Ed has a friend who is tired of paying hundreds for cable TV. Leo says to cut the cable! You can get an antenna if you're within line of sight of the transmitter and get HD TV for free. But he's concerned because he wants to use a Tableau computer and with ATSC3, he may not be able to watch TV on that, or any other TV. Leo says that according to the ATSC website, ATSC 3 will likely be incompatible because it's not backwards compatible. That baffles Leo because ATSC3 was sold with backwards compatibility as a feature. But if this is true, people will likely have to buy some sort of converter. There will be a transitional stage, and Leo suspects it'll be compatible initially. But the interactivity portions of ATSC 3 won't be. But in five years, a lot can change. It's certainly nothing to worry about at this time.
