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.
