That's a crazy dream. There is almost no one clamoring to watch broadcast TV on their phone or tablet. Look at FM support in mobile devices, Apple has never supported it (some of their older hardware even have an FM tuner has part of the chipset, but they didn't include the antenna to support it nor the software) Some Android devices do, but the number went from "the large majority of them" in the early days of Android to "a minority of them" now because few people care. If there was a clamor for watching TV on your phone, some phones would already include TV tuners. Even though ATSC 1.0 doesn't work while moving more than 10-15 mph it would work just fine in a phone or tablet while stationary, at least for the 50%+ of the population that are within 15-20 miles of their broadcast towers. But zero phones include an ATSC tuner, because no one has included it in their chipset. The DVB-T and ISDB-T standards used for TV in the rest of the world use OFDM modulation and work fine while in motion, but no phones include tuners that support those, either. I'm willing to bet there will never be a phone on the market that supports ATSC 3.0. The patents on ATSC are running out, but ATSC 3.0's will last for years to come. Qualcomm is not going to add several dollars (probably a lot more than that in reality) to the cost of their chipset for a feature almost no one wants.
