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 | 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>{{Cite web |last=Seidman |first=Lon |date=26 Sep 2023 |title=New LG Televisions Will Not Have ATSC 3 Tuners Due to Patent Dispute |url=https://blog.lon.tv/2023/09/26/new-lg-televisions-will-not-have-atsc-3-tuners-due-to-patent-dispute/ |url-status=live |access-date=28 Mar 2025 |website=Lon.tv}}</ref> | ||
SiliconDust of HDHomeRun has engaged in official correspondence 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)"<ref name=":1">{{Cite web |date=2025-07-18 |title=Pearl Ex Parte Letter re HD HomeRun (7-18-25) |url=https://www.fcc.gov/ecfs/document/107180407509394/1 |url-status=live |website=FCC.gov}}</ref> 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.<ref>{{Cite web |date=2025-07-22 |title=Silicondust Response to Pearl Ex Parte Letter (7-22-25) |url=https://www.fcc.gov/ecfs/document/10722712322683/1 |url-status=live |website=FCC.gov}}</ref> At which the two responded back and forth where Pearl TV attempted to make claim that SiliconDust is using a blacklisted chip. Pearl also made claim that SiliconDust must have a Widevine CDM license.<ref>{{Cite web |date=2025-07-25 |title=Pearl Ex Parte Letter re HD HomeRun (Reply 7-25-25) |url=https://www.fcc.gov/ecfs/document/1072583827524/1 |url-status=live |website=FCC.gov}}</ref> 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 blacklisted chip], is not relevant in any way to viewers accessing ATSC 3.0 content."<ref>{{Cite web |date=2025-07-29 |title=SiliconDust Reply to 2nd Pearl |url=https://www.fcc.gov/ecfs/document/107301849911610/1 |url-status=live |website=FCC.gov}}</ref> 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.<ref>{{Cite web |date=2025-08-01 |title=SiliconDust Ex Parte Letter re FCC meeting (7-31-25) |url=https://www.fcc.gov/ecfs/document/1080140138248/1 |url-status=live |website=FCC.gov}}</ref> ''(*'''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''').'' | |||
Pearl TV accuses SiliconDust HDHomeRun devices of using a chip manufactured by Chinese HiSilicon, which is blacklisted by the US government and uses that as their reasoning to not approve SiliconDust HDHomeRun for DRM certification suggests that any component from a blacklisted company violates the industry’s secret, non-disclosable rules concerning decryption<ref name=":1" />. However, the SiliconDust devices have FCC certification & approval for sale in the USA indicating broadcast networks are trying to regulate tuner devices despite private industry having no authority to do so. It is also worth noting, A3SA & Pearl's use of "Selectively enforcing this rule" is based on the fact that their own DRM certified device (Converter X1 by GTMedia (''A Chinese company'')) contains a similar chip that is also blacklisted by the US government. Moreover, GTMedia devices were shipped running an outdated Android OS with known security vulnerabilities and required side-loading of all apps due to the absence of the Google Play Store, further compromising user safety.<ref>{{Cite web |last=Seidman |first=Lon |date=2025-07-22 |title=Did TV Broadcasters Just Admit to Selectively Enforcing Their Own Encryption Rules? |url=https://blog.lon.tv/2025/07/22/did-tv-broadcasters-just-admit-to-selectively-enforcing-their-own-encryption-rules/ |url-status=live |website=Lon.TV Blog}}</ref> | |||
