SiliconDust's 3.0 Tuners Alarmingly Pose a National Security Risk According to Pearl TV's Emphasis
==================================================================
In the world of digital television, the HDHomeRun device, a popular choice among viewers, has recently faced regulatory challenges. The core issue revolves around the System on Chip (SoC) produced by HiSilicon, a wholly owned subsidiary of Huawei.
Huawei is on the U.S. Commerce Department's "Entity List," a roster of companies identified as a national security threat to the integrity of the nation's communications networks. This listing has raised concerns about the use of Huawei-made components in devices like the HDHomeRun.
The Widevine Level available to the SoC in a video gateway device, such as the HDHomeRun product, is not relevant for viewers accessing "high-value content," according to SiliconDust. However, the A3SA did approve the HDHomeRun for on-device decryption by issuing Widevine security credentials in 2022, which would enable playback and recording of encrypted content protected by ATSC 3.0 encryption.
The crux of the problem lies in the A3SA's certification process. The HDHomeRun device cannot access A3SA-protected programs primarily because it has not received certification from the Atsc 3.0 Security Authority (A3SA) to decrypt these encrypted broadcasts. Pearl TV, a broadcast consortium, attributes this certification denial to SiliconDust’s choice to use Huawei-produced chips in their HDHomeRun tuners, indicating concerns likely related to security or policy restrictions involving Chinese-made hardware.
However, SiliconDust disputes this claim, calling it unfounded. The company recommends that Pearl TV consult with the ATSC 3.0 Security Authority (A3SA) to understand Widevine levels allowed by the A3SA.
For the HDHomeRun device to access all 3.0 features and high-value content, it must have a Widevine Level 1 CDM (Content Decryption Module) integrated into the underlying SoC. Most high-value content providers require Level 1 CDM to enable a device to access their 1080p and 4K content.
As we look to the future, devices like the anticipated ZapperBox device, expected later in 2025, along with more devices from other makers, are anticipated to be ATSC 3.0 gateway tuning devices. These devices may not face the same regulatory hurdles as the HDHomeRun due to the use of different SoCs.
This article was updated on July 29 to include SiliconDust's response. The July 22, 2025 response from SiliconDust to Pearl TV's filing did not deny the central assertion about the HDHomeRun device's inability to decrypt A3SA-protected programs. Instead, SiliconDust's filing rebutted points that were never claimed, such as claims about providing technology to China or receiving financial benefit from China.
In conclusion, the HDHomeRun's use of Huawei chips has led to regulatory or licensing hurdles preventing A3SA certification necessary to decrypt some protected broadcasts. This inhibits full compatibility with A3SA-protected programming, though there is some debate about the exact reasons and the scope of the approval already granted by A3SA.
- The HDHomeRun device's inability to access A3SA-protected programs is due to the device not receiving certification from the Atsc 3.0 Security Authority (A3SA) to decrypt encrypted broadcasts, a result of the device's use of Huawei-produced chips.
- The A3SA's certification process is the crux of the problem, as it prevents the HDHomeRun device from accessing A3SA-protected programs.
- The HDHomeRun device relies on a Widevine Level available in the SoC, but it is not suitable for viewers accessing "high-value content" according to SiliconDust.
- To access all 3.0 features and high-value content, the HDHomeRun device needs a Widevine Level 1 CDM integrated into the underlying SoC, most high-value content providers require.
- For future devices like the ZapperBox device, expected in 2025, and other makers' devices, the use of different SoCs may prevent them from facing the same regulatory hurdles as the HDHomeRun.
- The HDHomeRun's use of Huawei chips has raised concerns about cybersecurity and potential policy restrictions involving Chinese-made hardware.
- The future of media and digital television involves technology, policy-and-legislation, politics, and general-news debates, with concerns about data-and-cloud-computing security and the role of companies on the U.S. Commerce Department's "Entity List."
