Advanced Television Systems Committee (ATSC) is the digital successor to the analog NTSC broadcast format. It was adopted nationwide in the United States on June 12, 2009. It was adopted by 28 mandatory markets in Canada on August 31, 2011. South Korea completed its transition to ATSC on December 31, 2012. It was adopted nationwide in Mexico on December 31, 2015. and Honduras. The Dominican Republic is set to adopt ATSC on August 9, 2021. ATSC competes with: the European DVB standard, adopted by most of Europe, Africa, Asia and Oceania; the Japanese-Brazilian ISDB-Tb standard, adopted by Japan and most of South America and Central America; and the Chinese DTMB standard, adopted by China and Cuba.

The ATSC 3.0 revision would utilize H.265 compression with High Dynamic Range (HDR) capability at with video resolutions up to Ultra High Definition 3840 × 2160 at 60 fps.

It includes a "wake up" function that would allow ATSC 3.0-compatible devices to come out of sleep or standby mode when an emergency alert signal is transmitted. Hopefully this won't be triggered by 2 AM tests of the emergency broadcast system.

It would not be backward compatible with the ATSC 1.0 standard currently used for OTA broadcasts. The FCC is requiring a five year transition period where channels would simultaneously broadcast content using both ATSC 1.0 and ATSC 5.0 on different channels.

There is also mention of demographic collection that would allow targeted advertising on a street by street basis, similar to what we see with internet advertising. But I've yet to find a clear explanation of how this would work, since current broadcasts send a single out via a powerful transmitter to all within range, and then homes and businesses use an antenna to receive the signal and a tuner to translate the signal into a transport stream with video, audio and system data.

This is interesting if only because one of my arguments about 4K not being immediately worthwhile in the home was due to the lack of content -- most HD broadcasts today are heavily compressed at either 720p or 1080i. If shows were actually being made and broadcast in 4K, that changes that equation significantly.

He'll leave just as soon as he finishes dismantling net neutrality for his big ISP employers.
