What is an ATSC tuner?
An ATSC (Advanced Television Systems Committee) tuner, often called an ATSC receiver or HDTV tuner is a type of television tuner that allows reception of digital television (DTV) television channels transmitted by television stations in North America. While "over-the-air" broadcasts in the United States and Canada are digital, TV inputs are also capable of receiving analog "over-the-air" NTSC broadcasts. This is an option if you are exploring how to watch TV.
The ATSC tuner is typically used to access “over-the-air” broadcast television by connecting an HDTV antenna to the Live TV input using a coaxial cable.
In addition, if you subscribe to cable then you may be able to receive some digital and analog TV stations without a cable box, by connecting directly to the Live TV input on your Roku TV system.
