Nice of you to reply to the questions I posed for Mark.
Near as I can tell Mark did not say that LTE is not useful for broadcasters. He
did note that LTE-A is not compatible with LTE and would require 3GPP approval.
He also mentioned socializing an LTE broadcast proposal and had some buy in
from the telco community until the administration rolled out their national
broadband plan, which essentially steamrolled the broadcasters.
I hope that Mark will jump in and answer my questions and clarify some of this.
Regards
Craig

Mark said quite clearly that LTE was not a good solution for big sticks, or
for robust broadcast.
Meanwhile the Telcos seem to be moving toward LTE broadcast to leverage
the modems already used in hundreds of millions of devices. And the
regulators
seem to be on board with this, seeking to reclaim spectrum from TV
broadcasters, who they seem to think are in a death spiral.
Yes, but the best solution for a system that is used primarily for 2-way
unicast is hardly to be expected to be the best solution for people who only
broadcast.
I get the impression that the ATSC once again wants to create another
proprietary standard rather that leveraging "other people's" IP. You say as
much in you post, noting that you have largely abandoned the LTE convergence
path and are working on a new proprietary ATSC standard.
By conflating two orthogonal discussions, you miss the significant points and
you create a nice conspiracy theory. The fact that the broadcasters may
select something that is a proprietary variant of DB+VB-T2 *hardly*
contradicts the point that LTE is not the optimal solution for broadcasting!
Is there a possibility of using the broadcast spectrum as a shared utility
that
is layered upon the existing LTE infrastructure, or are we going to see a
rerun
for which there is no audience?
See what Ron also said, about how carriers disable features in these phones,
Craig. But sure, the cellcos could grab all of the broadcast spectrum, and
rent out space to TV broadcasters, for on demand unicast and occasional
broadcast. That is what LTE was designed to do. Part-time broadcast.
