You can still get free over-the-air TV from your local broadcasters. Put up an antenna and receive your local broadcasters— like ABC, CBS, NBC, CW, PBS, Univision, and a few others—at no charge.
ATSC 3.0 does NOT use the Internet to deliver NextGenTV content like 4k UHD video. It’s an over-the-air broadcast. In addition to TV, ATSC 3.0 can deliver OTA (over the air) content to smartphones.
Free TV currently uses the original high-definition (HD) digital format designated by the ATSC 1.0. Called HD TV, this digital standard offers 1080i and 720p resolution. The ATSC 3.0 standards are designed to offer support for newer technologies, including HEVC for video channels of up to 2160p 4K resolution at 120 frames per second, wide color gamut, Dolby AC-4 and MPEG-H 3D Audio, datacasting capabilities, and more robust mobile television support.
