ATSC 3.0, also known as NextGenTV (in US) or TV 3.0 DTV+ (in Brazil)[1][2], is a television protocol for terrestrial (over the air) broadcasting. It promises to deliver over 4K resolution and 120 FPS broadcast television using modern standards like HEVC, HDR, Dolby AC-4 and MPEG-H 3D audio, alongside better "interaction among the broadcasters and the users".
Consumer impact summary
NextGenTV has had privacy concerns over internet based viewer metrics/analytics and targeted advertising, voiced by FCC commissioner Geoffrey Starks in 2020.[3] More importantly, NextGenTV marked the introduction of Digital rights management and encryption to freely available television airwaves.
The authority for encryption in ATSC 3.0 is called A3SA.[4] According to a article on Techhive,[5] restrictions that could be imposed by A3SA's DRM might include:
- Blocking or setting expiry dates on recordings
- Blocking remote access of tuners
- Always-on internet being required for viewing/streaming/playback
- Pairing recordings to the tuner it was recorded from
- "Blessing" devices that pass the A3SA's DRM certification and licensing program
The Techhive article also describes that implementation of DRM could increase the cost of tuners due to the required licensing and certification programs on vendors.
On certified devices, it was also discovered by Lon Seidman that tuner decryption certificates can expire after 10 to 30 years.[6]
Incidents
Many major US ATSC 3.0 pilot stations started encrypting their broadcasts in 2023,[5][7] locking out users of all pre-certification ATSC 3.0 tuners without decryption support. This has led to some resource websites like 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.[8]
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.[9]
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.[10]
SiliconDust of HDHomeRun has conversed in official letters with the Federal Communications Commission (FCC) in response to Pearl TV (ATSC 3.0) with regards to "Authorizing the Permissive Use of the “Next Generation” Broadcast Television Standard (GN Docket No. 16-142)"[11] pointing out Pearl TV is acting as a gatekeeper by deciding which tuners to allow and not allow even after being "certified" for NextGenTV ATSC 3.0 as well as making mention that strict exclusive use of (google) widevine prevents popular devices such as Roku, Xbox, Apple TV, iPhone, iPad, Windows, or Mac from ever accessing the encrypted channels.[12] At which the two responded back and forth where Pearl TV attempted to make claim that SiliconDust is using a banned chip by US law in their devices as their new reasoning to not approving the HDHomeRun tuners (even though the SiliconDust devices have FCC certification & approval for sale in the USA). Pearl also made claim that SiliconDust must have a Widevine CDM license.[13] To which SiliconDust responded claiming Pearl continues to push false narratives. They point out they are "not required or expected to have the Level 1 CDM license described by Pearl" as well as stating that the "SoC part used in a video gateway device [the banned chip], is not relevant in any way to viewers accessing ATSC 3.0 content."[14] In follow-up to this incident, Nicholas J Kelsey – President of Silicondust met with the FCC where he goes over in detail how the broadcast industry is attempting to use ATSC 3.0 DRM to illegally limit access to public airwaves, "The TV receiver market is being regulated by the private broadcast industry (a different industry)" by acting as gatekeeper, Stifling innovation, having "secret A3SA rules" as well as many other key points in relation to these issues.[15] (*It should be noted that discussion in regards to the A3SA specifications and rules are forbidden from being referenced in the filings due to NDAs).
