What silicondust uk does

Silicondust UK Ltd is a wholly-owned UK subsidiary of US-based Silicondust USA Inc., operating from Nomansland, Salisbury, and serving as the regional commercial entity for UK and European markets. The parent company, founded in 2007 and headquartered in Livermore, California with R&D in Phoenix, Arizona, designs and sells the HDHomeRun line of network-connected TV tuners under the DBA "HDHomeRun." Core consumer hardware comprises the FLEX DUO (2 tuners, $109.99), FLEX QUATRO (4 tuners, $149.99), FLEX 4K (4 tuners with ATSC 3.0/NextGen TV, $199.99), and PRIME (CableCARD for digital cable). The hardware streams live over-the-air and cable TV across home Ethernet networks to Windows, Mac, iOS, Android, Fire TV, Roku, Apple TV, Xbox, and Linux clients, with a freemium DVR service (free for live TV; annual subscription for recording) that pools tuners and storage across USB drives, NAS devices, and PCs.

Beyond consumer hardware, Silicondust operates three distinct business lines. First, the HDGrandSlam MDU and HDGrandSlam TV commercial solutions deliver live TV and on-demand recording across multi-dwelling units, hotels, government buildings, and educational facilities without internet redistribution — up to 500 streams per box (2,000 with extender), backed by a 5-year warranty. Second, in November 2025 Silicondust launched the ATSC3-CA Certificate Authority and a patent-pending OCSP solution, monetizing FullTrust and AskTrust certificates for ATSC 3.0/NextGen TV broadcasters and private RF environments such as stadiums and airports. Third, the ATSC 3.0 BEST CDN service provides 100 Gbps broadcast content delivery with encoder health monitoring and automatic failover to TV stations.

Silicondust's go-to-market blends product-led consumer sales (own e-commerce at shop.silicondust.com and shopuk.silicondust.com plus Amazon, eBay, Newegg, and Walmart) with enterprise field sales for government, education, and broadcaster accounts. Distribution spans the US, UK, Canada, Australia, New Zealand, and parts of Latin America and Asia, with products supporting ATSC 1.0/3.0 (North America), DVB-T/T2 (UK/EU), DVB-C (Europe/Asia cable), QAM (US cable), and ISDB-T (Latin America). The company is privately held with no disclosed institutional funding; founder Nick Kelsey serves as CTO. In 2026 Silicondust filed FCC construction permits for Low Power Digital TV stations across multiple US markets, signaling a strategic move from tuner vendor toward broadcast station ownership.

Scale indicators3 records

Recent moves6 records

Expansion highlights5 records

Direct peers

• Tablo (Nuvyyo): Tablo is the closest direct competitor in network-attached OTA TV tuners and DVR for cord-cutters. Both companies target the same consumer use case (over-the-air DVR over home network) with comparable pricing and feature sets, making Tablo the most relevant direct peer.
• Channel Master: Channel Master sells OTA antennas and DVR products targeting the same cord-cutter audience as HDHomeRun. Its SMARTenna + DVR bundle competes head-to-head with Silicondust's FLEX + DVR service in the US retail channel.
• AirTV (Dish Network / EchoStar): AirTV combines Sling TV streaming with a network-attached OTA tuner (AirTV Anywhere) for a similar cord-cutting bundle. Same target buyer (Sling subscribers wanting local channels), same architecture (network-attached tuner + streaming integration).

Broad incumbents

• TiVo (Xperi): TiVo pioneered consumer DVR and now offers IP-based DVR solutions and TiVo OS for smart TVs. It is a broader incumbent in the DVR/linear-TV-recording space with deeper IP and operator relationships, but overlaps directly with Silicondust's DVR and live TV use cases.
• Roku: Roku is a broad incumbent in streaming devices and the Roku Channel, increasingly absorbing live/linear TV features (Roku Live TV Guide). It does not sell OTA tuners but competes for the same end-user 'free TV' mindshare and screen time.

Emerging players

• Plex: Plex is both a partner and an emerging DVR competitor — its Plex DVR feature uses HDHomeRun-compatible tuners but bundles the media-center, live-TV, and recording experience in one app, partially absorbing the value Silicondust's own DVR app provides.
• Emby: Emby is a third-party media center (partner and partial competitor) that supports live TV and DVR via HDHomeRun tuners. Like Plex, Emby competes at the software/DVR layer while leveraging Silicondust hardware.
• Channels (Fancy Bits): Channels is a premium DVR/TV app that integrates with HDHomeRun tuners for live TV and recording. It competes at the user-experience tier with Silicondust's own HDHomeRun app, offering a paid alternative for power users.

Others

• Synology: Synology is a NAS partner but also an ecosystem adjacent — its Synology NAS devices support HDHomeRun RECORD for DVR storage, and Synology's own media server apps overlap with Silicondust's recording ecosystem, making it both a partner and an indirect competitor.
• AV Send / Heartland Video Systems: AV Send provides CDN infrastructure that Silicondust resells for ATSC 3.0 broadcasters, and Heartland Video Systems is an integration/demo partner. Both are ecosystem participants in the NextGen TV broadcast infrastructure space adjacent to Silicondust's CDN business.
