My responses to you and Craig are:

1. There is no reason in principle why cellco wireless TV should "not scale." 
*If* broadcasters are going to be deploying this LTE cellular net, then it can 
scale just as well as the cellco LTE can. For local games, the local cell nets 
would use this multicast/broadcast mode of LTE. Of course, there's nothing 
quite like true broadcast for scaling, however Craig has already indicated that 
the "linear model" is out. Therefore, he is assuming a two-way net like LTE, 
and not a true broadcast scheme, like ATSC or DVB-T2.

2. "Cost prohibitive" to use cellco nets is just because cellcos want it to be 
that way, and a different broadcaster OTA infrastructure will not change this. 
Cellcos CONTROL handset design. Why should cellco nets permit cell phone 
manufacturers to support the TV frequency bands? They could permit ATSC M/H 
now, but they don't. And they won't support the TV frequency bands of an LTE 
net either. Why should they?

4. The content owners, either local broadcasters or congloms, can already make 
whatever content they want available, over WiFi, white cloud or other color 
cloud, simply by allowing their stuff on the ISP nets of the area they want to 
cover.

5. I think 4G, or even the newer 3G nets, are plenty capable of carrying 
streaming video.
