A new version of today’s over-the-air digital TV standard will debut in 2018
You’ll soon be hearing a lot about a new television broadcast technology called “Next Gen TV” that promises better picture quality, a signal more resistant to interference, interactive features, and localized emergency alerts.
What is ATSC 3.0, and how does it differ?
The new broadcast standard updates the current standard, ATSC 1.0 standard, with a host of new features and technology. It’s based on an IP (Internet Protocol) backbone and attempts to merge broadcast TV with content from the internet.
Its promoters also promise better signal reception indoors, which is good news for apartment-dwelling cord cutters, and the interactive functions could bring a new range of services to TV viewers. That said, similar promises were made about interactive TV content in the past. Consumers have shown little appetite for it.
It uses a more modern compression system to support high-bandwidth streams, which means broadcasters will be able to send 4K UHD signals or cram more high- or standard-definition channels into the same space.
How will ATSC 3.0 impact privacy?
It will probably end up something like internet advertising, but just more annoying. After all, do you really want to see TV commercials for flights to Houston, hiking boots or computer monitors for weeks after you’ve already bought them?

The first broadcasts are due to be
on the air in Phoenix, Arizona, during the first half of 2018. Broadcasters have chosen the city as a test market to figure out the technology and how to deploy it.
The FCC isn’t giving TV stations new channel space to broadcast ATSC 3.0 and has mandated that ATSC 1.0 signals remain on the air for at least five years, so broadcasters will need to work out transmitter sharing deals. The specifics of those have yet to be decided.
From there, a lot depends on consumer adoption of the technology. That will be influenced by equipment prices and the availability of programming in 4K resolution or the type of interactive fare promised.
South Korea adopted ATSC 3.0 in mid 2017, but the number of 4K programs is still very low. This could take some time.
Will I need a new TV or antenna?
Next Gen TV will be broadcast on existing TV frequencies, so you won’t need a new antenna. But because it’s a completely new format you will need a new TV or a set-top converter box (cable subscribers will get something from their cable company).
At present, TVs or converters for Next Gen TV are not on the market. It’s too early to tell how much they will cost, but one thing is already sure: unlike the analog to digital conversion, the government won’t be subsidizing the cost of converter boxes.
One potentially troubling part of the simulcast plan is that it doesn’t require TV stations to keep signals on the air at the same quality. If Next Gen TV takes off, viewers without new TVs or converters could see existing over-the-air channels switch to lower.
