May be a year or so before TV stations install the ATSC 3.0 transmitters and TV sets become available. Definitely something to look forward to.
What is ATSC3.0? Free 4K signals over-the-air = STREAM FREE TV!
ATSC 3.0 is being created with the idea that most devices will be Internet-connected. A “hybrid” system, where the main content (audio and video) will be sent over the air. Other content will get sent over broadband and integrated into the program. Cord cutters should be the most excited, as free 4K signals over-the-air is a great idea.
At a formal commemoration at CES 2018, the Advanced Television Systems Committee (ATSC), industry standards consortium for digital television, announced the release of ATSC 3.0 standards (source: anandtech)
