG-2 TS distributed VOD servers: satellite. You don't HAVE
to get stuff out to the servers over the backbone network. This also holds
true for live content. Use out of band to go as far out to the edge as
necessary.
Thank you Bert. Perhaps there is a glimmer of hope for you yet.
So for a MVPD to switch from MPEG TS to IP streams for their MVPD bundles, the
effort required is minimal; just some new hardware in the headend and perhaps
new boxes at the point of service - many customers already are buying the
broadband service and have modems.
What is Important here is that they - cable, Fios and DBS - can continue to
broadcast these linear streams to everyone in their networks rather than
handling this stuff as UDP streams. They can guarantee QOS without violating
net neutrality rules and offload a huge portion of traffic relative to access
all this stuff via the broadband side of the plant. This is why DBS bandwidth
is valuable enough for AT&T to have spent billions for DirecTV.
A streaming provider today who want to reach all devices in the
Google, Apple, Adobe, Microsoft, Samsung, etc. empires has to
encode each video in a dozen flavors,
Agreed, which is why I bitched when Apple worked so hard to make things
worse, by dropping Flash. But Craig didn't get that, it seems. And it's also
why I complain about lack of discipline in Internet streaming, which also
seems not to be understood.
Uhhhh ... Flash is still in the mix Kilroy mentioned. It did not make life any
easier, it was just another codec and set of files to maintain. The reality is
that it is getting easier, as h.264 is now widely supported both I terms of the
encoding, and in terms or hardware decoding in the devices. And HTTP protocols
have largely replaced the RTMP protocol used by Flash.
But Kilroy is correct, it still requires many options to support many devices
that get many levels of network QOS.

Craig
