The component of internet architecture that is totally inadequate for

What makes internet TV at all possible is edge caching, where one
copy of each video segment can be sent over the backbone to edge
servers that can route the same segments to potentially millions of
e.g. Super bowl or "Breaking Bad" viewers.
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.
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.
