    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.

    You will lose that bet.

    See e.g articles about Sinclair offer 1m ATSC 3.0 chips for smartphones.

    Also ATSC 3.0 is not just about broadcasting. It is meant also to be for internet streaming. Lots of people do such streaming to their smartphones.

    We'll have to see actual smartphones that put it in. Myself, I'd have said no major phone, because there's little point if it's a phone that no one really buys.

    I had a phone with a built in FM radio. Whether or not a major brand (Motorola, Samsung, LG, Apple) includes an ATSC 3.0 tuner is one of those chicken and egg scenarios. Why put in a tuner if there is no or only limited content? Why offer content if there are no receiving devices? At least with this rollout there is a reason for the transmitters to be there - the home viewers. Mobile and portable TV can come along for the ride without dedicating entire broadcast channels to the service.

    ATSC 3.0 isn't streaming in the same sense as streaming over regular bandwidth. It is still a broadcast signal (one to many) and while theoretically a request for content made over existing bi-directional data networks could be fulfilled over ATSC 3.0 I would not expect to see that use. I do expect to see data feeds and possibly "VOD" programming similar to the satellite delivered VOD offered by DISH and DIRECTV. All fitting in to whatever space is left over after transmitting TV channels.

    That's a really REALLY bad example, though. Most SoC's these days have FM radio built in, but no software. You're proving yourself wrong by citing FM. :)

    I'm not proving myself wrong - you are misunderstanding the point.

    Um, ok.

    you're citing a chicken and egg scenario, and using FM to prove it. Essentially every major brand of phone has an FM tuner. There is tons of content, and lots of usage of that content, via non-phone means.

    A better example might be the *antenna* , and not the tuner. Those would make an aesthetic difference in all phones. It's also likely relevant to the post itself, given that an antenna for mobile broadcast TV in a phone form-factor doesn't really exist, at present, at least one i know of.

    Perhaps you will understand better if you read "I had a phone with a built in FM radio" as being an activated feature that the person using the device could use to listen to FM broadcasts. Not some hidden unused capability. My words were not "I had a phone with a tuner" they were "I had a phone with a radio". BTW: It was a major brand (Motorola, not iPhone).

    And the mention was intended as a side note ... mentioning a non-telephony based feature that was available before moving on to discuss a different non-telephony feature - an ATSC 3.0 tuner. Which could be used if there were ATSC 3.0 content available. (Fortunately FM broadcasts were available when I had that phone.)

    The decision to add the FM Radio feature does not rely on someone else creating a content feed that doesn't currently exist. The decision to add an ATSC 3.0 tuner relies on the hope that some day some one else will launch usable ATSC 3.0 feeds in enough places to make the activation of a tuner feature worthwhile. Qualicomm attempted to have a cellphone video service but they relied on their own transmissions. They did not launch a feature in the hope someone else would transmit content.

    And in reply to your antenna issue, my phone used the headset as an antenna (the radio played through the wired headset). I do not know if my current Motorola phone has a chipset capable of tuning FM. Current iPhones would have the issue of not having wired headsets.

    Will Microsquash's plan to provide rural broadband via unused TV spectrum put a monkey wrench in ATSC 3.0?
