'''{{PAGENAME}}''', also known as '''NextGenTV,''' is a television protocol for terrestrial (over the air) broadcasting.<ref name":0"="" name=":1">https://en.wikipedia.org/wiki/ATSC_3.0</ref> It promises to deliver 4K resolution broadcast television using modern standards like HEVC, HDR, Dolby AC-4 and MPEG-H 3D audio.<ref name=":1" />

NextGenTV has had privacy concerns over internet based viewer metrics/analytics and targeted advertising,<ref name=":1" /> voiced by FCC commissioner Geoffrey Starks in 2020.<ref>https://www.tvtechnology.com/atsc3/starks-warns-of-potential-privacy-data-issues-with-atsc-3-0</ref> More importantly, NextGenTV marked the introduction of [[Digital rights management]] and encryption to freely available television airwaves.<ref name=":1" />

The authority for encryption in ATSC 3.0 is called A3SA.<ref>https://a3sa.com/</ref> According to a article on Techhive,<ref name=":0">https://www.techhive.com/article/2009693/nextgen-tv-drm-puts-future-of-the-over-the-air-dvr-in-doubt.html</ref> restrictions that could be imposed by A3SA's DRM might include:

*Blocking remote access of tuners

*Always-on internet being required for viewing/streaming/playback

*Pairing recordings to the tuner it was recorded from

On certified devices, it was also discovered by Lon Seidman that tuner decryption certificates can expire after 10 to 30 years.<ref>https://blog.lon.tv/2024/01/30/atsc-3-tv-tuners-have-an-expiration-date-slow-progress-on-gateway-devices-and-more/</ref>

Many major US ATSC 3.0 pilot stations started encrypting their broadcasts in 2023,<ref name=":0" /><ref>https://blog.lon.tv/2023/05/15/broadcasters-roll-out-restrictive-drm-encryption-on-atsc-3-0-broadcasts/</ref> locking out users of all pre-certification ATSC 3.0 tuners without decryption support. This has led to some resource websites like [https://www.rabbitears.info/ rabbitears.info] to become concerned about their future providing information on channels due to encryption becoming more widespread. They warn the site may be unable to operate as the tools for analysis of channels become inoperable on encrypted channels.<ref>https://www.rabbitears.info/static.php?name=atsc3_encryption</ref>

In cases where encrypted channels were able to be decrypted using certified tuners, it has been reported an active internet connection is required to tune or switch between encrypted channels.<ref>https://blog.lon.tv/2023/09/03/the-adth-nextgen-tv-box-shows-us-just-how-bad-atsc-3-0-encrpytion-will-be/</ref>

LG has also encountered patent issues trying to incorporate tuners into their TVs, which resulted in a dispute with Constellation Design Inc. that ended ATSC 3.0 tuner support in new LG televisions as of September 2023.<ref name=":1" /><ref>https://blog.lon.tv/2023/09/26/new-lg-televisions-will-not-have-atsc-3-tuners-due-to-patent-dispute/</ref>
