What changes with ATSC 3.0
ATSC 1.0, the standard since the 2009 digital switch, sends a fixed MPEG-2 picture. ATSC 3.0 uses newer compression and internet-style delivery. That makes room for 4K and HDR, Dolby Atmos sound, stronger reception indoors and on the move, and targeted emergency alerts.
How to receive it
- NextGen TV sets. Many mid- and high-end TVs from LG, Samsung and Sony have shipped with ATSC 3.0 tuners; look for the NextGen TV logo.
- External tuners. Boxes and network tuners from several brands add ATSC 3.0 to any TV.
- Antenna. The same antenna you use today works; no special model is required.
The open questions
Broadcasters share ATSC 3.0 channels (lighthouse stations), so a station’s 3.0 signal may come from a different transmitter than its regular one. Encryption of some signals has drawn complaints from viewers and tuner makers. The FCC has an open proceeding on how and when stations may end ATSC 1.0 broadcasts. Until that is settled, the regular signal stays on the air, and nothing you own stops working.
Should you wait or buy?
If you are buying a TV anyway, a NextGen-capable set is a sensible choice. Buying one only for ATSC 3.0 is not urgent: programs on both signals are the same.
What readers want to know
Will my current TV stop working?
No. Only the ATSC 3.0 signal needs new hardware; Your current TV still gets the regular signal, which carries the same programs.
Is NextGen TV broadcast in 4K?
The standard supports it, but most stations still send 1080p or 720p. Some special events have aired in 4K.
Why does my NextGen tuner not show some channels?
Several broadcasters encrypt ATSC 3.0 signals. Certified TVs can decode them; some third-party tuners cannot.
