I still think it's a jump to think the cell companies will be all over
ATSC-M/H due to the fact their partners on the old Ch 55 now have a pay mobile TV service coming in the next generation phones (maybe some now, I don't keep up). Will they want to add a competitive service to their phones that is free and out of their control?
If they have both in a phone, Flo and MPH, they could share a broadband diode tuned receiver, but would need different decoders. If the decoding can be done totally in software with the same hardware, that improves the chances of some company like HTC that often leads the way on new phones to build one that does both.
(and aside to Trip: When the old ATT bought out the US Cell towers and customers here, US Cell was on TDMA. I think I do remember them only buying the parts of the US Cell network that TDMA. Too bad because even way back then there were the best cell in town in Gainesville back in the 1990s).
