Here's what you need to know about ATSC 3.0 and how you can get high-definition and 4K broadcasts from your local TV stations, at least eventually.ĪTSC stands for Advanced Television Standards Committee and is the industry organization that sets standards for digital television broadcasts. And, unless you bought your TV very recently, it likely doesn't support ATSC 3.0. The bad news is that they’re few and far between. The good news is that several stations have started to broadcast via this standard. This begs the question: How can you watch TV at its crispest and cleanest without paying anything?ĪTSC 3.0 (Opens in a new window), or NextGenTV, is a new broadcast standard that enables TV stations to transmit 1080p and even 4K video over the air. Many people have switched entirely to streaming services that offer tons of HD and 4K content, but those subscriptions can add up as well. You're more likely to get true HD channels via cable or satellite, but those services are expensive. Most channels still don’t display 1080p, and instead broadcast in inferior 720p and 1080i resolutions. When high-definition TVs first appeared, it took years for shows and movies to actually show up in HD over broadcast.
