About Silicondust
Silicondust develops television and broadcast technology for consumer, commercial and industry applications.
Our work spans hardware, software, cloud services and broadcast infrastructure used to receive, distribute, protect and deliver television.
Silicondust is based in Glendale, Arizona, in the Phoenix metropolitan area.
Our history
Silicondust began shipping HDHomeRun® branded products in 2007 in the US consumer market. HDHomeRun made live broadcast television available across a home network, so it could be watched on the TVs and other viewing devices connected to it.
From that start, Silicondust brought its television technology to consumer retail and commercial markets on a global scale, with solutions for homes, businesses, hotels, education facilities and other sites where live television is delivered to multiple viewing devices.
In 2025, Silicondust became an ATSC 3.0 certificate authority for NEXTGEN TV®, extending its work from television reception into the security of the broadcast itself.
Television technology from reception to delivery
Our work includes television reception and DVR for the home, commercial television distribution, ATSC 3.0 broadcast security and cloud content delivery for broadcasters.
